Method of absorbing gases or components of gas mixtures includes introducing from below the gas and a liquid solvent for absorbing the gas into at least one absorbing column having a plurality of vertically spaced filter plates formed of highly porous sintered material and provided with flow-through openings whereby absorption of the gas by the liquid solvent occurs partly within the pores of the filter plates, and passing the liquid solvent with the gas dissolved therein through at least one desorbing column having vertically spaced filter plates similar to those in the absorbing column for desorbing the gas from the liquid solvent.

Improved apparatus for mixing an oxygen containing gas with a vaporized, gasified or atomized hydrocarbon within the mixing chamber of a gas reforming device in which one or more tubes having discharge openings distributed over the flow cross section of the mixing zone supply the oxygen containing gas and further have attached thereto guide baffles which gradually enlarge the unobstructed flow cross section constricted by the tube or tubes.

Method and apparatus for the operation of a gas reformer in conjunction with an internal-combustion engine for the purpose of reducing the pollution of the exhaust gases in which a mixture of fuel and primary air and/or exhaust gas is converted into sootfree reformed gas in the gas reformer in the presence of a catalyst; the reformed gas and secondary air are then supplied to the internal-combustion engine may be recirculated through the gas reformer. From start-up to warm-up to operation under load, fuel is mixed with a decreasing percentage of slightly understochiometric supply of primary air. For operation under load, the primary air is largely replaced by exhaust gas which heats up the mixture fed to the catalyst in the gas reformer. During operation under load, reformed gas is generated as needed by the internal-combustion engine by supplying fuel, exhaust gas and primary air in accordance with the temperature of the catalyst.

Disclosed herein is an improvement for a gas turbine which has been adapted to burn fuel processed by catalytic or non catalytic type gas converters. This adaptation has resulted in the reduction of the harmful polutants being emitted to the environment. The improvement, recognizing that a turbine operating with such processed fuel runs at considerably high combustion chamber temperatures, calls for the positioning of heat exchange mechanisms in the path of the exhaust gases emanating from the turbine''s decompression unit. These mechanisms preheat the fuel and air needed in the conversion process. Additionally, heat exchange mechanisms are positioned about and between the reaction chambers in the gas converter. Part of the exhaust gases are routed through these facilitating the gas conversion process. Further, mixing means are provided wherein the preheated air cooperates with the exhaust gases to reduce the heat of the latter before they pass via the turbine''s decompression unit into the environment. An alternate improvement calls for the placement of a water vaporizer in the path of the exhaust gases. Water supplied thereto is vaporized and then supplied to the gas converter for reaction with the fuel in a known way.

The invention concerns an arrangement for the complete combustion of a liquid fuel. According to the invention, this arrangement comprises a catalytic gas converter (reformed-gas generator) suitable also for heavy hydrocarbons, a radiation plate system and a mixing arrangement for mixing the fuel gas generated by the converter with secondary air and for directing said mixture through said radiation plate for conversion to thermal energy.
摘要:
An improved gas reformer for generating a gas mixture through the catalytic conversion of a vaporized, gasified or atomized liquid fuel which has been mixed with an oxygen containing gas, in which a plurality of successive reaction stages are provided so that fuel not converted in a first reaction stage is converted in a further, succeeding reaction stage. The oxygen containing gas is mixed with the output of each reaction stage which is to be converted in a further reaction stage and the amount of oxygen in the oxygen containing gas in the mixture provided to each reaction stage is controlled in that reaction stage such that the amount of oxygen in the gas mixture is increased with decreasing temperature.
摘要:
This invention relates to a catalytically active substance for the conversion of higher hydrocarbons into gas mixtures, such as those containing carbon monoxide, methane and/or hydrogen, for use in combustion engines, such as the internal combustion engine of an automobile. The catalytically active substance uses a catalyst comprised of oxides of the metals lanthanum, cobalt, nickel and uranium; and an oxidic catalyst carrier for this catalyst. The carrier comprises a metal oxide selected from the group consisting of aluminum oxide, magnesium oxide, silicon oxide, zirconium oxide and titanium oxide. Preferably, the carrier is in the form of one or more porous sintered blocks on which the catalyst has been impregnated.
