Title:
PROCESS FOR THE OXYGEN FREE CONVERSION OF METHANE TO ETHYLENE ON ZEOLITE CATALYSTS
Document Type and Number:
WIPO Patent Application WO/2015/018807
Kind Code:
A3
Abstract:
The present invention relates to a process comprising the step of converting methane to ethene under non-oxidative conditions in the presence of a catalyst comprising (a) a zeolite with a largest pore opening which is larger than 8; (b) a metal whereas the metal (b) is loaded onto the zeolite (a); and whereas the zeolite (a) is selected from zeolites -with a maximum diameter of a sphere that can be included of 4.5 A or smaller and/or -with a maximum diameter of a sphere which can diffuse along a of 4.4 A or smaller and/or -with a maximum diameter of a sphere which can diffuse along b of 4.4 A or smaller and/or -with a maximum diameter of a sphere which can diffuse along c of 4.4 A or smaller. Zeolite (a) is preferably a RRO catalyst, in particular RUB-41.
