Title:
COMPOSITE OXIDE CONTAINING TUNGSTATE NANOCLUSTERS, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/060628
Kind Code:
A1
Abstract:
A cocatalyst in an oxidative coupling of methane (OCM) reaction and a catalyst composition thereof, as well as an application in a catalytic chemical reaction, relating to the field of catalysts. A composite oxide containing tungstate nanoclusters, the composite oxide comprising an alkali metal element A, a tungsten element W, an auxiliary element M, and an oxygen element O, and the alkali metal element A, the tungsten element W, and the auxiliary element M all forming complexes with the oxygen element O. The composite oxide as a cocatalyst can significantly improve the C2 selectivity and C2 yield of the reaction in an OCM bed reactor in which methane and oxygen are fed together, and has a great application value.
