Processes for producing high biogenic concentration Fischer-Tropsch liquids derived from the organic fraction of municipal solid wastes (MSW) feedstock that contains a relatively high concentration of biogenic carbon (derived from plants) and a relatively low concentration of non-biogenic carbon (derived from fossil sources) wherein the biogenic content of the Fischer-Tropsch liquids is the same as the biogenic content of the feedstock.

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.

Provided are a method for producing an organic substance and a device for producing an organic substance that are capable of efficiently cooling a synthesis gas and of converting the synthesis gas to an organic substance at a high conversion efficiency using a microbial catalyst. A thermally decomposed gas purification/cooling device including a gasification furnace 10 that gasifies waste to generate a thermally decomposed gas, a cyclone 11 through which the thermally decomposed gas discharged from the gasification furnace 10 is passed to recover a dust component in the thermally decomposed gas, and a heat exchanger 20 through which the thermally decomposed gas that has passed through the cyclone 11 is passed to be cooled.

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.

The present invention provides a process and apparatus for converting feedstock comprising biomass and/or carbon-containing solid waste material to synthesis gas. The process comprises supplying the feedstock to a gasifier comprising a fluidized bed zone and a post-gasification zone and contacting the feedstock with a gasification agent at a plurality of different operating temperatures based on the ash softening temperature of the feedstock and finally recovering the synthesis gas. The apparatus is configured to perform the process and comprises a plurality of nozzles arranged at an acute angle relative to a horizontal plane of the gasifier.

Systems and methods are provided for integrated pyrolysis and gasification of a biomass feed, either as a separate feed or under co-processing conditions. The integrated pyrolysis and gasification can be performed using any convenient reactor configuration, such as fluidized coking reactor configuration or a fluid catalytic cracking reactor configuration. The biomass feed can initially by pyrolyzed to form liquid products, gas phase products, and char. The char can then be used as the input feed to gasification. In aspects where the biomass feed is co-processed, the biomass can be co-processed with a co-feed that is suitable for processing under fluidized coking conditions or other pyrolysis conditions, such as a conventional fluidized coking feedstock.

An ASG system for polygeneration with CC includes a devolatilizer that pyrolyzes solid fuel to produce char and gases. A burner adds exothermic heat by high-pressure sub-stoichiometric combustion, a mixing pot causes turbulent flow of the gases to heat received solid fuel, and a riser micronizes resulting friable char. A devolatilizer cyclone separates the micronized char by weight providing micronized char, steam and gases to a gasifier feed and oversized char to the mixing pot. An indirect fluid bed gasifier combustion loop includes a gasifier coupled to the gasifier feed, a steam input to provide oxygen for gasification and to facilitate sand-char separation, and an output for providing syngas. A burner provides POC to a mixing pot which provides hot sand with POC to a POC cyclone via a riser, where the POC cyclone separates sand and POC by weight and provides POC and sand for steam-carbon reaction.

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.

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.
