Title:
PROCESS FOR PRODUCTION OF PROPYLENE
Document Type and Number:
WIPO Patent Application WO/2008/041561
Kind Code:
A1
Abstract:
Disclosed is a novel process for producing propylene by using ethylene and at least
one member selected from methanol and dimethyl ether as starting materials, which
can reduce the amount of unreacted ethylene to be recycled and has low equipment cost
and running cost. Specifically disclosed is a process for producing propylene by
using ethylene and at least one member selected from methanol and dimethyl ether
as starting materials, which comprises reacting ethylene and at least one member
selected from methanol and dimethyl ether under specific conditions to produce
a fluid containing an olefin having 4 or more carbon atoms, and then reacting at
least a part of the olefin having 4 or more carbon atoms contained in the fluid with
at least one member selected from methanol and dimethyl ether under specific
conditions, thereby producing propylene.
