Title:
シリカ-アルミナ触媒を用いたオレフィンのオリゴマー化方法
Document Type and Number:
Japanese Patent JP5537816
Kind Code:
B2
Abstract:
Oligomerization of olefinic hydrocarbon charge comprises contacting the charge with a catalyst comprising a silica-alumina, where mass content of silica is 5-95 wt.%, and the catalyst is prepared by a process comprising: mixing an aluminum compound partially soluble in acid medium with at least one silica compound totally soluble in the reaction mixture, which is a combination formed of at least one silica compound and aluminum compound, forming a solid precursor of the catalyst; and hydrothermal treatment of the solid from the mixing step by calcination in moist air for 4-7 hours.
