    摘要: Disclosed is a process for controlling combustion in a fluid catalytic cracking regenerator. More specifically, afterburning which occurs during the combustion process is controlled by adjusting oxygen concentration in at least one of two combustion streams which is injected into a fluid catalytic cracking regenerator. Preferably, the combustion streams used in the invention are asymmetrically injected into a dense phase catalyst bed within the regenerator.

    摘要: A filter system for use in a three-phase slurry reactor is provided. The filter system comprises one or more bundles of a plurality of filter elements for separating liquid from a mixture of liquid and solids contained in the reactor. Each filter bundle is connected to a product transfer conduit transporting separated liquid to a location outside of and downstream from the reactor. The transfer conduit is provided with means for backflushing the filter bundle and guard filter means.

    摘要: The invention relates to a process for maintaining heat balance in a fluidized bed catalytic cracking unit. More specifically, the invention relates to a combustion control method capable of maintaining or restoring heat balance by conducting, under appropriate conditions, fuel and an oxygen-containing gas to a transfer line. The transfer line conducts effluent including spent catalyst and combustion products to the unit's catalyst regeneration zone.

    摘要: The invention is related to a catalyst and a process for selectively producing light (i.e., C2-C4) olefins from a catalytically cracked or thermally cracked naphtha stream. The naphtha stream is contacted with a catalyst containing from about 10 to 50 wt. % of a crystalline zeolite having an average pore diameter less than about 0.7 nanometers at reaction conditions. The catalysts do not require steam activation.

    摘要: This invention is related to a catalytically cracked or thermally cracked naphtha stream. The naphtha stream is contacted with a catalyst containing from about 10 to 50 wt. % of a crystalline zeolite having an average pore diameter less than about 0.7 nanometers at reaction conditions which include temperatures from about 500° C. to about 650° C. and a hydrocarbon partial pressure from about 10 to 40 psia. The resulting product is a high octane naphtha.
