Conversion of ethane and of propane to higher olefin hydrocarbons
It has become apparent during the past few months that results obtained in the oxidative coupling of methane cannot be extended to ethane and propane. Good selectivities and yields for the oxydehydrogenation to olefins can be obtained but production of higher hydrocarbons is small. The present report summarizes results of experiments using zeolite based catalysts and compares these with basic oxide catalysts. The oxydehydrogenation of ethane over zeolite based catalysts (H[sup [minus plus]] Na[sup [plus minus]], Ni[sup 2[plus minus]], Pt[sup 2[plus minus]], Ga[sup 3[plus minus]], and [V]-ZSM-5) and oxide catalysts (Li/MgO, Ca-Ni-K) was studied in the temperature range 450--600[degree]C. Selectivity to olefins close to 80% was achieved at 550[degree]C. Basic (Na-ZSM-5) and neutral (V-ZSM-5) zeolite catalysts were shown to be more active and selective for the oxydehydrogenation of ethane than oxide catalysts.
