Abstract: Evolutionary behavior of gas chemical composition and yield had been examined for pine sawdust at four different temperatures of 800, 850, 900 and 950 ℃ under pressures range of 0.1-0.6 MPa, using steam as the gasification agent at a constant flow rate. The results showed that high temperature could accelerate reactions rate and tend to generate hydrogen-rich gas product. Hydrogen is mast aboundant gas composition during sawdust gasification, which content reached more than 50%. Meanwhile, elevated temperature led to an increasing amount of H2 and CO while a decreasing amount of CO2 and CH4. The results also showed that the overall output of product increased with elevated pressure gas while the tar decreased. The concentration of H2 and CO2 increased while CO and CH4 decreased with gasification pressure gradually rising.

Key words: pine sawdust, pressurized gasification, steam, gas composition
