Anellotech successfully pilots Bio-TCat technology

The viability of Anellotech’s Bio-TCat technology has been exhibited by the achievement of commercially-targeted yields in its TCat-8® pilot unit in Silsbee, Texas during six months of continuous process operations.

Process yields of 22 – 24% by weight of liquid products from loblolly pine feedstock were demonstrated. Supplemental carbon monoxide (CO) output provides potential for an additional 3 – 5% yield by weight of cellulosic ethanol via third-party technologies or production of renewable electricity.

The reactor produces a liquid product containing over 98% C6+ aromatic chemicals directly from the MinFree™-pretreated feedstock. After mild hydro-treating and purification, AnelloMate products – the family of liquid products made through Bio-TCat – meet all specifications for sale as chemicals or fuel blendstocks.

Anellotech is now planning the construction of its first commercial plant and is engaging in partnership and funding discussions with existing and new strategic partners. Engineering work is expected to begin this summer and once funding is secured, the next phase of construction will begin in the second half of 2020. The first plant will be capable of processing 500 bone dry tpd of loblolly pine wood into 40 000 tpy of products including benzene, toluene, xylenes, and C9+ aromatics to use as fuels or for making bio-based plastics for packaging and consumer products. 30 000 t of carbon monoxide (CO) and other by-product gases will also be produced, for use in generating renewable electricity or as chemical feedstock.

“We are delighted with these results, as they validate the economic potential of the Bio-TCat process and give us confidence that even small, initial scales of production are viable”, said David Sudolsky, President and CEO of Anellotech. “The goal of being cost-competitive with fossil resource technologies is a reality and we look forward to on-going process improvements.

Anellotech and its partner Axens are looking forward to licensing much larger plants following this first commercialisation. These would be five-times bigger, producing 200 – 250 000 tpy of aromatics and 150 000 t of CO. This rapidly expands the availability of bio-aromatics for chemicals and fuels, providing cost-competitive solutions needed by refiners and brand owners looking to make a difference in their carbon footprints.

“We are very excited about the prospects of deploying the Bio-TCat technology commercially under license in the coming years. We expect to bring non-food, renewable solutions to the fuels and chemicals markets for products that meet sustainability goals and provide attractive returns under competitive market conditions,” affirmed Pierre Beccat, Executive Vice-President Technology Development and Innovation at Axens.
