The Cu-Y zeolite supported on silicon carbide for the vapor phase oxidative carbonylation of methanol to dimethyl carbonate was investigated. The nitrogen adsorption-desorption isotherms showed the modifications in term of specific surface area resulting from the zeolite coverage of the beta -SiC support. A beta -SiC supported Cu exchanged Y zeolite composite catalyst was successfully prepared and used for the gas phase oxidative carbonylation of methanol to dimethyl carbonate. The use of beta SiC probably allowed a real chemical binding between the zeolite and the support surface to occur, by simultaneous anchorage and crystallization of the zeolite. It resulted in the absence of any detrimental zeolite loss compared with a post-synthesis deposition of zeolite crystals.
