Abstract
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 at a specified zone in order to assist in heat management within the hydromethanation reactor.
