摘要: 用HZSM5,USY1,H-beta 3种不同类型的分子筛对木屑的快速热裂解气进行原位催化转化.研究了不同分子筛对积碳量、生物油产率、生物油组分分布的影响.实验结果表明,分子筛积碳量排序为:USY1>Hbeta>HZSM5.生物油产率在使用催化剂后有所降低,并且HZSM5产生的生物油产率最高.使用催化剂后生物油组分种类和含量都发生了明显的变化.3种分子筛中,HZSM5催化产生的烃类含量大大增加,轻质苯酚含量也明显增加,重质苯酚和糖类含量明显降低,催化效果显著.实验结果可供选择和改性催化剂时参考.

Abstract: Experiment in situ catalytic conversion of biomass fast pyrolysis vapors using HZSM5, USY1 and Hbeta zeolites was carried out. The influence of different zeolites on the carbon deposits yield, biooil yield and distribution of biooil components was investigated. According to the results, the amount of carbon deposits produced on the catalysts is as follows:USY1>Hbeta>HZSM5. After the employment of zeolite catalysts, the biooil yield decreased to some extent with HZSM5 generating the highest biooil yield. Besides, the variety of biooil components and their contents underwent an evident change. Among three different zeolites, HZSM5 displayed a superior catalytic performance, which is demonstrated by a substantial increase in hydrocarbons and an obvious increase in light phenols but a great decrease in heavy phenols and sugars. The results can provide some guide and reference for future selection of catalysts and further modification.
