Staged Catalytic Gasification/Steam Reforming of Pyrolysis Oil

May 21, 2009 · Gasification/steam reforming of pyrolysis oil was studied in a staged reactor concept, which consisted of an inert fluidized bed and a catalytic fixed bed. Methane and C2−C3 free syngas is produced at a single temperature around 800 °C at atmospheric pressure. By lowering the temperature of the fluidized bed (432−500 °C), its function is changed from a gasifier to an evaporator, and in

Gasification - an overview | ScienceDirect Topics

For biomass gasification with steam, carbon dioxide, or supercritical water, the overall gasification reaction is generally endothermic, and external heating is therefore required during the whole gasification process. However, for biomass gasification with air or oxygen, the overall gasification may be endothermic or exothermic. These
