Abstract

An integrated catalyst can be used in an olefin disproportionation reaction. The integrated catalyst contains a plurality of different integrated active phases. The relative positions among different active phases remain substantially unchanged during the olefin disproportionation reaction. The effective distance between respective bisecting planes of two adjacent different active phases is 0.5-5 mm, preferably 1-3 mm.
