Preparing synthesis gas using hydrotalcite- derived nickel catalysts |
摘要 |
There is provided is a process for preparation of synthesis gas, i.e. mixtures containing dihydrogen and oxides of carbon, from feedstocks containing methane and/or higher hydrocarbons having from about 2 to about 12 carbon atoms by an initial catalytic treatment of feedstock to provide a methane-containing gaseous mixture substantially free of compounds having 2 or more carbon atoms, and reforming the gaseous mixture at elevated temperatures using nickel-containing catalytic materials that are unusually active under mild conditions of conversion and resistant to deactivation. The process consists fundamentally in converting the higher hydrocarbon compounds to form a methane-containing gaseous mixture substantially free of compounds having 2 or more carbon atoms in an initial conversion zone containing a catalyst while controlling temperatures within the initial conversion zone to temperatures in a range of temperature downward from about 500° C. to about 300° C., and reforming the methane-containing gaseous mixture with steam and/or carbon dioxide in a subsequent zone containing catalyst at elevated temperatures and pressure sufficient to form synthesis gas.
