Synthesis of nanoscale HZSM-5 zeolite and its application in alkylation, dehydration of bio-ethanol and upgrading of FCC gasoline

摘要

HZSM-5 zeolite catalyst has high activity and low deactivation tendency compared with other zeolites which is an important factor for the industrial application. Compared with microscale HZSM-5, nanoscale HZSM-5 has more pore openings, more accessible acid sites, larger external surface area and the secondary pores which increase the reaction activity and the ability to resist coking during many reactions [1,2]. In this paper, we summarize the recent studies on synthesis of nano-scale HZSM-5 and its application in many reactions in our group.
