摘要

摘要: 利用固定床反应器对生物油的水蒸气非催化气化性能进行了实验研究,考察了温度和水蒸气的加入量对气化过程的影响,对气化所得粗合成气的组成分布进行了分析。结果表明,升高温度有利于生物油向合成气转化,1 200 ℃时,生物油的碳转化率可达97.8%,合成气有效成分(H₂+CO)的产率可达77%,其中H₂/CO摩尔比为1.19;水蒸气的加入可以提高合成气中的H₂/CO摩尔比,当S/C(水碳比)=4时,合成气中的H₂/CO摩尔比可达3.69,与此同时,水蒸气的加入不利于合成气有效成分产率的提高;生物油气化所得气体为中热值气体。

Abstract: The experiment on the non-catalytic steam gasification of bio-oil was carried out in a lab-scale fixed bed reactor. The influence of operating parameters such as the temperature and the mol ratio of steam to carbon (S/C) on the gas yield and composition was investigated. The results show that increasing temperature can enhance the conversion of bio-oil to syngas; the carbon conversion of bio-oil can be as high as 97.8% at 1 200 ℃, and the proportion of effective gas component (H₂+CO) in the product gas is nearly 77% with a mol ratio of H₂/CO=1.19. The mol ratio of H₂/CO increases with an increase of S/C mol ratio, and reaches up to 3.69 at S/C=4. However, the addition of steam does not favor the increase of the composition of effective syngas. The product gas from steam gasification has a medium heating value.
