摘要:
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.
摘要:
A system includes a gasifier having a first enclosure having a first inlet, a first outlet, and a first interior volume. The first inlet is configured to receive a first fuel feedstock into the first interior volume, and the first outlet is configured to output a first syngas away from the first interior volume. The system also includes a plasma gasifier disposed downstream from the first outlet and coupled to a waste stream produced by the gasifier from the first fuel feedstock.
摘要:
A method for generation of power and Fischer-Tropsch synthesis products by producing synthesis gas comprising hydrogen and carbon monoxide, producing Fischer-Tropsch synthesis products and Fischer-Tropsch tailgas from a first portion of the synthesis gas, and generating power from a second portion of the synthesis gas, from at least a portion of the Fischer-Tropsch tailgas, or from both. The method may also comprise conditioning at least a portion of the synthesis gas and/or upgrading at least a portion of the Fischer-Tropsch synthesis products. A system for carrying out the method is also provided.
摘要:
A method for purification and conditioning of crude syngas based on properties of molten salts, includes removing particles at a high-temperature by enabling the high-temperature crude syngas produced by a gasification device to firstly pass through a high-temperature particle removal device to remove solid particles in the gas; removing hydrocarbons in the presence of oxygen by introducing an oxidant into the crude syngas after treatment, selectively removing the hydrocarbons in the crude syngas and simultaneously utilizing high temperature produced by oxidation of the hydrocarbons to crack tar; and removing gas pollutants and conditioning by introducing the obtained crude syngas into molten salts medium, removing pollutants containing sulfur and chlorine in the crude syngas, and simultaneously adjusting the H2/CO ratio of the syngas to obtain purified syngas.

摘要:
A process and related apparatus for the treatment of hazardous waste and an initially separate waste stream, the process comprising gasifying the waste stream in a gasification unit to produce an offgas and a char material; and plasma treating the offgas, and optionally the char material, in a plasma treatment unit to produce a syngas; and blending hazardous waste with the waste stream at a point in the process determined by the relative chemical and/or physical properties of the hazardous waste and the waste stream.

摘要:
A multi-zone carbon converter for converting processed feedstock to syngas and slag is provided comprising a chamber comprising a carbon conversion zone in communication with a slag zone for melting ash into molten slag and/or for maintaining slag in a molten state by the application of plasma heat. The carbon conversion zone and the slag zone are separated by the inter-zonal region that comprises an impediment for restricting or limiting the movement of material between the two zones. The inter-zonal region may also provide for the initial melting of the ash into molten slag by affecting the transfer of plasma heat from the slag zone.
摘要:
An equilibrium approach reactor with the ability to receive a highly variable gas and normalise it to a useful quality, and further to utilise the energy from the gas itself to robustly elevate the operating temperature, to ensure good mixing and high conversion while having the ability to handle solids in multiple states.
