    摘要： The present invention relates to a catalytic conversion process for producing more diesel and propylene, comprising contacting the feedstock oil with a catalyst having a relatively homogeneous activity in a reactor, wherein the reaction temperature, weight hourly space velocity and weight ratio of the catalyst/feedstock oil are sufficient to obtain a reaction product containing from 12 to 60% by weight of a fluid catalytic cracking gas oil relative to the weight of the feedstock oil; the fluid catalytic cracking gas oil is fed into the fluid catalytic cracking gas oil treatment device for further processing. Catalytic cracking, hydrogenation, solvent extraction, hydrocracking and process for producing more diesel are organically combined together, and hydrocarbons such as alkanes, alkyl side chains in the feedstock for catalysis are selectively cracked and isomerized.

    摘要： A catalytic conversion process for increasing the cetane number barrel of diesel, in which contacting the feedstock oil with a catalytic cracking catalyst having a relatively homogeneous activity containing mainly the large pore zeolites in a catalytic conversion reactor, wherein the reaction temperature, residence time of oil vapors and weight ratio of the catalyst/feedstock oil are sufficient to obtain a reaction product containing from about 12 to about 60% by weight of a fluid catalytic cracking gas oil relative to the weight of the feedstock oil and containing a diesel; the reaction temperature ranges from about 420° C. to about 550° C.; the residence time of oil vapors ranges from about 0.1 to about 5 seconds; the weight ratio of the catalytic cracking catalyst/feedstock oil is about 1-about 10. The fluid catalytic cracking gas oil is fed into other unit for further treatment or is fed back to the initial catalytic conversion reactor. The process allows the maximum production of high cetane number diesel, the cracking catalyst having a coarse particle size distribution can further improve the selectivity of dry gas and coke, and can reduce the breaking tendency of the catalyst and the consumption of the catalyst.

    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.
