Coal and Biomass Pyrolysis and Gasification – A Review

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...

New Correlations for Coal and Biomass Pyrolysis Performances with Coal-Biomass Type Number and Temperature

The pyrolysis of coal and biomass is generally reported as the mass yield of released chemicals at various temperatures, pressures, heating rates and coal or biomass type. In this work, a new coal-biomass type number, NCT, is introduced. This number is constructed from the mass fractions of carbon, hydrogen, and oxygen in the ultimate analysis. This number is unique for each coal or biomass typ...

Sub Topic: Coal and Biomass Combustion and Gasification

Results are reported from recent tests where hydrothermal flames spontaneously ignited in a Supercritical Water Oxidation (SCWO) Test Cell. Hydrothermal flames are generally categorized as flames that occur when appropriate concentrations of fuel and oxidizer are present in supercritical water (SCW); i.e., water at conditions above its critical point (218 atm and 374 °C). A co-flow injector was...

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...
