Abstract

original image

Propylene from methane: The transformation of methane to propylene has been realized in a two-step route via CH3Cl or CH3Br. CeO2 serves as an efficient and stable catalyst for the oxidative chlorination and bromination of methane to CH3Cl and CH3Br. In the second step, a modified zeolite is highly a selective and stable catalyst for the conversion of CH3Cl or CH3Br into propylene.
