Al源种类对微乳液法制备固体超强酸催化剂异构化性能的影响
Influence of aluminum species on the isomerization performance over solid superacid Pt-S2 O2-8/ZrO2-Al2 O3
摘要
Abstract
A series of Pt-S2 O2-8 /ZrO2-Al2 O3 catalysts were prepared by microemulsion method with pseudo-boehmite,γ-Al2O3, Al2O3 and Al(NO3)3·9H2O as aluminum source, respectively, and the resulting catalysts were characterized by XRD, FT-IR, BET, H2-TPR techniques. The influence of aluminum sources on the structure and acidic properties of the catalysts were investigated. The catalytic performance of the Pt-S2 O2-8 /ZrO2-Al2 O3 catalysts was studied using n-petane isomerization as a probe reaction. The results indicated that all the catalysts prepared with different source of aluminum can stabilize the tetrogonal ZrO2 phase and increase specific surface area of the catalysts. Except for pseudo-boehmite, the redox performance of catalysts prepared with other aluminum source were improved. The catalyst prepared with Al ( NO3 )3·9H2O as the aluminum source, which possessed the largest specific surface area and more superacid, exhibited the best isomerization performance. At a reaction temperature of 220℃, a pressure of 2. 0 MPa, a hydrogen/hydrocarbon mol ratio of 4∶1 and a WHSV of 1 . 0 h-1 , the isopentane yield reaches a maximum of 59 . 5%.关键词
