Kinetic Modelling of a Pyrolysis – Gasification Reactor

Biomass is of growing interest as a secondary energy source. Biomass could be converted to energy especially by pyrolysis or gasification. Understanding the mechanism and the kinetics of biomass pyrolysis and gasification could be the key to the design of industrial devices capable of processing vast amounts of biomass feedstock. There are multiple reactions describing the decomposition of biom...

Distribution and Contamination Hazards of Heavy Metals in Solid Residues from the Pyrolysis and Gasification of Wastewater Sewage Sludge

most of the targeted heavy metals (hms) in sewage sludge ended up in solid residues after pyrolysis and gasification, such as Cu, Zn, Cr, Ni and Pb, which their residual rates were over 70%. The bioavailability of the hms in residues decreased despite their concentrations being higher compared with in sludge. The potential eco-toxicity of each HM were ceased after pyrolysis and gasification of ...

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...

Co-Production of Activated Carbon and Bio-Oil from Agricultural Residues by Molten Salt Pyrolysis

The feasibility of co-producing activated carbon and bio-oil from rice stalk through molten salt pyrolysis is reported in this work. The results indicated that: (1) mixed ZnCl2-KCl molten salt could considerably improve the solid and liquid yield as well as the ratio of H2 and CH4 selectively (compared to the traditional ZnCl2 method), (2) an increase of pyrolysis temperature had the same impac...
