Methane conversion over Sr~(2+)/La_2O_3 catalyst modified with nickel and copper

摘要

Methane transformation over Ni and Cu modified Sr~(2+)/La_2O_3 catalysts has been studied.These species favor formation of reducible mixed oxides and change the surface reactivity of the Sr~(2+)/La_2O_3 system,modifying the reaction mechanism.since Sr~(2+)/La_2O_3 favors methane oxidative coupling but with copper methane combustion is favored and nickel favors partial oxidation.
