1. A process for converting carbonaceous material to energetic gases, the process comprising
a) forming a liquid suspension slurry of particles of carbonaceous material in water; and
b) feeding hydrogen and the suspension slurry into a hydro-gasification reactor without a reaction catalyst at a temperature and pressure sufficient to generate methane and carbon monoxide rich producer gases, wherein the ratio of water to dry carbonaceous material in the hydrogasification reactor is at least 2:1.
