摘要： 在温度为800、850、900和950 ℃,压力为0.1～0.6 MPa的条件下,考察了一定流量的水蒸气和松木屑反应产生合成气的气体组分和产量的变化规律。实验结果表明高温能够增加反应速率并且有利于产生富氢燃气,氢气的含量在气体中最高,超过了50 %;同时,随着温度增加,合成气中H2和CO的浓度逐渐增加,CO2和CH4的浓度逐渐减少。提高反应系统的压力,合成气气体的产量会增加而产生的焦油量减少, H2和CO2浓度出现增加趋势而CO和CH4的浓度出现减小趋势。

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
