Evaluation of Processes for Removal of Particulates, Tars and Oils from Biomass Gasifier Product Gases

摘要

For biomass gasification to make a significant contribution to the energy picture in the next decade, emphasis must be placed on the generation of clean, pollutant-free gas products. This paper attempts to quantify levels of particulates, tars, oils, and various other pollutants generated by biomass gasifiers of all types. Data from a bench-scale fluidized bed is presented which gives pollutant concentrations and compositions. End uses for biomass gases and appropriate gas cleaning technologies are examined. Complete systems analysis is used to predict the performance of various gasifier/gas-cleanup/end-use combinations. Further research needs are identified. 33 refs., 6 figs., 7 tabs.
