Document Type and Number:
WIPO Patent Application WO/2011/019037
Kind Code:
A1
Abstract:
Provided is a method for producing a catalyst in which a catalyst, which contains zeolite as the active ingredient and which has a reduced ethylene conversion rate following a reaction to produce propylene in which the catalyst was brought into contact with ethylene in a gas phase, is regenerated by being brought into contact with a gas which does not contain oxygen but does contain hydrogen at a hydrogen partial pressure of 0.01 MPa or greater by absolute pressure.
