Abstract: Pre-ground plastics of small particle size not more than 2 mm are co-fed into a solid fossil fuel fed entrained flow partial oxidation gasifier. A syngas composition can be made by charging an oxidant and a feedstock composition comprising recycle plastics and a solid fossil fuel to a gasification zone within a gasifier; gasifying the feedstock composition together with the oxidant in said gasification zone to produce said syngas composition; and discharging at least a portion of said syngas composition from said gasifier; wherein the recycled plastics are added to a feed point comprising a solid fossil fuel belt feeding a grinder after the solid fossil fuel is loaded on the belt, a solid fossil fuel belt feeding a grinder before the solid fossil fuel is loaded onto the belt, or a solid fossil fuel slurry storage tank containing a slurry of said solid fossil fuel ground to a size as the size fed to the gasification zone.

Abstract: Methods and pyrolysis plants are described, comprising reactors for producing pyrolysis gas from biomass. The reactors comprise one or more reaction channels linked thermally with at least one heating circuit, which is configured to heat the reaction channels to a temperature that is high enough to gasify the biomass. The reactors comprise a feed section configured for feeding the biomass into the reaction channels. The pyrolysis plants comprise a gas accelerator configured for recirculating the gas that is present in the at least one reaction channel and for providing a gas flow velocity that is able to distribute the biomass in the reaction channel.

Abstract: A carbonaceous fuel gasification system for a supercritical CO2 power cycle system includes a micronized char preparation system comprising a devolatilizer that receives solid carbonaceous fuel, hydrogen, oxygen, and fluidizing steam and produces micronized char, steam, hydrogen, and volatiles. An indirect gasifier includes a vessel comprising a gasification chamber that receives the micronized char, a conveying gas, and steam where the gasification chamber provides syngas, ash, and steam. A combustion chamber receives syngas and an oxidant and burns the mixture of syngas with the oxidant to provide heat for gasification and for heating incoming flows, thereby generating steam and CO2. The heat for gasification is transferred from the combustion chamber to the gasification chamber by circulating refractory sand. A syngas cooler cools the syngas and generates steam and provides to a supercritical CO2 power cycle system that performs a supercritical CO2 power cycle for generating power.

Abstract: A chemical looping combustion (CLC) based power generation, particularly using liquid fuel, ensures substantially complete fuel combustion and provides electrical efficiency without exposing metal oxide based oxygen carrier to high temperature redox process. An integrated fuel gasification (reforming)-CLC-followed by power generation model is provided involving (i) a gasification island, (ii) CLC island, (iii) heat recovery unit, and (iv) power generation system. To improve electrical efficiency, a fraction of the gasified fuel may be directly fed, or bypass the CLC, to a combustor upstream of one or more gas turbines. This splitting approach ensures higher temperature (efficiency) in the gas turbine inlet. The inert mass ratio, air flow rate to the oxidation reactor, and pressure of the system may be tailored to affect the performance of the integrated CLC system and process.

Abstract: A gasification burner for a multiple-burner arrangement in an entrained-flow gasifier, in which the gasification burner extends along a main axis and in which the media for the gasification reaction in the gasification burner are guided in separate media channels and exit at the burner mouth in a direction having an angle to the main axis that is not zero. A vertical installation with an optimally adaptable flame shape is provided. Depending on the orientation of the burners, the flame shape is adaptable, whether it be a minimized total flame diameter for an initial slag formation of the cooling screen or an increase in the total twist of the total flame for an increased particle deposition on the reactor wall. The gasification burner with angled burner tips can be used as part of a retrofit.

Abstract: This invention is about a coal feeding system (1) which feeds pulverized coal and oxygen separately and vertically through concentric pipes directly to the upper level of the reactor (R) at entrained flow gasification systems. The system (1) consists a top intake (2), a side intake (3), an air supply chamber (4), an oxygen port (5), an ultrasonic sensor port (6), an inner concentric pipe (7), and an outer concentric pipe (8). The system (1) also operates with a coal bunker (K), a screw feeder (B) for adjusting the coal mass flow rate from the coal bunker (K) through the coal feeding system (1) to the reactor (R), and a reactor (R) where the coal are sprayed from the coal feeding system (1) and gasified at high temperatures.
