Pyrolysis and Gasification of Biomass and Waste

Thermal decomposition and gasification of biomass pyrolysis gases using a hot bed of waste derived pyrolysis char.

Chars produced from the pyrolysis of different waste materials have been investigated in terms of their use as a catalyst for the catalytic cracking of biomass pyrolysis gases during the two-stage pyrolysis-gasification of biomass. The chars were produced from the pyrolysis of waste tyres, refused derived fuel and biomass in the form of date stones. The results showed that the hydrocarbon tar y...

Plasma pyrolysis and gasification of plastics waste – a review

Plasma pyrolysis integrates thermo-chemical properties of plasma using pyrolysis process for safe disposal of solid wastes. It is an environment friendly technology to generate valuable byproducts by converting municipal solid waste, biomedical waste and hazardous wastes at 800-1000°C. Plasma Pyrolysis of plastic wastes generates pyrolysis gas, which can be utilized for energy recovery via diff...

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 researc...

GASIFICATION vs COMBUSTION OF WASTE/BIOMASS IN FLUIDIZED BED REACTORS

This paper presents a comparison of commercial fluidized bed gasifiers and combustors used to recover energy from municipal solid wastes and biomass. The work reported here is excerpted from four case studies prepared for the International Energy Agency’s Bioenergy Agreement, under Task 23 (Energy from Thermal Conversion of MSW and RDF, 1998-2000) and Task 36 (Energy from Integrated Solid Waste...
