Title:
OLEFIN PREPARATION METHOD USING CIRCULATING FLUIDIZED BED PROCESS
Document Type and Number:
WIPO Patent Application WO/2018/225952
Kind Code:
A1
Abstract:
The present invention relates to a circulating fluidized bed process for preparing olefin from a hydrocarbon material by means of a high-speed fluidized bed. Disclosed is a preferable process type for more efficiently increasing an olefin yield. According to the present invention, by means of using a catalyst, which enables a dehydrogenation reaction, and a high-speed fluidization regime in a circulating fluidized bed process, more sufficient volumetric ratio and distribution of the catalyst enabling a dehydrogenation reaction are provided, the yield of the olefin is efficiently increased and, particularly, excellent selectivity with respect to propylene can be maintained.
