The Institute of Gas Technology, Chicago, IL, is conducting research on biomass characterization, handling, devolatilization, and char gasification to develop a single-stage, pressurized, oxygen/air blown, fluidized-bed gasifier. Characterization of a wide variety of biomass species showed insignificant differences in proximate and ultimate analysis when expressed on a dry, ash-free basis. In general, the density of biomass is greater than that of its char, which requires special considerations in gasifier design. Ash fusion temperatures were significantly greater than the anticipated average gasifier temperature. It is possible to drive away the film and adsorbed moisture and dry biomass to about 6%, which may be desirable for some gasification strategies. The fluidization data obtained with biomass char mixed with sand or alumina are useful for gasifier design and operation. Data were also obtained to determine the effect of process variables on reaction rates and product yields during biomass devolatilization and char gasification. Based on these investigations, a 455 kg/h process research unit was constructed for operation at 2.17 MPa and 1089 K.
