Title:
METHOD FOR PRODUCING OLEFINS
Document Type and Number:
WIPO Patent Application WO/2006/093058
Kind Code:
A1
Abstract:
Provided is a method for producing olefins by a metathesis reaction with a catalyst improved in reactivity at a practically low temperature. The method for producing olefins uses a compound containing at least one metal element of the metals belonging to Ia Group (alkali metal), IIa Group (alkaline earth metal), IIb Group and IIIa Group as a co-catalyst, in a metathesis reaction of olefin using a catalyst containing a metal element such as tungsten, molybdenum or rhenium. Furthermore, by a hydrogen gas co-existent with the above reaction materials, the progress of the metathesis reaction may be allowed in a practically low temperature region at a satisfactory reaction rate.
