Title:
PROCESS FOR PRODUCTION OF PROPYLENE AND AROMATIC HYDROCARBON, AND APPARATUS FOR THE PROCESS
Document Type and Number:
WIPO Patent Application WO/2007/080957
Kind Code:
A1
Abstract:
Disclosed is an improved process for production of propylene and an aromatic hydrocarbon
from a hydrocarbon raw material containing an olefin having 4 to 12 carbon atoms
by using a catalyst containing a middle-pore zeolite, wherein the yields of the
both products can be varied in a simple manner and the products can be produced
stably and with good efficiency. The process comprises: a propylene production
step for removing a hydrocarbon component having 4 or more carbon atoms from a
reaction mixture by using a specific zeolite catalyst and, if required, recycling
a part of the hydrocarbon component without any modification; and an aromatic
hydrocarbon production step wherein the entire or a part of the hydrocarbon component
having 4 or more carbon atoms is used as a starting material.
