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.
Claims21
A catalyst comprising a mixed oxide of magnesium and manganese, wherein the catalyst further comprises lithium and boron dopants and at least one doping element from groups 4, 9, 12, 13 or combinations thereof, wherein the catalyst comprises a C2 selectivity of greater than 50% and a methane conversion of greater than 20% when the catalyst is employed as a heterogeneous catalyst in the oxidative coupling of methane at a temperature of 750° C. or less.
A catalyst comprising a mixed oxide of manganese and tungsten, wherein the catalyst further comprises a sodium dopant and at least one doping element from groups 2, 16 or combinations thereof.
A catalyst comprising an oxide of a rare earth element, wherein the catalyst further comprises at least one doping element from groups 1-16, lanthanides, actinides or combinations thereof, wherein the catalyst comprises a C2 selectivity of greater than 50% and a methane conversion of greater than 20% when the catalyst is employed as a heterogenous catalyst in the oxidative coupling of methane at a temperature of 750° C. or less.
