The activity of nonfused methanol dissociation catalysts containing copper and optionally chromium, magnesium, calcium, barium, strontium, manganese, molybdenum, ruthenium and palladium can be improved by the incorporation of 0.1 to 20 weight percent amorphous silica.

Methanol dissociation catalysts

Process for the regeneration of deactivated copper-containing catalysts used in methanol or methyl formate dissociation reactions or in the steam reforming of methanol by first oxidizing then reducing the copper component of the copper-containing catalyst.

Regeneration of methanol dissociation catalysts

An improvement process for the preparation of copper-containing methanol dissociation catalysts by precipitation of a copper-containing catalyst precursor, calcination, and reduction of the precursor, the improvement comprising conducting the calcination of the precursor in an atmosphere of CO.sub.2.
