Abstract
A process for the preparation of water gas shift catalyst is described. The process includes mixing a copper salt and a zinc salt with an aluminum component in a solution, precipitating a precipitate from the solution, drying an forming the precipitate into the water gas shift catalyst. In an alternate process the aluminum component is prepared separately from the solution of the copper salt and the zinc salt prior to the mixing of the components. After the components are mixed a precipitate is precipitated from the solution, the precipitate is dried and formed into the catalyst.

A process for the preparation of a water gas shift catalyst comprising
- mixing a copper salt and a zinc salt with an aluminum component in an aqueous solution to form a catalyst precursor, wherein the aluminum component is prepared by mixing an aluminum salt with alumina, wherein from about 30 to about 95 percent by weight of the aluminum component comprises alumina, and wherein from about 1% to about 60% of the aluminum present in the catalyst precursor is in the form of hydrotalcite;
- precipitating a precipitate from the solution with a precipitating agent;
- and
- drying, and forming the precipitate into the catalyst.
