摘要： The device for pyrolysis of carbonaceous materials comprises a working chamber comprising a non-magnetic wall comprising an inner graphite lining; one or more electrodes adapted to be inserted within a carbon-based bedding; a solenoid coiled around the device exterior, the solenoid adapted to create a magnetic field within the working chamber such that when the solenoid is energized, the carbon-based bedding is caused to move; a lower solids outlet comprising an airlock, the solids outlet adapted to permit solids to exit the device; and a lower gas outlet adapted to permit gaseous substances to exit after having traveled through the carbon-based bedding. The method comprises the steps of loading carbon-containing materials into the working chamber; using the first and second electrodes to heat the carbon-containing materials by passing electric current through the carbon-containing materials without air access; collecting, cleaning and releasing gaseous pyrolysis products produced by the heating.

摘要： The invention relates to a method for producing syngas in combined operation with a metallurgical plant which comprises at least one blast furnace for producing crude iron, a converter steel mill and a coke-oven plant. Part of the blast-furnace top gas that is produced in the production of crude iron and/or part of the converter gas that occurs in the converter steel mill and/or part of the coke-oven gas that is produced in the coke-oven plant are mixed. By choosing the gas streams that are brought together to form a mixed gas and/or by changing the mixing ratios of the gas streams that are brought together, at least two streams of useful gas are produced, differing with regard to their composition and respectively prepared to form streams of syngas.

摘要： A shear retort mill for slow ablative pyrolysis features friction heating between shearing surfaces on a rotating disk and a static or rotating cylindrical drum enclosing the disk. A feed enters the workspace between the rotating disk and the bottom of the drum through a hollow feed shaft coupled to the rotating disk. Preferably, an auger compacts and moves the feed downward, and a shredder reduces the feed's particle size. The feed is increasingly ground and pyrolyzed as it is forced between the drum and disk shearing surface. As the dense processed material extrudes at the edge of the workspace, the gases and liquid products are forced inward by the barrier of dense solids. A static exhaust pipe at the center of the rotating feed shaft allows for the exit of these gases, which preferably go to a heat exchanger to recover any condensable fractions.

摘要： The present invent provides improved rapid thermal conversion processes for efficiently converting wood, other biomass materials, and other carbonaceous feedstock (including hydrocarbons) into high yields of valuable liquid product, e.g., bio-oil, on a large scale production. In an embodiment, biomass material, e.g., wood, is feed to a conversion system where the biomass material is mixed with an upward stream of hot heat carriers, e.g., sand, that thermally convert the biomass into a hot vapor stream. The hot vapor stream is rapidly quenched with quench media in one or more condensing chambers located downstream of the conversion system. The rapid quenching condenses the vapor stream into liquid product, which is collected from the condensing chambers as a valuable liquid product. In one embodiment, the liquid product itself is used as the quench media.

摘要： The present technology is generally directed to systems and methods of controlling or reducing the output rate of a coke oven through gas sharing providing an extended process cycle. In some embodiments, a method of gas sharing between coke ovens to decrease a coke production rate includes operating a plurality of coke ovens to produce coke and heated exhaust gases. In some embodiments, a first coke oven is offset in operation cycle from a second coke oven. The method further includes directing the heated exhaust gases from the first coke oven to the second coke oven while the second coke oven is mid-cycle. The heat transfer allows the second coke oven to extend its cycle while staying above a critical operating temperature. By extending the operational cycle while generally maintaining output per cycle, overall production is decreased.

摘要： A method is disclosed for treating the effluent from a hydrocarbon pyrolysis unit without employing a primary fractionator. The method comprises passing the gaseous effluent to at least one primary heat exchanger, thereby cooling the gaseous effluent and generating high pressure steam, and then cooling the gaseous effluent to a temperature at which tar, formed by reactions among constituents of the effluent, condenses. The gaseous effluent and the condensed tar are fed to at least one knock-out drum, whereby the tar is separated from the gaseous effluent. The gaseous effluent is then further cooled to condense a pyrolysis gasoline fraction from the effluent and to reduce the temperature of the effluent to a point at which it can be compressed efficiently. The condensed pyrolysis gasoline fraction is separated from the effluent and then distilled so as to reduce its final boiling point.

摘要： A low-temperature carbonization/combustion process is carried out in a low-temperature carbonization/combustion plant with pressure control that includes a pyrolysis drum to which waste is delivered. Low-temperature carbonization gas generated there is passed to a combustion chamber. Flue gas produced there is fed through a cooling device and a gas compressor to a stack. With the aid of a control device, the speed of rotation of the gas compressor is controlled in relation to the pressure in the gas path between the pyrolysis drum and the gas compressor in such a way that when the pressure decreases, the speed of rotation is decreased. Preferably, an additional gas compressor is connected in series with the gas compressor and the speed of rotation of the additional gas compressor is appropriately controlled. An additional pyrolysis drum can also be provided.
