    摘要: A catalytic conversion process for producing light olefins with a high yield from petroleum hydrocarbons, which comprises the steps of contacting a pre-heated petroleum hydrocarbons feedstock with a catalyst which comprises phosphorus and transition metal modified silica rich zeolite having a structure of pentasil in a riser or a fluidized bed reactor, and converting under the catalytic conversion conditions to produce reaction effluent and a spent catalyst, separating the resulted reaction effluent and spent catalyst, further separating said reaction effluent into liquid products and gaseous products comprising ethylene and propylene; stripping the spent catalyst by steam; regenerating the stripped catalyst by contacting the spent catalyst with oxygen-containing gas and burning off coke; and recycling the regenerated catalyst to reactor for reuse.

    摘要: A process for catalytic conversion of hydrocarbon feedstock to produce isobutane and isoparaffin-enriched gasoline which comprises two different reactions, the preheated feedstock is contacted with hot regenerated catalyst in the lower part of a reactor with the result that catalytic cracking reaction takes place, and the mixture of vapors and the coke deposited catalyst are up-flowed and enter into a suitable reaction environment with the result that isomerization and hydrogen transfer reaction take place. The produced LPG has an isobutane content of about 20 wt % to about 40 wt % and the produced gasoline contains isoparaffin content of about 30 wt % to about 45 wt % and olefin content of less than 30 wt %. RON and MON of the gasoline are 90˜93 and 80˜84 respectively.
