通过实验方法研究在蒸汽环境下生物质炭对生物质热解焦油的催化重整特性。通过分析蒸汽加入量和加入方式的变化可知:在蒸汽条件下,生物质炭对焦油催化裂解效果显著,焦油转化率最高可达96.1%。通过对实验条件下焦油转化率、裂解产物、裂解气体积分数的分析可知,生物质炭和蒸汽可促进热解产物中的可凝结相转化为不可凝结的气体,且使气体组分体积分数发生变化。蒸汽以不同比例、不同位置输入裂解器中,有利于焦油的催化裂解和提高燃气的热值。
The catalytic reforming of biomass pyrolysis tar was studied by means of experimental methods under the steam environment. By analyzing the amount of steam added and the change of adding method, we can see that under the condition of steam, the catalytic effect of biomass carbon on tar is remarkable, and the highest tar conversion rate is 96.1%. Through the analysis of tar conversion, pyrolysis products and pyrolysis gas under the experimental conditions, biomass carbon and steam can promote the conversion of condensable phase of pyrolysis products into non-condensable gas, Change. Steam in different proportions, different positions into the cracker, is conducive to catalytic cracking of tar and increase the calorific value of gas.
