10442996 · 2019-10-15 · ·

Ultra-clean char and ultra-clean gaseous hydrocarbons are produced from a carbon-based feedstock to generate maximum efficiency uniform heat and/or electricity in a clean environmentally friendly process. The ultra-clean char and ultra-clean gaseous hydrocarbon streams are produced by pyrolizing organic matter, such as coal or pet coke or any other carbon-based material including land, sea, plastics and industrial waste. The pyrolized organic matter may be combusted in the presence of oxygen to produce heat, which can be used to generate electricity in a conventional boiler/generator system. Further, pyrolized organic matter can be combusted in the presence of carbon dioxide and further processed to produce various hydrocarbons. In other embodiments, the ultra-clean post-combustion ash may be subjected to an extraction process for capturing valuable rare earth elements.

Pyrolysis reactor system and method

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.

Method of producing product gas from multiple carbonaceous feedstock streams mixed with a reduced-pressure mixing gas

A feedstock delivery system transfers a carbonaceous material, such as municipal solid waste, into a product gas generation system. The feedstock delivery system includes a splitter for splitting bulk carbonaceous material into a plurality of carbonaceous material streams. Each stream is processed using a weighing system for gauging the quantity of carbonaceous material, a densification system for forming plugs of carbonaceous material, a de-densification system for breaking up the plugs of carbonaceous material, and a gas and carbonaceous material mixing system for forming a carbonaceous material and gas mixture. A pressure of the mixing gas is reduced prior to mixing with the carbonaceous material, and the carbonaceous material to gas weight ratio is monitored. A transport assembly conveys the carbonaceous material and gas mixture to a first reactor where at least the carbonaceous material within the mixture is subject to thermochemical reactions to form the product gas.

Biomass upgrading system

Aspects provide for volatilizing a biomass-based fuel stream, removing undesirable components from the resulting volatiles stream, and combusting the resulting stream (e.g., in a kiln). Removal of particles, ash, and/or H2O from the volatiles stream improves its economic value and enhances the substitution of legacy (e.g., fossil) fuels with biomass-based fuels. Aspects may be particularly advantageous for upgrading otherwise low-quality biomass to a fuel specification sufficient for industrial implementation. A volatilization reactor may include a fluidized bed reactor, which may comprise multiple stages and/or a splashgenerator. A splashgenerator may impart directed momentum to a portion of the bed to increase bed transport via directed flow.

Process for catalytic gasification of carbonaceous feedstock

An improved process for the catalytic gasification of a carbonaceous feedstock in a dual fluidized bed reactor for producing synthesis gas is disclosed. The disclosure uses ?-alumina as a catalyst support i and heat carrier in the gasification zone (102). The gasification zone (102) is operated at 700-750? C. to prevent substantial conversion of ?-alumina to ?-alumina, which would manifest in the enablement of high catalyst loading and high recyclability. The catalyst is an alkali metal, preferably K.sub.2CO.sub.3, so that conversion proportional to total K.sub.2CO.sub.3 to solid carbon ratio is achieved with as high K.sub.2CO.sub.3 loading as 50 wt % on the solid support. The combustion zone (140) is operated at 800?-840? C., to prevent any conversion of the ?-alumina to ?-alumina, so that catalyst recyclability of up to 98% is achieved between two successive cycles.
