Catalytic reforming process
Methane and other hydrocarbons boiling up to about 450/sup 0/F are converted into hydrogen and carbon oxides by reacting the hydrocarbon feed material with steam in the presence of a carbon-alkali metal catalyst at a temperature in the range between about 1200/sup 0/ and about 1700/sup 0/F and at a pressure between about atmospheric and about 5000 psig. The catalyst employed may be prepared by reacting coal, coal char, coke or other carbonaceous solids with an alkali metal or alkali metal compound at an elevated temperature. Such a catalyst is highly effective for the steam reforming of methane and similar hydrocarbon feed streams and at the same time is resistant to high temperature sintering and poisoning by sulfur compounds present in the feed.
