摘要： A two-stage syngas production method to produce a final product gas from a carbonaceous material includes producing a first product gas in a first reactor, separating char from the first product gas to produce separated char and char-depleted product gas, and separately reacting the separated char and the char-depleted product gas with an oxygen-containing gas in a second reactor to produce a final product gas. The separated char is introduced into the second reactor above the char-depleted product gas. The solids separation device may include serially connected cyclones, and the separated char may be entrained in a motive fluid in an eductor to produce a char and motive fluid mixture prior to being transferred to the second reactor. A biorefinery method produces a purified product from the final product gas.

摘要： A solids discharge system (SDS) is configured to separate solids from product gas. The system includes a solids separation device and at least one solids transfer conduit configured to receive solids from the solids separation device. The solids transfer conduit is selectively partitioned into a plurality of compartments (or “sections”) along its length by isolation valves. A gas supply conduit and a gas discharge conduits are connected to one of the sections to facilitate removal of solids. A filter in fluid communication with that section is configured to prevent solids from passing through the gas discharge conduit so that the solids can be removed from one of the sections of the solids transfer conduit. A product gas generation system incorporates first and second reactors, the latter of which receives products created by the second reactor.

摘要： The present invention demonstrates a solid fuel grade gasification-combustion dual bed poly-generation system, comprising a combustion system, a gasification system, a synthesized gas cooling and purifying system and a synthesized gas methanization system. The combustion system is connected with the gasification system through a circulating material return system. The gasification system mainly adapts the circulating fluidized-bed combustion mode. The gasification system adapts the fluidized-bed incomplete gasification method and the generated semi-coke is returned to the combustion system for re-utilization. The synthesized gas purifying and cooling unit adapts water cycling and combustible recycling. The by-products, CO2 and steam, in the methanization unit can be recovered, so the maximum utilization rate of energy in this system is realized.

摘要： A system includes a first reactor that may gasify a first feed to generate a first syngas. The first feed has a first particle size distribution (PSD1). The system also includes a second reactor that may receive the first feed, a second feed, and at least a portion of the first syngas. The second reactor may gasify the second feed to generate additional syngas, and the second feed has a second particle size distribution (PSD2) that is different from the first PSD. The second reactor includes an elutriation zone disposed on a first end of the second reactor. The elutriation zone may receive the first and second feed. The second reactor also includes a fluidized bed disposed at a second end of the second reactor that is substantially opposite the first end. The fluidized bed is fluidly coupled to the first reactor and may receive the portion of the first syngas via a syngas inlet. The system also includes a gas-solids separation section fluidly coupled to the first and second reactors. The gas-solids separation section may receive the first feed and partially reacted particles of the second feed from the elutriation zone and may feed a combined feed consisting of the first feed and the partially reacted particles of the second feed to the first reactor.

摘要： Provided herein is a method for devolatizing a solid feedstock. The solid feedstock is treated to a produce a particle size laying between 1 cm3 and 100 cm3. The solid feedstock is passed into a device connected to an outlet of a compaction screw auger comprising an assembly including a solid feedstock injector, a retort, a side arm for injecting a heated gas comprising hydrogen, and a process auger. The solid feedstock is contacted with the heated gas at a temperature of 500° C. to 1000° C. for a time of 60 seconds to 120 seconds, whereby the solid feedstock is converted into a gas stream and a solid stream.

摘要： A solids circulation system receives a gas stream containing char or other reacting solids from a first reactor. The solids circulation system includes a cyclone configured to receive the gas stream from the first reactor, a dipleg from the cyclone to a second reactor, and a riser from the second reactor which merges with the gas stream received by the cyclone. The second reactor has a dense fluid bed and converts the received materials to gaseous products. A conveying fluid transports a portion of the bed media from the second reactor through the riser to mix with the gas stream prior to cyclone entry. The bed media helps manipulate the solids that is received by the cyclone to facilitate flow of solids down the dipleg into the second reactor. The second reactor provides additional residence time, mixing and gas-solid contact for efficient conversion of char or reacting solids.

摘要： Using a method and installation for separating acid components, dust and tar from hot gases of gasification installations, an economical method using a corresponding installation is to be created, which enables acid compounds HF, HCl, H2S, dust and tar to be reliably separated in the highest possible temperature range. The aim is achieved in that the media flow leaving the gasification at above 700° C. is fed with additives to a desulfurization process and subsequently to a combined cyclone 9 having associated filter cartridges 17 in a common vessel 8, and the gas is withdrawn for further use downstream of the filter cartridges.

摘要： Certain aspects of the system and method concern producing hydrocarbons from biomass. The method is particularly useful for producing substitute natural gas from forestry residues. A biomass feedstock may be converted into a product hydrocarbon by fast pyrolysis. The resulting pyrolysis gas is converted to the product hydrocarbon and carbon dioxide in the presence of hydrogen and steam while simultaneously generating the required hydrogen by reaction with steam under prescribed conditions for self-sufficiency of hydrogen. Methane is a preferred hydrocarbon product. A system also is described for cycling the catalyst between steam reforming, methanation and regeneration zones.
