For use in a hydrocarbon feed stream comprising water vapor, CO 2 , CH 4 and CO in an amount such that the H 2 O / CH 4 ratio is less than 0.8 and the CO 2 / CH 4 ratio is greater than 0.5, An aluminum compound-supported nickel reforming catalyst to which a calcium promoter has been added, wherein the feed stream further comprises a large amount of sulfur compounds up to about 20 ppm. The catalyst comprises 0.5 to 25 wt% calcium compound additive, 2 to 30 wt% nickel, and 25 to 98 wt% aluminum compound support, wherein substantially all of the calcium is combined with alumina. Yes. This catalyst can be used in reforming reactions to produce synthesis gas and is advantageous for producing synthesis gas with a low hydrogen: carbon monoxide ratio for applications such as iron ore reduction. |
