摘要： A system for converting fuel may include a first moving bed reactor, a second reactor, and a non-mechanical valve. The first moving bed reactor may include at least one tapered section and multiple injection gas ports. The multiple injection gas ports may be configured to deliver a fuel to the first moving bed reactor. The first moving bed reactor may be configured to reduce an oxygen carrying material with a fuel by defining a countercurrent flowpath for the fuel relative to the oxygen carrying material. The second reactor may communicate with the first moving bed reactor and may be operable to receive an oxygen source. The second reactor may be configured to regenerate the reduced oxygen carrying material by oxidation.

摘要： A dual bed pyrolysis system may include a falling bed reactor employing a heat carrier particulate to pyrolyze biomass to create a pyrolysis product and a pyrolysis waste product. The dual bed pyrolysis system may also include a fluidized bed reactor. The fluidized bed reactor may accept the pyrolysis waste product including char and heat carrier particulate from the falling bed reactor. The fluidized bed reactor may combust the char in the presence of the heat carrier particulate. The fluidized bed reactor may combust the char to reheat the heat carrier particulate. The reheated heat carrier particulate may be provided to the falling bed reactor to pyrolyze biomass to create a pyrolysis product and a pyrolysis waste product.

摘要： A heat receiver, a reactor, and a heater utilize the heat of concentrated solar light for thermal decomposition and/or chemical reaction of coals, etc. The heat receiver includes: a side portion forming a substantially cylindrical side surface; a substantially circular bottom portion connected to the lower edge of the side portion; and a ceiling connected to the upper edge of the side portion. A substantially circular aperture is formed in the center of the ceiling. The heat receiver has a substantially cylindrical cavity and the opening portion is open. When the cavity has a diameter of D and a length of L, and the aperture has a diameter of d, d=D/2 or less and L=2D or more. Concentrated solar light entering the heat receiver is to be contained in the heat receiver to effectively utilize the solar light.

摘要： The present invention is directed to a process for polymerizing olefins in gas phase in a fluidized bed reactor having a vertical body, a generally conical downwards tapering bottom zone, a generally cylindrical middle zone above the bottom zone, and a generally conical upwards tapering top zone above the middle zone. The fluidization gas is withdrawn from the top zone of the reactor, compressed and cooled so that a part of the fluidization gas condenses and then introduced to the bottom zone of the reactor. The bed is thus cooled upon evaporation of the liquid. There is no fluidization grid in the reactor.
