In a fluidized catalytic cracking apparatus a mixture of hydrocarbon products and hydrocarbon catalyst particles is removed from a reactor riser (1) and introduced into a cyclone separator (2), wherein in order to strip the catalyst particles, primary steam is injected into the cyclone separator (2), and wherein, for additional stripping the catalyst particles are introduced into a stripper assembly (3) comprising at least two interconnected stripper vessels (4, 5) into which secondary steam is introduced.

Apparatus for separating hydrocarbon products from catalyst particles

Method for the production of hydrocarbon comprises contacting as feed low molecular weight oxygenated organic compounds with a zinc halide in the presence of certain high-boiling, low vapor pressure compounds having good solvency for the zinc halide.
