Title:
PROPYLENE PRODUCTION PROCESS AND PROPYLENE PRODUCTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2008/029631
Kind Code:
A1
Abstract:
Disclosed is a process for producing propylene, which comprises supplying a
feed gas containing dimethyl ether and/or methanol and a C4-olefin and/or a C5-olefin
to a reactor to allow these ingredients to react with each other in the presence
of a catalyst, wherein the feed gas is introduced into the reactor at a (the C4-olefin
and the C5-olefin)/(dimethyl ether and methanol) ratio of 0.25 to 7.5 inclusive
by mole in terms of the number of carbons, and the feed gas is contacted with the
catalyst at a temperature ranging from 350 to 600˚C inclusive. Also disclosed
is a propylene production apparatus, which comprises a hydrogenation reactor
for partially hydrogenating an alkyne and/or a diene contained in a C4-hydrocarbon
and/or a C5-hydrocarbon to convert the alkyne and/or the diene into an olefin
having one double bond; a reactor for reacting a feed gas containing the C4-hydrocarbon
and/or the C5-hydrocarbon and dimethyl ether and/or methanol in the presence
of a catalyst; and a separator for separating propylene from the resulting reaction
product.
