FORMED COMPOSITIONS

摘要

A process is disclosed for the preparation of formed Group IVB metal oxide compositions suitable for use as catalyst supports which comprises: A) preparing a paste comprising (i) one or more calcined Group IVB metal oxides, (ii) at least one solvent and (iii) at least one acid; B) forming a shaped particle from said paste; and C) drying and calcining said shaped particle. Also disclosed are formed compositions prepared by the foregoing process and catalysts where the formed compositions incorporate therein or have supported thereon catalytically active materials.
