    摘要： The object of the present invention is to provide a catalyst regeneration process which can improve catalyst selectivity. A first aspect of the invention is characterized in that a spent catalyst from a reactor is introduced into a first fluidized bed regenerator and contacted with an oxygen-containing gas stream and optional steam to carry out a coke combustion reaction, wherein the resultant mixture of the partially regenerated catalyst and flue gas is introduced into a second fluidized bed regenerator and contacted with steam and an optional oxygen-containing gas stream to carry out a further regeneration reaction, and then the regenerated catalyst is introduced into the reactor. A second aspect of the invention is characterized in that a spent catalyst from a reactor is introduced into a fluidized dense bed regenerator and contacted with an oxygen-containing gas stream and steam to carry out a coke combustion reaction, and then the regenerated catalyst is introduced into the reactor. The inventive processes result in a more uniform distribution of the regenerated catalyst activity; due to the exposure of the catalyst to a low temperature for a long time, a part of the heavy metals are buried by the matrix and the remaining are passivated. Thereby dry gas and coke yields decrease sharply when hydrocarbons are subjected to a catalytic cracking reaction on the regenerated catalyst.

The first component is composed of at least one of zeolites selected from a group consisting of proton-type zeolites and ammonium type zeolites. The second component is composed of at least one of alkaline-earth metal compounds. The third component is composed of at least one selected from a group consisting of aluminum oxides, aluminum hydroxides, silicon oxides, silicon hydroxides, and clay minerals. The first component has a molar ratio of Si/Al of 10 or more and 300 or less. Content of the second component relative to the first component is 0.3 mass % or more and less than 10 mass % as alkaline-earth metal. Content of the third component relative to the first component is 15 mass % or more and 200 mass % or less.
