摘要
Abstract
2-hydroxytetrahydrofuran(2-HTHF)is an important fine chemical material.The key to 2-HTHF production via hydroisomerization of cis-1,4-butenediol(cis-BED)lies in constructing the bifunctional catalyst with controllable metal center and acid strength.A series of Ni/WO3-ZrO2 bifunctional catalysts were prepared by incipient wetness impregnation method and their structures were characterized by NH3-TPD,XPS,XRD,etc.The effects of reduction temperatures,reduction time,loading amounts of Ni and WO3 and dispersions of Ni and WO3 on the structures and catalytic performances of catalysts were investigated.Additionally,the kinetics of the cis-BED hydroisomerization reaction over the optimal catalyst under specified conditions were studied.The results show that under the conditions of catalyst dosage of 0.2 g,reaction temperature of 200℃,H2 pressure of 0.4 MPa and gas hourly space velocity of 37.8 L/(g·h),10%Ni/20%WO3-ZrO2-HT(loading amounts of Ni and WO3 are 10%and 20%,respectively)obtained by reducing at 600℃for 2 h exhibits the best catalytic performance with cis-BED conversion rate of 67.9%and 2-HTHF selectivity of 30.1%,respectively.The established reaction network and kinetic model can effectively describ the cis-BED hydroisomerization process catalyzed by 10%Ni/20%WO3-ZrO2-HT,revealing that the primary pathway for 2-HTHF formation involves the isomerization of cis-BED to trans-1,4-butenediol,follows by its further conversion to 2-HTHF.关键词
