Nickel-catalyst for syngas generation by mixed reforming using CO2 and steam

A calcium promoted, aluminum compound supported nickel reforming catalyst for use in a hydrocarbon feed stream containing steam, CO 2 , CH 4 , and CO at levels such that the ratio of the H 2 O/CH 4 is less than 0.8 and the ratio of the CO 2 /CH 4 is greater than 0.5 and the feed stream further conta...

More Information
Summary:A calcium promoted, aluminum compound supported nickel reforming catalyst for use in a hydrocarbon feed stream containing steam, CO 2 , CH 4 , and CO at levels such that the ratio of the H 2 O/CH 4 is less than 0.8 and the ratio of the CO 2 /CH 4 is greater than 0.5 and the feed stream further containing high quantities of sulfur compounds up to about 20 ppm. The catalyst contains from 0.5 percent to 98 percent by weight of a calcium compound additive, from 2 percent to 30 percent by weight nickel, and from 25 percent to 98 percent by weight of an aluminum compound carrier, wherein substantially all of the calcium is combined with the alumina. The catalyst can be used in reforming reactions to produce syngas and has advantages in producing low hydrogen to carbon monoxide ratio syngas for applications such as iron ore reduction.
