摘要/Abstract

摘要： 以谷壳作为生物质研究对象，在石英管反应器中研究了基于CO₂原位捕集的谷壳热解制H₂，考察了不同温度、不同的CO₂捕集剂（CaO）配比对其热解的产气量、气体中H₂的体积分数的影响。实验结果表明，谷壳热解的产气量随温度的升高而增大，当反应温度在800℃时有最大产气量340mL/g；捕集剂CaO的添加通过原位吸收CO₂促进相关反应向生成氢气的方向移动。在600℃，不同比例CaO下CO₂体积分数都保持在22%左右，谷壳热解产生的气体中H₂的体积分数为14%~26%；在700℃，当CaO与生物质质量比为1：4时，添加CaO捕集剂能够较好地捕集CO₂，有效提高H₂的体积分数，此时获得较高的H₂产率41%，较低的CO₂体积分数16%，CaO的捕集率为64%；GC-MS表征分析发现，CaO在800℃的温度下对热解过程中产生的焦油有部分催化裂解效果。

Abstract: Using ricehusk as raw materials,CaO as a capture agent,the change of combustible gases in different temperature and different proportion of capture agent in-situ CO₂ capture was investigated. The results showed that the pyrolysis gas production was significantly affected by temperatures,and there was maximum gas production of 340mL/g at 800℃. CaO sorbents promoted the reaction towards forming more hydrogen by in-situ CO₂ capture. At 600℃,with CO₂ concentration at 22%,the CO₂ capture had nothing to do with CaO proportion. At CaO:biomass=1:4 in 700℃,the higher H₂ yield 41% and the lower CO₂ yield 16% were abtained. And the CO₂ capture efficency was 64%. The GC-MS analysis showed that CaO played the role of catalytic cracking instead of temperature.
