摘要：

A lab-scale biomass entrained flow gasification system was used to test sawdust gasification in order to investigate the effects of reaction temperature and the mass ratio of oxygen to biomass on biomass gasification performance including gas composition, carbon conversion, products distribution and solid residue behavior. Results showed that H2 volume fraction increased and CO2 volume fraction decreased with the reaction temperature increasing; syn-gas composition in high temperature (1000-1400°C) reached above 80%. CH4 volume fraction increased firstly and then decreased with the reaction temperature increasing, at last CH4 volume fraction was very little at 1400°C. The liquid product mass fraction reached only about 8%-10% at 1400°C, which indicated that the tar content was very low. The carbon conversion rate increased to a maximum value 95% at 1400°C with the reaction temperature increasing; the high carbon conversion rate appeared between 600°C and 800°C. The gas product yield rate increased with the reaction temperature increasing and it reached to a maximum value 91% at 1400°C.
