摘要
借助综合热分析仪和傅立叶红外联用技术(TG-FTIR),考察了HUSY、REY和HZSM-53种分子筛以及重油催化裂化催化剂MLC和馏分油催化裂解催化剂CIP对生物质催化热解的活性和选择性。研究结果表明,分子筛对生物质热解产物的脱氧活性顺序为:REY≈HUSY>HZSM-5,生成高辛烷值烃类的选择性顺序为:REY>HUSY≈HZSM-5;MLC催化剂和CIP催化剂都表现出较高的选择活性,前者的脱氧活性略高于后者;择形分子筛HZSM-5的引入对调整催化剂酸强度、提高催化转化选择性和抑制焦炭生成产生一定作用。
The TG integrated with FFIR was used to investigate the activities and seleetivities of HUSY, REY and HZSM- 5 zeolites, and furthermore, the heavy oil cracking catalyst MLC and distillate oil cracking catalyst CIP used in China refining industry. The research shows that REY zeolite has satisifing activity for deoxygenation and selectivity for High-Octane-Number-Hydrocarbons production. Both MLC and CIP catalyst show well HONH seleetivities, however, MLC catalyst shows better deoxygenating activity. The adoption of HZSM-5 can adjust catalyst acid strength, improve catalyst selectivity and inhabit the coke-deposition on catalyst pores as well.
