Abstract

Especially physically stable metal oxide catalyst supports are prepared by suspending a metal oxide in a continuous phase, activating by fine dispersion, coagulation to a viscoelastic mass, shaping, drying, and calcining. The catalyst support thus prepared may be treated with catalytic agents to produce supported catalysts for olefin oxidation.
