The apparatus includes a reactor, a combined gross separator and catalyst stripping vessel, and a disengaging vessel. The combined vessel is positioned to quickly separate catalyst from reactor products, reduce catalytic overcracking and strip volatile hydrocarbon from coked catalyst in one unitary vessel. The disengager is designed to dampen the flow of grossly separated hydrocarbon, substantially separate catalyst fines from the grossly separated hydrocarbon, and convey the catalyst fines to the combined gross separation and catalyst stripping vessel.Field of SearchIncluding means to strip reaction mass from, or to regenerate, the particulate matter (including fluidized bed regenerators, per se)And means providing flow of particulate matter into or out of reaction chamber And means mechanically separating and removing particulate bed material from fluid effluent Means injecting internal quench stream into reaction stream downstream of reaction stage Transfer line type reaction chamber With contact material regenerating means, per se, or combined with reactor With liquid present Plural reaction beds Sequentially arranged With heat exchange means affecting reaction chamber or reactants located therein Baffle intermediate concentrate collector zone and gas outlet conduit Tangential gas inlet opening in casing Separation of entrained fines from effluents Solids transferring | |
