Title:

METHOD AND DEVICE FOR MANUFACTURING PROPENE AND C4 HYDROCARBON

Document Type and Number:

WIPO Patent Application WO/2018/072142

Kind Code:

A1

Abstract:

The present invention relates to a method and device for manufacturing, using an oxygen-containing compound, propene and a C4 hydrocarbon. The primary feature of the method is returning, by using a reactor feed distributor at a bottom-most portion of a fast fluidized-bed reactor, at least 70 weight percent of the light fraction of a generated product to a dense phase area of the fast fluidized-bed reactor. An alkylation reaction occurs, under the effect of a catalyst, between ethene and the oxygen-containing compound to generate products including propene and the like. A product comprising at least 80 weight percent of a C5 or higher hydrocarbon is recycled to a catalytic cracking enhancement pipe to allow a cracking reaction to take place and to generate a product comprising propene or a C4 hydrocarbon and the product then enters a dilute phase area of the fast fluidized-bed reactor. The method and device provided by the invention increases ethene alkylation reaction rates and unit volume production capacity of a reactor.
