Abstract: A petroleum hydrocarbon multi-stage fluid catalytic reaction method and reactor are described. The method implements a sectional multi-stage reaction in one reactor and comprises primary-stage and secondary-stage catalytic cracking reactions of feedstock oil and primary-stage and secondary-stage catalytic cracking reactions of light hydrocarbons and/or cycle oil, which occur in different reaction regions of the reactor. The primary-stage reaction of the light hydrocarbon and/or circulation oil is carried out in an independent reaction region. The reactor comprises a first reaction section, a catalyst splitter, a third reaction section, a second reaction section and a settler.

Abstract: The present invention relates to the technical field of petroleum hydrocarbon catalytic conversion, referring to a multi-stage fluidized catalytic reaction process of petroleum hydrocarbon. In the present reaction process, multi-stage reaction takes place in the same reactor, including first order reaction and the second order reaction of FCC feedstock oil, cracking reaction process of light hydrocarbons and/or cycle oil. In the present process, catalyst replacement and two-stage relayed reaction takes place between the first and second order reaction of feedstock oil. Two-stage reaction of light hydrocarbons and/or cycle oil takes place too. These reactions take place in different region in the same one reactor. The first order reaction of light hydrocarbons and/or cycle oil takes place in independent region. In the present invention, catalytic cracking conversion of catalytic feedstock oil, light hydrocarbon and cycle oil takes place in respective reaction region and reaction condition.

Abstract: A regeneration method for catalytic cracking reaction, the method is applied in a catalytic reaction process of petroleum hydrocarbon materials, and the method comprises: feeding the regenerated and semi-regenerated catalyst from a regenerator separately into different positions of a reactor for reaction. A part of the semi-regenerated catalyst is firstly processed in a purification cooler for removing carried nitrogen, oxygen, carbon dioxide and impurity gases before being fed into the reactor. Spent catalyst or the purified and cooled semi-regenerated catalyst is fed into a catalyst mixing section of the reactor for controlling the temperature of the catalyst being contact with the oil material to be gasified, thereby achieving a three stage cycle of the catalyst in the reactor and a three stage control for the reaction outlets of the oil material gasification zone and the cracking reaction zone and the catalyst taking part in the reaction.
