Catalytic destruction of tars in biomass-derived gases
The Biomass and Municipal Waste Technology Division of the US Department of Energy is sponsoring studies at the Pacific Northwest Laboratory on catalytic destruction of condensible hydrocarbons (tars) in biomass-derived gases. Currently gasifiers generate a significant amount of tars in the product gases. These tars create problems with plugging in downstream equipment and with wastewater treatment. Partial oxidation of the gas stream in a secondary fluid bed of catalyst destroys the tars in biomass-derived gases while increasing the energy content of the product gas by over 20%. Catalysts that remain active for tar destruction are used in the secondary reactor which is specially designed to promote destruction of tars and minimize oxidation of combustible gases such as CO and H/sub 2/. Results of studies with different catalysts which have been tested for this application are described.
