NOVELTY - The method comprises supplying pulverized carbonaceous material (28) and a swirling stream of hydrogen gas (38) to a reactor (34), preheating the reactor to 1200 degrees F, exposing the pulverized carbonaceous material in the reactor to the swirling stream of a hydrogen in the absence of added water to form an exit gas (40) including methane, extracting the exit gas from the reactor, pressurizing the reactor to a reaction pressure of 1000 psi, and delivering the hydrogen gas to a region of the reactor to impart a swirling motion to the hydrogen gas to form the swirling stream.    USE - The method is useful for producing methane from a carbonaceous material such as coal.    ADVANTAGE - The method is capable of efficiently, easily and economically producing compatible methane from a carbonaceous material with high yield and without large quantity of water and any waste contaminants.    DETAILED DESCRIPTION - The method comprises supplying pulverized carbonaceous material (28) and a swirling stream of hydrogen gas (38) to a reactor (34), preheating the reactor to 1200 degrees F, exposing the pulverized carbonaceous material in the reactor to the swirling stream of a hydrogen in the absence of added water to form an exit gas (40) including the methane, extracting the exit gas from the reactor, pressurizing the reactor to a reaction pressure of 1000 psi, delivering the hydrogen gas to a region of the reactor to impart a swirling motion to the hydrogen gas to form the swirling stream, passing the swirling stream of the hydrogen gas from the region to a reaction zone to react the carbonaceous material with the hydrogen gas, exposing the exit gas to a methanation process, capturing ash (48) and transporting the ash from the reactor, and utilizing heat generated from the reactor for a secondary thermal process. The pulverized carbonaceous material is supplied by forming particulates of the carbonaceous material with 70% of the particulates sized to pass through a 100 mesh screen, supplying a carrier fluid and carrying the carbonaceous material in the carrier fluid, conveying the carbonaceous material under a feed pressure to an input of the reactor, and delivering a spray of the material to the reactor. The hydrogen gas is produced from a renewable source and a gasification process. The feed pressure is greater than a reactor pressure. An INDEPENDENT CLAIM is included for a system for producing methane from a carbonaceous material.    DESCRIPTION OF DRAWING(S) - The diagram shows a block diagram of a hydro-gasification system.
