摘要：

Continuous steam gasification of biomass is carried out in a fluidized bed reactor with the utilization of 10 wt% Fe/olivine catalyst. The volume composition of the product gas is analyzed by means of IR, UV and TCD for online detection of CO, CO2, CH4, H-2, NH3 and H2S. The results obtained have been evaluated with reference to a blank test (olivine bed inventory) performed with the same experimental rig: when 10 wt% Fe/olivine is utilized in the gasifier, the gas yield increases on average by 40% and the hydrogen yield by 88%. Correspondingly, the methane content in the syngas is reduced by 16% and tar production per kg of dry ash free (daf) biomass by 46%. 10 wt% Fe/olivine characterization after test shows that the catalyst is fairly stable.
