Abstract
An olefin oligomerization catalyst comprises at least one oxide selected from alumina and silica.cndot.alumina having a sulfate ion supported thereon. The amount of the sulfate ion contained in the catalyst is desirably in the range of 0.3 to 60% by weight based on the total weight of the alumina and/or silica.cndot.alumina and the sulfate ion. The olefin oligomerization catalyst can be readily prepared by bringing a sulfuric acid aqueous solution or an ammonium sulfate aqueous solution into contact with at least one compound selected from alumina, silica alumina and their precursors, followed by drying and calcining. Further, an olefin oligomerization catalyst comprises at least one oxide selected from alumina and silica.cndot.alumina on which a transition metal oxide is further supported in addition to the sulfate ion. By the use of the catalyst, a lower olefin produced in, for example, a petroleum refining process can be converted into an oligomer of high value added.
