Propylene production by co-reaction of ethylene and chloromethane over SAPO-34
The co-reaction of chloromethane and ethylene was studied over H-SAPO-34 catalyst. Higher propylene selectivity and higher chloromethane conversion than those in the case of sole chloromethane or ethylene feed were observed. The effect of co-feeding ethylene with chloromethane on the shortening of induction period was also investigated. It is suggested that the methylation of ethylene plays an important role in the co-reaction system. The investigation of reaction conditions on reactant conversion and product distribution showed that the conversions of the reactants increased with increasing contact time and reaction temperature, and that the selectivity to propylene increased with decreasing contact time.
