摘要:
Methods and systems related to augmenting syngas production using electrolysis are disclosed. A disclosed method includes harvesting a volume of carbon monoxide from a syngas production system operating on a volume of natural gas, supplying the volume of carbon monoxide to a cathode area of an electrolyzer, and generating, using the volume of carbon monoxide and the electrolyzer, a volume of generated chemicals. The volume of generated chemicals is at least one of: a volume of hydrocarbons, a volume of olefins, a volume of organic acids, a volume of alcohols, and a volume of N-rich organic compounds.

Disclosed are systems and methods having inherent carbon capture and conversion capabilities offering maximum flexibility, efficiency, and economics while simultaneously enabling environmentally and sustainably sound practices. A hybrid thermochemical cycle couples staged reforming with hydrogen production and residue chlorination. The residues of the upgrading are chlorinated, metals of interest are removed and bulk material is re-mineralized. Through the residue chlorination process, various metals including rare earths are concentrated and extracted. Energy is retained through chemical synthesis such as hydrocarbon and metal and non-metal chloride production. Produced chemicals are later exploited by redox reactions in the operation of an integrated gasification flow battery.
摘要:
A method and system for cost effectively converting a feedstock using thermal plasma, or other styles of gassifiers, into a feedwater energy transfer system. The feedstock can be any organic material, or fossil fuel. The energy transferred in the feedwater is converted into steam which is then injected into the low turbine of a combined cycle power plant. Heat is extracted from gas product issued by a gassifier and delivered to a power plant via its feedwater system. The gassifier is a plasma gassifier and the gas product is syngas. In a further embodiment, prior to performing the step of extracting heat energy, there is is provided the further step of combusting the syngas in an afterburner. An air flow, and/or EGR flow is provided to the afterburner at a rate that is varied in response to an operating characteristic of the afterburner. The air flow to the afterburner is heated.

System for processing material to generate syngas in a modular architecture may include a plurality of primary reactor chambers and a shared secondary reactor chamber. Each primary reactor chamber includes electrodes protruding into the chamber, the electrodes operable to generate an arc capable to generate first-stage gas from breakdown of the material when electricity is applied to the electrodes. The secondary reactor chamber is operable to receive the first-stage gas generated by the plurality of primary reactor chambers and to receive water vapour. The gas generated within the plurality of primary reactor chambers combine and interact with the water vapour to form second-stage gas. Turbulence can be generated within the secondary reactor chamber to improve mixing of the first-stage gas with the water vapour. Powering of each of the primary reactor chambers can be done with a different phase of power from a multi-phase input to ensure balanced power utilization.

摘要:
A rotating heat regenerator is used to recover heat from the syngas at it exits the reactor vessel of a waste or biomass gasifier. In some embodiments, three or more streams are passed through the heat exchanger. One stream is the dirty syngas, which heats the rotating material. A second stream is a cold stream that is heated as it passes through the material. A third stream is a cleaning stream, which serves to remove particulates that are collected on the rotating material as the dirty syngas passes through it. This apparatus can also be used as an auto-heat exchanger, or it can exchange heat between separate flows in the gasifier process. The apparatus can also be used to reduce the heating requirement for the thermal residence chamber (TRC) used downstream from the gasification system.

摘要:
A gasification system method and apparatus to convert a feed stream containing at least some organic material into synthesis gas having a first region, a second region, a gas solid separator, and a means for controlling the flow of material from the first region to the second region. The feed stream is introduced into the system, and the feed stream is partially oxidized in the first region thereby creating a solid material and a gas material. The method further includes the steps of separating at least a portion of the solid material from the gas material with the gas solid separator, controlling the flow of the solid material into the second region from the first region, and heating the solid material in the second region with an electrical means.
摘要:
Gasifiers that may be used for gasifying hydrocarbon-containing materials are disclosed. Methods for use of such gasifiers are also disclosed. In an embodiment, a gasifier includes a gasification reaction vessel having one or more electrodes positioned therein. The one or more electrodes may be used to alter a chemical and/or thermodynamic equilibrium of the gasification reaction. For example, the one or more electrodes may be used to make the oxidation zone more oxidizing and/or to make the reduction zone more reducing such that oxidation and/or reduction reactions are favored. Electrodes in such gasifiers may, for example, be used to alter the mix of products produced by the gasification reaction, to lower the gasification reaction temperature, to enable altering the dimensions of the gasifier (e.g., to make the gasifier smaller) without sacrificing efficiency, and/or to speed up startup and/or shutdown.
