摘要
生物质炭水蒸气气化制得的高热值富氢燃气是一种高效、环保的生物质能利用技术.为快速、科学地获得生物质炭的气化规律和最佳参数,本文选取了两种典型的农林废弃物稻草秸秆和松木屑为原材料,运用可提供理论依据的Aspen plus软件对原材料进行热解和水蒸气气化过程模拟,并结合自行搭建的热解、气化实验平台,以原材料为研究对象,对模拟结果进行了实验验证.综合结果表明:气化温度为800℃,S/C为4时,松木屑和稻草秸秆产生的H_2的体积分数分别达到最大值,为59.8%,59.5%,低位热值分别为13.8,13.5 MJ/Nm^3,松木屑的氧含量低于稻草秸秆,可获得更多的富氢、高热值气体.
The high calorific value and hydrogen rich gas produced by gasification of biomass carbon is a kind of high efficiency and environmental protection technology. In order to obtain the gasification law and the optimal parameters of biomass carbon, two kinds of typical agricultural and forestry waste（ straw and pine sawdust） were selected as raw materials, and the process of pyrolysis and steam gasification was simulated using Aspen plus to provide a theoretical basis for the research. Based on the experimental platform of pyrolysis and gasification, taking the raw materials as the research object, some experiments were carried out to verify the simulation result. It turned out that while gasification temperature is 800 and S/C is 4, rice straw and sawdust of pine could produce high volume fraction of H2 59.8%, 59.5%, respectively, and the low calorific value of rice straw and pine sawdust is 13.8 and 13.5 MJ/Nm^3 ,respectively. It was also found that the oxygen content of rice straw is lower than that of pine sawdust, obtaining more gas of rich hydrogen and high heat value.
