    摘要: A process for the multi-stage catalytic methanization of a carbon monoxide-containing and hydrogen-containing feed gas at high pressure and temperature is carried out in three stages. In the first stage the feed gas is premethanized at a temperature of from 400.degree. to 500.degree. C.; in a second stage the premethanized gas is converted and in a third stage the converted gas is finally methanized at a temperature of from 300.degree. to 380.degree. C. Apparatus for carrying out this process preferably comprises a single elongated pressure reactor which is divided into three reaction zones each of which contains a reaction catalyst formed into a fluidized bed. The feed gas preferably flows upwards through the reactor firstly through the first fluidized bed, then through the second fluidized bed and finally through the third fluidized bed after which the product gas is withdrawn from the top of the reactor. The reactions takes place isothermally and for this purpose each of the zones is preferably provided with an independent cooling system.

    摘要: An outer enclosed pressure container is formed of a simple steel material. An inner enclosed container is positioned within the pressure container such that there is an intermediate space therebetween. Catalyst layers are provided within the inner container. A gas containing a reducing component and water vapor are introduced into the inner container and are therein reacted by means of the catalyst to perform a desired reducing reaction. At least part of the water vapor is alone introduced into the intermediate space to thereby pressurize the intermediate space to substantially the same pressure as occurs within the inner container. The water vapor in the intermediate space operates to protect the wall of the pressure container from the temperatures occurring due to the catalytic reaction within the inner container. The water vapor is removed from the intermediate space and is at least partially added to the gas containing a reducing component before the introduction thereof into the inner container.

    摘要: In methanizing CO and H.sub.2 containing charge gases, the charge gas is passed upwardly through a vertically extending fluidized bed reactor flowing, in turn, through a fluidized bed zone, a dust bed zone and a separation zone. From the separation zone, the gas is conveyed out of the reactor to a point of use. Coolant tubes are positioned in the reactor passing vertically through the fluidized bed zone, the dust bed zone and the separation zone for removing the heat generated in the reaction. An evaporable coolant, preferably water, is circulated through the coolant tubes. In a separate steam drum, the vapor pressure of the coolant is set for maintaining constant the temperature of the vaporizing coolant.

    摘要: Small, pourable particles of comminuted coal for coking purposes are gravity-discharged into a stream of hot gas flowing upwardly in a flight stream tube, in a direction inclined and generally opposite to the gas flow direction. Just prior to entry into the gas stream the particles are fluidized so that, on being entrained by the gas stream, they will become uniformly distributed throughout the cross-section of the same. A method and an apparatus are disclosed.

    摘要: A method of catalytic conversion of feed gases, particularly of a low-sulphur gas mixture rich in carbon monoxide and hydrogen, into a product gas mixture containing methane and/or higher hydrocarbons under high pressure includes the step of removing heat of reaction from the catalytic conversion from a reaction zone by feeding both water and steam to form a cooling medium through a pipe coil in the reaction zone. This forms superheated steam in the pipe coil and the superheated steam is then converted into another form of energy, for example in a turbo-generator. Preferably the reaction zone is a fluidized bed. The apparatus for carrying out this method comprises a reactor, which is preferably a fluidized bed reactor and in this reactor the piping system forming the superheater is disposed in the lower part of the reaction zone. The superheater is connected to a feedwater line and to a steam inlet line and a steam turbine is connected to a steam output line leading from the superheater.
