| 摘 要： | 目的]研究生物质焦油在不同气氛下气化温度对生物质焦油产气组分与产气特性的影响。方法]采用实验室规模的固定床反应器研究N2、水蒸气和CO2气氛下,生物质焦油在500、600、700、800、900℃时裂解产气组成及其特性。结果]在3种反应气氛下,H2、CO和CH4的含量及气体特性均随温度的升高而增加。水蒸气的介入能够明显促进产品气中H2和CO的含量,当温度达到800℃时,H2浓度达到最大值45.22%。CO2浓度过高对生物质焦油的气化反应有明显的抑制作用。结论]为生物质焦油的气化和生物质的高质化利用提供了重要的理论依据。

| Abstract: | Objective] The effect of the gasification temperature under the different atmospheres on the component of syngas from tar and the characteristics of syngas formation was researched.Method] The component and the characteristics of the syngas produced from the gasification of tar through the biomass pyrolysis at different temperature of 500,600,700,800 or 900 ℃ was studied in a fixed bed reactor of different agents: N2,water atmospheres and CO2 in Lab.Results] Under the reactor of three agents: N2,water atmospheres and CO2,the concentration and gasification characteristics of H2,CO and CH4 was improved with the temperature-increasing.The introduction of water steam would obviously improve the concentration of H2 and CO in the produced gas and the concentration of H2 would reach the maximum(45.22%) at 800 ℃.The high concentration of carbon dioxide had great inhibition effect on the gasification of tar.Conclusion] The important theoretic reference for the utilization of the gasification of tar and its good-quality was provided. |
