    摘要: A process for the production of synthetic natural gas or town gas is described wherein the hot gaseous product of the partial combustion of a carbonaceous fuel, containing hydrogen and carbon monoxide, is passed into a carburetting zone at a temperature of from 700 to 1100*C and therein enriched with a volatile hydrocarbon carburant which on evaporation into the hot gaseous product of partial combustion is thermally cracked into methane and lighter unsaturated hydrocarbons. The carburetted gas product is then passed into a hydrogenation zone maintained at a temperature sufficient to further decompose any remaining hydrocarbon carburant and to hydrogenate the unsaturated hydrocarbons. In this process coke formation in the carburetting zone is substantially minimized by introducing the volatile hydrocarbon carburant into the carburetting zone in the form of a thin layer of liquid which is maintained at a temperature below that at which thermal cracking occurs during the time the carburant is not adsorbed by the hot gas stream.

    摘要: Steam is provided to the primary inlet (16) of an ejector (13), which also receives natural gas at a secondary inlet (28). A computer responds to a signal (37) indicating current in the load of a fuel cell as well as a signal (43) indicating temperature of a steam reformer (10) to move a linear actuator (23) to control a needle (21) that adjusts the size of the steam orifice. Reformate is fed to a separator scrubber (48) which cools the reformate to its dew point indicated by a sensor (71). From that, a controller (25) generates the fuel/carbon ratio for display (84) and to bias a signal on a line (24) regulating the amount of steam passing through an ejector (13) to the inlet (11) of the reformer. Alternatively, the reformate may be cooled to its dew point by a controllable heat exchanger (58a) in response to pressure (94) and temperature (71) signals.

    摘要: An improved multiple-tube catalytic reformer comprising a tubular body containing a radiator core having a plurality of longitudinal cells for low-pressure flow-through of combustion gases, the core being formed preferably either by winding of corrugated metal or as an extruded metal monolith. A plurality of reformer tubes, preferably non-cylindrical, containing hydrocarbon catalyst are arrayed in longitudinal openings within the radiator core and preferably are brazed thereto to maximize heat transfer from the radiator core to the reformer tubes. During manufacture, the metal radiator core is economically bored by laser cutting to form the openings to admit the reformer tubes for brazing. Preferably, the reformer tubes are numbered, sized, shaped, and arrayed to minimize the longest conduction path in the radiator core to the center of any reformer tube.

    摘要: A method of hydrogenation of unsaturated hydrocarbons for syngas production is presented. A hydrogenation feed reactor stream is introduced into a hydrogenation reactor, thereby producing a reformer feed stream. The reformer feed stream is introduced into a reformer, thereby producing a crude syngas stream. The crude syngas stream is introduced into a water gas shift converter, thereby producing a hydrogen-rich stream. The hydrogen-rich stream is separated in a separation means, thereby producing a carbon dioxide-rich stream and a hydrogen product stream. At least a portion of the hydrogen product stream is combined with a refinery fuel gas stream, and a natural gas stream, to form the hydrogenation reactor feed stream.

    摘要: A method for producing methane (69) from a carbonaceous (22) material includes conveying pulverized carbonaceous material (28) entrained in an inert carrier fluid, such as carbon dioxide (36), into a reactor (34). The reactor (34) includes a vortex region (72) for receiving hydrogen gas (38) and imparting a swirling motion to the hydrogen gas (38). The pulverized carbonaceous material (28) is exposed to the swirling stream of hydrogen gas (38) in a first reaction zone (114) within the reactor (34) to form an exit gas (40) that includes methane (69). Remaining unreacted carbonaceous material (28) is further exposed to the hydrogen gas (38) in a second, low velocity, reaction zone (120). The methane rich exit gas (40) is subsequently extracted from the reactor (34) for further processing.
