Abstract
Metal oxide catalysts comprising various dopants are provided. The catalysts are useful as heterogenous catalysts in a variety of catalytic reactions, for example, the oxidative coupling of methane to C2 hydrocarbons such as ethane and ethylene. Related methods for use and manufacture of the same are also disclosed.
Claims15
A catalytic material comprising a support or carrier and a catalyst comprising the following formula:
- ABO3;
- wherein:
- A is an element from the lanthanides or group 2, 3 or 4 of the periodic table;
- B is an element from groups 4, 12 or 13 of the periodic table or Ce, Eu, Gd, Tb or Ho, and
- O is oxygen,
- the catalyst further comprising one or more dopant from any one of groups 2 or 3, and wherein the catalyst further comprises a methane conversion of greater than 20% and a C2 selectivity of greater than 50% when the catalyst is employed as a heterogeneous catalyst in the oxidative coupling of methane at a temperature ranging from about 550° C. to about 750° C., and provided that A and B are not the same.
