Abstract: A reformer module (10) comprises a hollow support member (12) having at least one passage (14) extending longitudinally therethrough. The hollow support member (14) has an external surface (20), a barrier layer (22) arranged on at least a portion of the external surface (20) of the hollow support member (12), a catalyst layer (24) arranged on the barrier layer (22) and a sealing layer (26) arranged on the catalyst layer (24) and the external surface (20) of the hollow support member (12) other than the at least a portion of the external surface of the hollow support member (12). By providing the barrier layer (22) and the catalyst layer (24) on the exterior surface (20) of the hollow support member (12), the distribution of the barrier layer (22) and/or the catalyst layer (24) may be more precisely controlled and thus a non-uniform distribution of barrier layer (22) and/or catalyst layer (24) may be achieved.

Abstract: An apparatus which is capable of supporting a process for gasifying a variety of hydrocarbon-containing materials. The resulting hydrogen-containing gas is suitable for use in various combustion processes and for petrochemical processes. A hydrocarbon-containing material is mixed with natural gas (or other suitable hydrocarbon gas) under pressure. The suspended material and gas are then injected under pressure into an acceleration/gasification tube. Intense heat (provided by an external energy source) is applied to the mixture as it travels through this tube, resulting in the cracking of the hydrocarbon chains and the release of additional energy. The released bond energy, along with the addition of the external energy, rapidly expands the gas and causes the velocity of the moving mixture to rise sharply as it proceeds down the tube. The acceleration/gasification tube is connected to a diffuser, which is essentially an expansion nozzle with a series of heat exchangers to cool the rapidly expanding gas.
Abstract: A tilted, fixed kiln with rotory steam gasifier having a fixed elongated, pressurizable kiln body member with an input end and an output end and with the center axis supported at an angle to the horizontal so as to bring into effect gravitational forces acting on high moisture content biomass material fed into the input end and travelling through the kiln to the output end and having in the kiln body an axially extending rotor and a motor, radially spaced-apart scoop-like blade elements extending along the axial length of the kiln for tumbling the material, means for increasing the temperature from its input to its output end, spaced-apart blades and chains disposed in the rotor kiln cavities for stirring the biomass material as it travels through the kiln to prevent agglomeration, a plurality of parallel, axially extending hot gas counter-flow feedback pipes arranged around the kiln body and along the backsides of the scoop-like blade elements, a metering auger mounted vertically to the input end of the kiln
