Abstract: A catalytic reactor including: a reaction container filled with a catalyst having ruthenium; and an introduction part for introducing a material fluid to the reaction container. The reaction container is supplied with a mixed gas as material fluid to produce synthetic gas containing hydrogen and carbon monoxide in the presence of the catalyst. The introduction part is connected to the reaction container in a horizontal direction or a direction inclined downward from above a horizontal plane, and a height of the catalyst filled in the reaction container is adjusted above a height at which the material fluid is fed from the introduction part to the reaction container. Also, a method of using the catalytic reactor including monitoring a molar ratio of carbon and oxygen contained in the material fluid and stopping the supply of an oxygen-containing gas to the reaction container before the molar ratio becomes excessively low.

Abstract: The present invention provides a system and method for evaluating effects of process parameters on hydrogasification processes. The system includes a hydrogasification reactor, a pressurized feed system, a hopper system, a hydrogen gas source, and a carrier gas source. Pressurized carbonaceous material, such as coal, is fed to the reactor using the carrier gas and reacted with hydrogen to produce natural gas.

Abstract: There is provided a technique for manufacturing a hydrogen-containing gas. An oxygen-containing gas is mixed with a feed gas obtained by mixing steam with a hydrocarbon fuel, this mixture is introduced into a catalytic reaction chamber, and a partial oxidation reaction and a steam reforming reaction are conducted to obtain a hydrogen-containing gas. In this reforming, an antechamber of the catalytic reaction chamber is heated up to a self-ignition temperature in a first catalyst section, where the self-ignition temperature is the temperature at which a mixed gas self-ignites during the advection period required for the mixed gas to move from a mixing chamber to the catalytic reaction chamber, with this temperature being at least a minimum partial-oxidation temperature and lower than a minimum steam reforming temperature.
