Methods and systems are provided for the conversion of waste plastics into various useful downstream recycle-content products. More particularly, the present system and method involves integrating a pyrolysis facility with a cracker facility by introducing at least a stream of r-pyrolysis gas into the cracker facility. In the cracker facility, the r-pyrolysis gas may be separated to form one or more recycle content products, and can enhance the operation of the facility.

Chemical recycling facilities for processing mixed plastic waste are provided herein. Such facilities have the capability of processing mixed plastic waste streams and utilize a variety of recycling facilities, such as, for example, solvolysis facility, a pyrolysis facility, a cracker facility, a partial oxidation gasification facility, an energy generation/energy production facility, and a solidification facility. Streams from one or more of these individual facilities may be used as feed to one or more of the other facilities, thereby maximizing recovery of valuable chemical components and minimizing unusable waste streams.

A method for processing feedstock is described, characterized in that incoming feedstock is processed to selectively recover biogenic carbon material from the incoming feedstock. In some embodiments the incoming feedstock is comprised of mixed solid waste, such as municipal solid waste (MSW). In other embodiments the incoming feedstock is comprised of woody biomass. In some instances, the incoming feedstock is processed to selectively recover biogenic carbon material from the incoming feedstock to produce a processed feedstock having biogenic carbon content of 50% and greater suitable for conversion into biogenic carbon Fischer Tropsch liquids. The high biogenic carbon Fischer Tropsch liquids may be upgraded to biogenic carbon liquid fuels. Alternatively, the incoming feedstock is processed to selectively recover plastic material from the incoming feedstock to produce a processed feedstock having biogenic carbon content of 50% or less.

A double fluidized bed reactor system including a staircase-type helical blade is proposed. The system includes a bubbling fluidized bed gasification furnace for receiving fuel (for example, combustible waste and biomass) and steam, forming a bubbling fluidized bed through a flow of flow medium therein, and gasifying the fuel, thereby generating a resultant gas, and a high-speed fluidized bed combustion furnace for receiving char of the resultant gas and the flow medium from the bubbling fluidized bed gasification furnace, additionally receiving air, combusting the char so as to heat the flow medium, and transferring the heated flow medium back to the bubbling fluidized bed gasification furnace.

A pulverizer that pulverizes coal into pulverized coal; a gasifier that gasifies pulverized coal pulverized by the pulverizer; a combustor that combusts a gasified gas gasified by the gasifier; a compressor that supplies compressed air to the combustor; a gas turbine driven by a combustion gas generated by the combustor; a generator driven by the gas turbine to generate power; a flue gas supply channel that guides a part of a flue gas from the gas turbine to the pulverizer; an IGV that adjusts a flow rate of air supplied from the compressor to the combustor; and a controller that applies an air flow-rate reduction operation to control the IGV so that the flow rate of air is smaller than a set air flow rate determined from a set combustion temperature of the combustor.

A process and system for liquefying and plasticizing a waste plastic in a pyrolysis film reactor are provided. More particularly, a liquefied waste plastic, which may include halogen-depleted molten waste plastics, may be pyrolyzed in a pyrolysis film reactor to form a pyrolysis oil and a pyrolysis gas. The pyrolysis film reactors may include a falling film reactor and/or an upflow film reactor.

A hydrogen composition having a recycle content value is obtained by processing a recycle content feedstock to make a recycle content hydrogen or by deducting from a recycle inventory a recycle content value applied to a hydrogen composition. At least a portion of the recycle content value in the feedstock or in an allotment obtained by a hydrogen manufacturer has its origin in recycled waste plastics.

The invention relates to the field of gasification of a carbonaceous feedstock and can be used in the chemical, petrochemical, coke-gas and energy industries. A method for gasification of a carbonaceous feedstock comprises partial oxidation of the carbonaceous feedstock in an oxidation chamber in a mixture of oxygen-containing gas and water vapour in a partial oxidation channel, which is mounted coaxially in the vertical oxidation chamber. The water vapour for the partial oxidation of the carbonaceous feedstock is supplied at the input and output of the vertical oxidation chamber of a combustion chamber. A gas producer comprises a housing, a burner device, a vertical oxidation chamber, manifolds for supplying carbonaceous feedstock, water vapour and oxygen-containing gas, a pipe for discharging gasification products, a slag removal chamber, and also a partial oxidation channel, which is arranged coaxially in the vertical oxidation chamber and is attached to an upper internal part of the housing, in which the burner device is installed. What is achieved is the production of producer gas with an elevated concentration of hydrogen.

A system for gasifying a carbonaceous feedstock, such as municipal waste, to generate power includes a devolatilization reactor that creates char from the feedstock and a gasifier that creates a product gas from both the char and from volatiles released when devolatilizing the feedstock. The product gas is reacted in a fuel cell to create electrical energy and process heat. The process heat is used to heat the devolatilization reactor and the gasifier. The gasifier comprises a plurality of configurable circuits that can each be tuned to meet the individual needs of the char material being gasified.

The present invention relates to a method for gasification of carbon-containing materials including biohazard wastes, and more specifically, to a method for gasification of carbon-containing materials which allows an increase in carbon efficiency and a reduction in carbon dioxide emission, comprising the steps of: biohazard wastes grinding and sterilization, mix with carbon-containing materials for the gasification; and catalytic production of diesel fuel. A system having a movable platform including: material preparation block, gasification and catalytic of diesel fuel production reactors which are structurally and functionally integrated. In the practice of the process, a mixture of carbon-containing materials, a compressed air feed and process steam is fed to the gasifier to produce a synthesis gas. The synthesis gas is fed to the Fischer-Tropsch reactor where it is catalytically reacted to produce heavy hydrocarbons. The outlet from the Fischer-Tropsch reactor is separated into water, a low heating value tail gas, and the desired hydrocarbon liquid product. The water is pressurized and heated to generate process steam. The system further includes a plurality of heat exchangers that enable heat to be recovered from the outlet of the gasifier. The recovered heat is used to make the process steam as well as to preheat the hydrocarbon mix before it is fed to the gasifier and preheat the synthesis gas before it is fed to the Fischer-Tropsch reactor. The method of the present invention greatly increases carbon efficiency and reduces the generation of carbon dioxide.
