CATALYSTS

摘要

A process for preparing a catalyst precursor includes forming a slurry of particles of an insoluble metal compound, where the metal of the insoluble metal compound is an active catalyst component, with particles and/or one or more bodies of a pre-shaped catalyst support in a carrier liquid. The particles of the insoluble metal compound are thus contacted with the particles and/or the one or more bodies of the pre-shaped catalyst support. A treated catalyst support is thereby produced. Carrier liquid is removed from the slurry to obtain a dried treated catalyst support, which either directly constitutes the catalyst precursor, or is optionally calcined to obtain the catalyst precursor.
