Bionic µfuel technology unlocks potential of Lignin

As early as 2009 experiments have been conducted using pure lignin as a sample feedstock for Bionic's µfuel technology. A detailed report about the laboratory level tests has been published by a scientific partner, Erik Karlsen, in a Danish chemical journal. An English translation can be downloaded from Bionic servers: "From Lignin to Oil by Microwaves".

The central finding from the above report: the studied liquid product phase consisted of more than 85% phenols and still more than 75% methoxy phenols. This result suggests a significantly more homogeneous liquid phase from the Bionic µfuel process than reported so far in any other available paper on Lignin treatment with various (catalytic) pyrolysis methods. Commonly extremely heterogeneous combinations of complex aromatic molecules are found where good yields of highly homogeneous chemical substances are necessary for further conversion or processing into the final lignin derived building blocks which can economically serve as the raw material for future bioplastics like novel polyesters.

The conversion of Lignin into higher value products is the primary challenge for the global cellulose and wood processing industries. Lignin alone makes up a share of 25-30 wt.% of all processed dry wood for cellulose and hemicellulose pulp extraction which is later used for paper, fiber and bioethanol production.

A lot more about the composition and properties of wood can be found at the excellent Pulp & Paper Resource & Information Site.

Despite billions of R&D money spent to date convincing pathways for lignin upgrading have yet to be identified. Scientific work usually labels the pyrolysis of lignin as highly promising for the building blocks of a future biochemical industry, but no true break throughs for commercial application are reported. Thus, enormous quantities of high quality lignin, estimated at more than 50M tons/year are still seen as a waste product and used primarily as a solid fuel for conventional industrial boilers.

A Frost & Sullivan study focusing on the commercial potential of lignin predicts it will become the most important natural aromatic raw material for future biochemicals with a combined market potential of more than USD 130 Billion at current market conditions.

Being the only natural and renewable source of aromatic compounds, lignin is one of the three major components of plant cell walls which together make up 90% of the cells biomass. Possible sources are wood, wheat and rice straw and grasses.

Currently Bionic is embarking on an extensive test program with major industry players to transform the promising lab results into a successful industrial application using the Bionic µfuel range of microwave conversion reactors.

Bionic µfuel modular design proves advantageous

mf480 reactor details

Bionic µfuel reactor and plant designs have come a long way over the recent 10 years of intense R&D work in the development labs. Starting from the drawing board and moving on to CAD workstations, performing endless process simulations in the technology lab and later on the first continuous pilot, all the way to the current mf60 prototype plants many details where refined and fine tuned literally thousands of times. During all that time, however, one fundamental cornerstone of Bionic's design principles was never questioned: the extremely modular design utilizing only the most tested, most proven assembly parts and modules available preferably off the shelf. This principle effectively differentiates Bionic's µfuel technology from practically all comparable technology designs out there.

For many years the huge advantages of such a design approach for on time project delivery, operational stability, easy scaling of plant size and ultimately capital and operational expenditure could only be explained theoretically.

This has changed with the recent mf60 commercial demonstrator now in prototype testing for something over 7 months, preparing for a first continuous 250 hour run coming up around the corner. We finally have plenty of hard evidence supporting the mantra of stubbornly insisting on uncompromising modularity. During the prototype testing period dozens of small changes and adjustments have been incorporated, often completed in a few hours. And even the major mf60 redesign described in this article required a suspension of test operations for barely 3 weeks.

Following the Bionic scaling philosophy the mf60 is nothing else than a down-scaled mf480, the latter being the bionicfuel reference reactor type for standard commercial plants. However large an individual plant might get, it will be built around clustered sets of always the same mf480 reactor units and the mf480 unit can even be temporarily reduced to around half its specified capacity with a corresponding reduction in microwave units. The consequences of this concept for the early commercial roll out are enormous.

Instead of monolithic, untested conversion plants budgeted at several hundred million USD, Bionic can offer clients a project approach incorporating risk management via a well controlled scale up process. Each reactor can be factory assembled, tested and certified against specifications even before leaving the manufacturer site. After shipping the installation process on site is a matter of weeks before final client acceptance can begin.

A factory and on-site certified single reactor system can then be rapidly upgraded by simply bringing in more of the identical reactor units combining them with standard feedstock preparation and product upgrading equipment.     

More rigorous testing upcoming for the bionicfuel mf60 prototype

Since the switch has been turned for the first time in August 2013 starting up the mf60 commercial demonstrator at the premises of SMERAL in Brno the engineers performed endless test runs while improving and fixing numerous design and engineering details.

Simply put, they where doing exactly what a prototype is meant to be used for: trial, error detection and correction... Preparing a rock solid processing core for serial production that is ready for 24/7 hard core operation when it reaches a production site for installation. Most fixes required just from a couple of hours to a day or two. But eventually in early January 2014 careful review of collected test data resulted in the decision to proceed with a major redesign of the vapor off-take from the main reactor vessel, an effort which would interrupt test operations and scheduled demonstrations for several weeks.

SMERAL engineers did a great job in preparing and implementing the revised design in only 3 weeks. The almost finished result can be seen below:

redesigned mf60 reactor unit

The new design results in a significantly lower height, making the reactor more robust and energy efficient. Durability will be further improved by repositioning the microwave units for optimized cooling.

Once all measures are completed, a continuous test run for a minimum of 10 days is scheduled which will be monitored by an independent certification agency.   

The official bionicfuel video... The Past - The Present - The Future

One month after the bionicfuel mf60d went public...

It's been hectic times for everyone at Bionic ever since the bionicfuel mf60 experienced its world premier at the industry fair at Brno last month. While a demonstration reactor was on exhibition at the booth on the fairgrounds, a fully functional unit was available for demonstrations at the test location within the SMERAL factory premises.

The most impressive stream of high profile and expert visitors has in fact not ended with the fair, where the bionicfuel Technology was honored with a prestigious award "Innovative Product of the Year 2013" delivered by the Industry Minister himself. We experience an unexpected ongoing flood of interest from around the world in a visit to the demonstration plant. The waiting list is so long that any end is simply out of sight...

Another outcome of the last few weeks is quite a number of new opportunities for far reaching cooperation and project delivery agreements. We are confident, that we can publish a lot of exciting news over the coming weeks and months. The commercialization of the technology has truly begun.

Bionic µBTL mf60d demonstrator entered test phase

Earlier this week the mf60d commercial demonstrator has been switched on for the first time, a success made possible by the excellent collaboration between Bionic R&D and its prime manufacturer SMERAL s.a. Brno in the Czech Republic.

See this Post by Bionic Laboratories BLG GmbH.

A few weeks of rigorous testing and adjustments have been kicked off. This phase includes a formal certification process by independent experts. Presentations for selected clients will commence afterwards.

Full public announcements can be expected in the first half of October.

Congratulations to everyone working hard to make this a success...

Bionic history flash back: "Biomass to Liquid becomes reality"

In February 2009 Bionic published a video about the first continuous pilot of the microfuel technology. As we are about to get the first commercial prototype ready for certification it is time to look back. Soon the many lessons learned from that first pilot will become known to the interested public followers. The new MF60D release candidate contains several thousand of changes compared to the machine in the video and was actually redesigned from ground up.

The new Bionic µBTL MF60D entered the assembly phase

It has been some time since we last reported on the latest in Bionic's microfuel development. But finally the new downsized fully functional µBTL MF60D demonstrator announced in February is approaching completion. A moment we all are very excited about.

MF60D assembled without microwave units (CAD)

We are now able to share a couple of quite impressive pictures. Here are all of all the mechanical parts (still without Bionic's microwave technology and electronic control modules) while awaiting assembly.

The top down view gives an excellent perspective on what the completed assembly will look like from the inside. The rotational reactor vessel itself can be seen at the top left side with condenser parts, piping and supporting equipment positioned to the right of it.

The following picture adds the usual view providing a better understanding for the dimensions and actual size of the modules and the completed assembly. As explained before, the reactor unit and all the peripheral modules will later be installed in several standard size container frames, some stacked in two storey configurations.

After some initial test runs formal certification by the German technical verification agency TUEV will commence. Once finalized we will have a thorough look at a very long waiting list for demonstration visit requests...

The most recent published pictures documenting the MF60D assembly progress can always be found first on the Bionic Laboratories Facebook Page.

Construction of the first Bionic µBTL MF60D reactor on schedule

Manufacturing of the recently announced new Bionic mf60 reactor series is coming along as planned. Watch the short movie of the production process to see the high level of precision and quality that goes into this piece of equipment. It will be used for both, µBTL (biomass-to-liquid) and µWTL (waste-to-liquid) configurations and in addition, in a mobile configuration, for specialty applications like soil decontamination and clean up of oil spills.

A ship based version is also under consideration for a planned ambitious environmental project designed to clean up floating islands of plastic waste putting maritime life in great danger.

A high resolution version of this movie can be viewed here directly on Youtube.

The movie shows how high quality German design is manufactured at one of the oldest Czech machine builders, renown for its dedication to quality. This reactor is built to last for decades and is designed to undergo easy upgrades when more advanced microwave technology becomes available. 

New Bionic µBTL reactor type announced

Bionic microfuel mf60 core element expecting assembly

Over the last year the Bionic Fuel Group has designed a new small scale MWDP reactor mf60 which is currently under construction at Bionic's manufacturer Smeral Brno a.s. in the Czech Republic. One of the special features of the mf60 design is its capability to house a complete plant in up to 4 standard 40' containers, resulting in completely mobile MWDP processing plants. Combined with the relevant feedstock preparation modules and the necessary oil upgrading functions all MWDP feedstock types can be processed on this mobile platform. On average the unit is able to process 250kg of dry feedstock per hour.

As a reminder, MWDP, Bionic's microwave depolymerization technology economically converts organic materials like biomass, plastic waste, used tires and many more into high value liquid and solid fuels. The process utilizes a zeolite catalyst augmented by the application of modulated microwaves.

Once the core unit is completed it will undergo rigid test processing at the manufacturer's site, first internally and then under audit of a renown certification authority. The formal certification will greatly enhance funding options for several large microfuel projects currently in the pipeline. Selected clients will have the opportunity to see the unit in operation during this phase.

Subsequently the qualification plant will be adapted to fully simulate the process of plastic waste conversion. Extensive test and demonstration runs will be performed in order to fully qualify plastic waste as feedstock for large scale microfuel plants. This activity will form an important step towards a scale up process resulting in a full scale pilot plant to be installed at a waste treatment facility in Germany.

As still another step the equipment will thereafter go back to the manufacturer to get rigged up for the planned 4 container set up including all the auxiliary modules necessary for feedstock preparation and product upgrading. The included CHP does not only make the plant independent from external power supply but is also capable of converting all of the produced oil into electricity thus reducing disposal problems for shorter term demonstration runs. This fully mobile plant will go on tour to visit several of our long term potential clients for extensive on-site test and demonstration runs in preparation for long planned large plant orders.

Surprisingly we have already received a number of requests from clients who show high interest to acquire this size of plant for their own specialty purposes. Clean-up of contaminated soil and biochar production are only 2 of the potential commercial uses for this type of unit. Bionic expects to close a number of orders over the first 6 months of the year.
