Title:
PROCESS FOR PRODUCING CONJUGATED DIOLEFIN
Document Type and Number:
WIPO Patent Application WO/2014/061711
Kind Code:
A1
Abstract:
This process for producing a conjugated diolefin has the following configuration. A C4 or higher monoolefin is fed through monoolefin supply nozzles disposed at n positions (n=1, 2, ··, n). At least 50% of the total amount of an oxygen-containing gas is supplied through an oxygen-containing-gas supply nozzle located at the bottom of the fluidized-bed reactor. The C4 or higher monoolefin is fed through the monoolefin supply nozzles, which are located at distances of a1, a2, ···, and an from the oxygen-containing-gas supply nozzle, respectively in proportions of b1, b2, ···, and bn (b1+b2+··+bn=1). The arithmetic mean value which is represented by the following equation and is obtained from the distances and the proportions is 100 mm or more. Arithmetic mean value = a1*b1+a2*b2+··+an*bn
