Title:
CHROMIUM-BASED CATALYSTS AND PROCESSES FOR CONVERTING HYDROCARBONS TO SYNTHESIS GAS
Document Type and Number:
WIPO Patent Application WO2001060740
Kind Code:
A3
Abstract:
Processes for the catalytic conversion of hydrocarbons to carbon monoxide and hydrogen employing new chromium-based catalysts are disclosed. One highly active and selective catalyst system, providing greater than 95 % CH4 conversion, and 97-98 % selectivity to CO and H2, is a chromium-containing catalyst consisting of a CoCr2O4 cubic spinel precursor dispersed in a chromium oxide matrix. Some other preferred catalysts compositions comprise nickel-chromium containing and rare earth-chromium containing compounds.
