Advances in Gasification and Pyrolysis Research Using Various Biomass Feedstock

This paper discusses recent advances in gasification and pyrolysis research utilizing various biomass wastes including cotton gin trash. Texas A&M University (TAMU) has recently filed a provisional patent for a modular fluidized bed gasification and pyrolysis system (Serial No. 61/302,001, February 2010). Discussions on the capabilities of both systems are explained. In addition, recent research accomplishments were identified. These research advances include the following: development of new control systems, gasification and pyrolysis of multiple feedstocks, the development of a modular system on a trailer and investigating other co-products of the systems. More interesting research studies have recently been focused on pyrolysis technologies for the production of biocrude oil from various biomass feedstock. Compounds present in the bio-oil were identified; various extraction, fractionation and catalytic procedures were outlined to generate transport fuels such as JP8, gasoline and diesel fractions. Finally, the concept on the development of mobile fast pyrolysis system for the sustainable production of bio-oil at the cotton gins was illustrated using geographic information system (GIS) mapping tools.
