玉米秸秆炭和木屑炭催化裂解焦油的试验研究
Experimental Study on Catalytic Cracking of Tar with Corn Stalk Charcoal and Sawdust Charcoal
摘要
Abstract
In view of the adverse effects of tar produced in the process of biomass thermochemical conversion, the catalytic cracking method was used to reduce the coke into small molecular fuel gas, so as to achieve the double effects, reduce tar content and increase the low heating value of the producer gas. In this study, corn stalk charcoal and sawdust carbon obtained from slow pyrolysis at 500 ℃ were used as catalysts to study the catalytic cracking effect of tar. The results showed that two kinds of catalysts have good catalytic performance on tar cracking in all runs. As the cracking temperature increased, the content of H2 in the gas increased gradually, the content of CO, CH4, C2H4 and C2H6 were reduced gradually, and the low heating value of the cracking gas density decreased gradually. On comparison,the performance of sawdust charcoal on tar catalytic cracking is better than that of corn straw charcoal. The gas production rate of the cracking was increased with the cracking temperature increased when the cracking reaction temperature was 1000℃that corn straw charcoal and charcoal were used as catalysts, the gas production rate were 91.98％ and 94.11％, respectively. Finally, corn straw charcoal and sawdust charcoal both had good catalytic performance for tar, and also provided carbon source for catalytic cracking reaction.关键词
