摘要： The present invention relates to a catalytic conversion apparatus, characterized in that said apparatus comprises at least one feed oil cracking riser reactor, a dense bed reactor, a disengager, and a stripper, wherein said stripper locates below said dense bed reactor and communicates directly with the lower part of the dense bed reactor or through a fluid-communicating channel, the outlet of at least one of said riser reactor(s) communicates with the lower part of said dense bed reactor or any part of said fluid-communicating channel, the outlet of said dense bed reactor communicates with the inlet of a gas-solid separating apparatus located in said disengager through said disengager and/or through an optional transporting channel, the catalyst outlet of said disengager communicates with at least one position selected from the upper part of said stripper, any part of said fluid-communicating channel, and the lower part of said dense bed reactor, through at least one catalyst transporting channel. The catalytic conversion apparatus according to the present invention sets up at least one riser reactor and a dense bed reactor to carry out further cracking of the intermediate products, produced from the feed oil by the cracking reaction in the riser, in the dense bed reactor. Moreover, the spent catalysts discharged from the outlet of the dense bed reactor can be introduced into the stripper via a specific catalyst transporting channel, so as to maintain higher activity and temperature of the catalyst in the dense bed reactor and be advantageous to deeper cracking of the intermediate products in the dense bed reactor so as to produce more light olefins, particularly propylene.

A dense bed reactor which is separated from disengage, is employed to enforce further cracking hydrocarbon to light olefins, with low methane yield. Moreover, the spent catalysts discharged from the outlet of the dense bed reactor can be introduced into the stripper via a specific catalyst transporting channel, to maintain catalyst concentration in the dense bed reactor that can be advantageous to deeper cracking of the intermediate products to produce more light olefins, particularly propylene.
