Hydromethanation of a carbonaceous feedstock

The present invention relates to processes for hydromethanating a carbonaceous feedstock to a methane-enriched synthesis gas, where an oxygen-rich gas stream and the carbonaceous feedstock are fed into a fluidized-bed hydromethanation reactor, and where the carbonaceous feedstock as fed into the hyd...

More Information
Summary:The present invention relates to processes for hydromethanating a carbonaceous feedstock to a methane-enriched synthesis gas, where an oxygen-rich gas stream and the carbonaceous feedstock are fed into a fluidized-bed hydromethanation reactor, and where the carbonaceous feedstock as fed into the hydromethanation reactor has an elevated moisture content in order, for example, to assist in heat management within the hydromethanation reactor.
