The present development is a catalyst for use in water gas shift processes, a method for making the catalyst and a method of using the catalyst. The catalyst is composed of iron oxide, copper oxide, zinc oxide, alumina, and optionally, potassium oxide, and is produced using a hydrothermal synthesis process. The catalyst demonstrates surprising activity for conversion of carbon monoxide under high to moderate temperature shift reaction conditions.

Iron-based water gas shift catalyst

A method is described for the manufacture of hydrotalcites by using at least one compound of a bivalent metal (Component A) and at least one compound of a trivalent metal (Component B), wherein at least one of these components is not used in the form of a solution, characterized in that The hydrotalcite precursors and/or fine-particle crystalline hydrotalcites which can be obtained by using the method in accordance with this present invention may be used in particular as catalysts or catalyst carriers or as nanocomposite filling agents or co-stabilizers in a polymer matrix.

A strontium-doped, calcium-alumina nickel supported reforming catalyst is useful for reforming reactions when it is desired to generate a low H/CO ratio synthesis gas and to reduce coking. The catalyst can generate a synthesis gas having a H/CO ratio of less than about 2.3. The catalyst includes alumina, from about 0.3 wt. % to about 35 wt. % of calcium oxide, from about 0.1 wl % to about 35 wt. % of a strontium promoter, and about 0.5 wt. % to about 30 wt. % nickel. The support is prepared by a method wherein the calcium oxide is combined with the alumina to form aluminum-rich calcium aluminates.

Nickel on strontium-doped calcium aluminate catalyst for reforming

A promoted calcium-alumina supported reforming catalyst that is particularly useful for reforming reactions where low H/CO ratio synthesis gas, such as less than 2.3 is generated directly is disclosed. The catalyst comprises from about 25 wt % to about 98 wt % alumina, from about 0.5 wt % to about 35 wt % calcium oxide, from about 0.01 wt % to about 35 wt % of a promoter, and from about 0.05 wt % to about 30 wt % of an active metal. The promoter is selected from the group consisting of titanium, zirconium, yttrium, niobium, elements of the lanthanum-series, such as, without limitation, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, ytterbium, and combinations thereof. The active metal is selected from the group consisting of nickel, cobalt, rhodium, ruthenium, palladium, platinum, iridium and combinations thereof as active metal, wherein the calcium oxide is combined with the alumina to form aluminum-rich calcium aluminates.
