Abstract
A catalyst which comprises nickel and/or cobalt supported on a support that includes a mixed oxide containing metals, such as aluminum, zirconium, lanthanum, magnesium, cerium, calcium, and yttrium. Such catalysts are useful for converting carbon dioxide to carbon monoxide, and for converting methane to hydrogen.
Claims37
A catalyst, comprising:
- (a) at least one catalytic metal, wherein said at least one catalytic metal is selected from the group consisting of nickel, cobalt, and a combination of nickel and cobalt;
- and
- (b) a support including a mixed oxide containing at least three metals, wherein said at least three metals are selected from the group consisting of aluminum, zirconium, lanthanum, magnesium, cerium, calcium, and yttrium, with the provisos that, when said support contains only three metals, said three metals are not aluminum, lanthanum, and magnesium, and when said support contains only four metals, such four metals are not cerium, lanthanum, potassium, and calcium.
A process for converting a feedstock comprising carbon dioxide and methane to synthesis gas, comprising:
- (a) heating said feedstock to a temperature of from about 650° C. to about 950° C. and at a pressure of up to 100 psi in the presence of a catalyst, wherein said catalyst comprises nickel supported on a support including a mixed oxide containing two or more metals, and said catalyst having a surface area of from about 140 m2/g to about 250 m2/g;
- and
- (b) recovering a product comprising synthesis gas.
