    摘要： A method is provided for carbon-dioxide-neutral compensation for current level fluctuations in an electrical power supply system as a result of peaks and troughs in the generation of electrical energy. When a generation peak occurs, electrical energy produced from a regenerative energy source is used in an electrolysis unit for hydrogen generation. A hydrogen flow generated in the electrolysis unit is supplied to a reactor unit that catalytically generates an energy-carrier flow containing hydrocarbon. In a generation trough, the produced energy-carrier flow is burned in a combustion chamber. The thermal energy of the flue-gas flow formed by the combustion is used to generate electrical energy in a turbine process. The generated electrical energy is fed into the electrical power supply system. The flue-gas flow is supplied to the reactor unit as a carbon source for generation of the energy-carrier flow.

    摘要： A process is disclosed for allothermic gasification of coal under pressure with water vapor in a gas generator containing heat-exchange tubes for a heat transfer medium. The hot heat transfer medium that enters the gas generator by the heat-exchange tubes is first introduced in the gasification zone, then in the pyrolysis zone. The coal to be gasified flows counter-currently through the gas generator, so that the current of cooled heat transfer medium is used for heating and pyrolyzing the coal, whereas the heat for gasification is taken from the current of the still hot heat transfer medium. Gas generators vertically or horizontally arranged with fitting designs are used for implementation of the process.

    摘要： A process for producing a synthesis gas containing methane and using a reactor having a fuel containing carbon comprises directing gasification gases in a circulation system through a bed of fuel containing carbon to form a synthesis gas containing methane and carbon dioxide. Thereafter, the synthesis gas is cooled in a regenerator and subjected to the gas separation wherein the syngas is subjected to a gas cleansing by means of a pressure change absorption in a gas scrubber to remove most of the methane and carbon dioxide and its water content is increased. The separated gas is then heated and subsequently the portion is returned into the system together with the waste gases and fuel containing carbon. The process includes a 4-pole heater which includes the first heat exchange passage for the syngas which is cooled and a second heat exchange passage for the recirculation of the syngas and is further cooled and passed through a scrubber. The system includes a heater which is arranged after the 4-pole heater which operates the gas and then the gas is passed through a reduction reactor back through a heating element of the regenerator that initially cooled the gas. A portion of the gas is also used to drive a steam turbine and to direct the excess steam from the turbine into the initial reactor which has a fluidized bed of the carbon material such as coal.

    摘要： The present invention concerns a method of and a device for directly reducing fine-particle ore in a horizontal reactor with an ore-reducing gas and a heat vehicle, also a gas, in a fluidized bed.The ore-reducing vessel itself comprises a horizontal fluidized-bed reactor (1). The ore (F) is blown into it from below. The heated ore-reducing gas (A) is blown into the reactor through oncoming-gas floors (2). The heat needed for the endothermic reaction is supplied to the reactor at different temperatures through heat exchangers (3) and transferred to the bed. Heat is supplied counter to the ore-reducing gas.Fuel (B) in the form of gas is burned with air (C) to make the heat vehicle (D). The ore-reducing gas (A') is heated in downstream heat exchangers (5.1 to 5.3) before arriving in the three sections (1a, 1b, & 1c) of the reactor through the floors.Sponge iron (6) is removed and throat gas (E) extracted from a sponge-collecting section (1d).

    摘要： A method and device are provided for direct reduction of ore fines in a wide range of particle size, the reducing agent being hydrogen placed in a fluidized bed gutter with a plurality of sequentially arranged chambers. The fluidization rate in the supply base is set so that a defined class of particle size remains in the chamber concerned where it will be submitted to a reduction process and that the finest particle size fraction is discharged from the chamber, then precipitated in a hot gas cyclone to solid material (or fines) and gas. The ore fines precipitated in the cyclone then reaches the following chamber. The gas from all the hot gas cyclones is fed by a collector to the pre-heater. After reduction in the chambers, the ore fines are conveyed in pressure vessels for submission to further processes.
