New Technology to Produce Clean, Renewable Chemicals Currently Made From Petroleum.

Anellotech's core technology, Thermo Catalytic Biomass Conversion (Bio-TCat™) for production of chemicals from renewable, non-food biomass, is based on scientific research initially performed in Professor George Huber's laboratory at the University of Massachusetts-Amherst and subsequent developments by Anellotech.

Biomass (wood, sawdust, corn stover, sugar cane bagasse (byproduct), and other non-food materials) is dried and ground. The biomass is rapidly heated, and the resulting gases are immediately converted into hydrocarbons by a proprietary, reusable, sand-like zeolite catalyst. The resulting mixture of benzene, toluene and xylenes (bio-BTX), which is identical to petroleum-derived counterparts, can be further purified and separated by using well-known commercial technologies at either grass-roots or existing petrochemical infrastructures.

Competitive Advantages

Process Efficiency: Bio-TCat™ performs all process reactions in one fluid bed reactor, where biomass is thermally broken down and then catalytically converted into BTX. This single step process uses a cost-effective catalyst being jointly developed with Johnson Matthey, to produce bio-BTX in commercially-attractive yields. By going directly from biomass to BTX in one step, Anellotech does not make a highly oxygenated bio-oil intermediate products, often seen in multi-step pyrolysis processes, and so avoids the need to add significant amounts of costly hydrogen. In fact, a process byproduct stream that we plan to burn to generate electricity, could alternatively be converted to a renewable source of hydrogen via a water-gas shift reactor.

Long-term Sustainability: Since the Bio-TCat starts with biomass and generates the required process energy from the feedstock itself, the bio-aromatics products are manufactured with a very low carbon-footprint.

Low Cost, Economic Competitiveness: Anellotech's ultimate competitive advantage is its use of a one-reactor catalytic process. Also, by using renewable and readily available non-food materials, such as wood, corn stover and bagasse, the Bio-TCat process is less expensive compared to processes relying on sugar as a feedstock, and avoids competition with the food chain. As a result, these renewable-sourced chemicals are expected to be produced and sold profitably against identical, petroleum-derived BTX counterparts.


The Bio-TCat™ technology is covered under issued patents and filed patent applications owned by Anellotech as well as those licensed on an exclusive and global basis from the University of Massachusetts.
