Abstract
A process for preparing a catalyst includes impregnating a metal oxide carrier with an aqueous solution to form an impregnated carrier; drying the impregnated carrier to form a dried, impregnated carrier; and heat-treating the dried, impregnated carrier in air to form the catalyst; wherein: the aqueous solution includes a copper salt; and from about 3 wt % to about 15 wt % of a C3-C6 multifunctional carboxylic acid; and the catalyst includes from about 5 wt % to about 50 wt % copper oxide.
Claims20
A catalyst precursor composition comprising:
- a metal oxide carrier impregnated with an aqueous solution, the aqueous solution consisting essentially of water, a copper salt, optionally a bismuth salt, optionally a precipitation agent and from about 1 wt % to about 15 wt % of a C3-C6 multifunctional carboxylic acid.
A catalyst for hydrogenation, dehydrogenation, hydrogenolysis, or ethynylation, the catalyst consisting essentially of from about 5 wt % to about 50 wt % copper oxide and optionally bismuth oxide, and wherein the catalyst is prepared by a process comprising:
- impregnating a metal oxide carrier with an aqueous solution to form an impregnated carrier;
- drying the impregnated carrier to form a dried, impregnated carrier;
- and
- heat-treating the dried, impregnated carrier in air to form the catalyst;
- wherein:
- the aqueous solution consists essentially of water, a copper salt, optionally a bismuth salt, and optionally a precipitation agent;
- and
- from about 1 wt % to about 15 wt % of a C3-C6 multifunctional carboxylic acid.
