초록 ▼

C.sub.2 to C.sub.4 olefins are selectively produced from a gas oil or resid in a two stage process. The gas oil or resid is reacted in a first stage comprised of a fluid catalytic cracking unit wherein it is converted in the presence of conventional large pore zeolitic catalyst to reaction products, including a naphtha boiling range stream. The naphtha boiling range stream is introduced into a second stage comprised of a process unit containing a reaction zone, a stripping zone, a catalyst regeneration zone, and a fractionation zone. The naphtha feedstream is contacted in the reaction zone 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 ranging from about 500 to 650.degree. C. and a hydrocarbon partial pressure from about 10 to 40 psia. Vapor products are collected overhead and the catalyst particles are passed through the stripping zone on the way to the catalyst regeneration zone. Volatiles are stripped with steam in the stripping zone and the catalyst particles are sent to the catalyst regeneration zone where coke is burned from the catalyst, which is then recycled to the reaction zone.

[ What is claimed is:] [1.] A two stage process for selectively producing C.sub.2 to C.sub.4 olefins from a heavy hydrocarbonaceous feedstock, which process comprises:a) reacting said feedstock, in a first stage comprised of a fluid catalytic cracking unit wherein it is converted in the presence of a large pore zeolitic catalytic cracking catalyst having an average pore diameter greater than about 0.7 nm and having a crystalline tetrahedral framework oxide component to lower boiling reaction products;b) fractionating said lower boiling reaction products into various boiling point fractions, one of which is a naphtha boiling range fraction and one of which is a vapor fraction,c) reacting said naphtha boiling range fraction in a second reaction stage comprised of a process unit comprised of a reaction zone, a stripping zone, a catalyst regeneration zone, and a fractionation zone, wherein the naphtha boiling range fraction contains from about 10 to 30 wt. % paraffins and from about 15 to 70 wt. % olefins, and is contacted in the reaction zone with a catalyst containing from about 10 to 50 wt. % of a crystalline zeolite having an average pore diameter less than about 0.7 nm and silica to alumina molar ratio of less than about 75:1 at reaction conditions which include temperatures ranging from about 500 to 650.degree. C. and a hydrocarbon partial pressure from about 10 to 40 psia, and a catalyst to feed ratio, by weight of about 4 to 10, and wherein propylene comprises at least about 90 mol. % of the total C.sub.3 products;d) collecting the resulting vapor products overhead and passing catalyst particles through the stripping zone wherein volatiles are stripped with steam;e) passing the stripped catalyst particles to a regeneration zone where coke is burned from the catalyst; andf) recycling the hot regenerated catalyst particles to the reaction zone.
