ABSTRACT:
A disproportionation catalyst for olefins and a process for disproportionation of olefins using said catalyst are disclosed. The catalyst is a mixture of one part by weight of a first catalyst component comprising silica gel carrying thereon a tungsten oxide or its precursor and a Group I metal oxide or a compound convertible to Group I metal oxide; and 8-75 parts by weight of a second catalyst component which is alumina having a specific surface area of 20-120 m.sup.2 /g, and preferably carrying thereon a Group I or Group III metal oxide or a compound convertible to such an oxide. It exhibits a remarkably extended life of disporportionation activity and is thus applicable to the industrial use. The catalyst, therefore, can produce industrially useful compounds at a low cost by the application of the olefin disproportionation.
