摘要： A system for the pyrolysis of a pyrolysis feedstock utilizes a pyrolysis reactor for producing pyrolysis products from the pyrolysis feedstock to be pyrolyzed. An eductor condenser unit in fluid communication with the pyrolysis reactor is used to condense pyrolysis gases. The eductor condenser unit has an eductor assembly having an eductor body that defines a first flow path with a venturi restriction disposed therein for receiving a pressurized coolant fluid and a second flow path for receiving pyrolysis gases from the pyrolysis reactor. The second flow path intersects the first flow path so that the received pyrolysis gases are combined with the coolant fluid. The eductor body has a discharge to allow the combined coolant fluid and pyrolysis gases to be discharged together from the eductor. A mixing chamber in fluid communication with the discharge of the eductor to facilitates mixing of the combined coolant fluid and pyrolysis gases, wherein at least a portion of the pyrolysis gases are condensed within the mixing chamber.

摘要： gasifier and a gasification process provides a long, uniform temperature zone in the gasifier, regardless of the particle size, chemical composition, and moisture content of the fuel by sandwiching a reduction zones between two oxidation zones. The gasifier and gasification process produces a char that is more energy-dense and almost devoid of moisture, affording an additional (char) oxidation zone with a temperature that is higher than a first oxidation zone which is closer to an evaporation and devolatilization zone. As such, the additional (char) oxidation zone contributes to augmenting the reduction zone temperature, providing a favorable dual impact in improving syngas composition and near-complete conversion of the tar.

摘要： Disclosed is a pyrolysis system (1) comprising a pyrolysis reactor (2) arranged for producing pyrolysis gas and a first condensing unit (3) arranged to cool the pyrolysis gas to a first temperature to condense a first pyrolysis liquid (20). The system further comprises a second condensing unit (4) arranged to cool the pyrolysis gas to a second temperature to condense a second pyrolysis liquid (21), wherein the first temperature is higher than the second temperature. The system also comprises a return conduit (5) arranged to guide a portion of the pyrolysis gas back into the pyrolysis reactor (2) to drive the pyrolysis process, and heating means (6) arranged to increase the temperature of the portion of the pyrolysis gas before it reenters the pyrolysis reactor (2). The pyrolysis reactor (2) is a fixed bed counterflow pyrolysis reactor (2) comprising a pyrolysis gas outlet (7) arranged at an upper part (8) of the pyrolysis reactor (2) through which the produced pyrolysis gas leaves the pyrolysis reactor (2), a pyrolysis gas inlet (9) arranged at a lower part (10) of the pyrolysis reactor (2), through which the heated pyrolysis gas reenters the pyrolysis reactor (2), a feedstock inlet (11) arranged at the upper part (8) of the pyrolysis reactor (2) through which feedstock (19) enters the pyrolysis reactor (2) and a char outlet (12) arranged at the lower part (10) of the pyrolysis reactor (2), through which char produced in the pyrolysis reactor (2) leaves the pyrolysis reactor (2). Furthermore, a method for producing producing purified pyrolysis gas and pyrolysis liquids and use of a pyrolysis system (1) is disclosed.

摘要： A method for gasifying carbon-containing materials in which the material for gasification and oxygen, usually in the form of air, are supplied to a gas generator where the gasification takes place in a fixed bed reactor. The product gas is drawn off via a product gas line and introduced into a hot gas filter. A filter, preferably provided with filter candles, removes solids such as particles not yet gasified, ash and foreign bodies, while clean gas passes through and is taken off via a clean gas line. An outlet is provided in the bottom region of the hot gas filter to remove residual solids. The hot gas filter is supplied through a line with oxygen, preferably in the form of air, in its middle height region, between the filter bottom and the outlet.

摘要： A universal feeder system that combines with a fluidized bed gasification reactor for the treatment of multiple diverse feedstocks including sewage sludge, municipal solid waste, wood waste, refuse derived fuels, automotive shredder residue and non-recyclable plastics. The invention thereby also illustrates a method of gasification for multiple and diverse feedstocks using a universal feeder system. The feeder system comprises one or more feed vessels and at least one live bottom dual screw feeder. The feed vessel is rectangular shaped having three vertical sides and an angled side of no less than 60 degrees from the horizontal to facilitate proper flow of feedstock material that have different and/or variable flow properties. The feedstocks are transferred through an open bottom chute to a live bottom dual screw feeder and through another open bottom chute to a transfer screw feeder that conveys feedstock to the fuel feed inlets of a gasifier.

摘要： This invention relates to a power recovery process in waste steam/CO2 reformers in which a waste stream can be made to release energy without having to burn the waste or the syngas. This invention in some embodiments does not make use of fuel cells as a component but makes use of exothermic chemical reactors using syngas to produce heat, such as Fischer-Tropsch synthesis. It also relates to control or elimination of the emissions of greenhouse gases in the power recovery process of this invention with the goal of producing energy in the future carbonless world economy.
