Partial oxidation of methane with nitrous oxide forms synthesis gas over cobalt exchanged ZSM-5

摘要

Synthesis gas (CO + H2) is a versatile and significant resource. In this communication we show that cobalt loaded on ZSM-5 (Co-ZSM-5) catalyses the formation of synthesis gas from CH4, under partial oxidation conditions using N20 as oxidant. With O2 as oxidant over the same Co-ZSM-5 catalyst, cobalt on alumina and Fe-ZSM-5, only CO_x and H2O are formed. Isolated Co~(2+) sites in the ZSM-5 support are proposed as the active sites for H2 (synthesis gas) formation.
