摘要： A reactor enables gasification or melting of waste and additional feed materials. The reactor includes a co-current section with a plenum section and a feed section with a sluice. Feed materials are introduced into the reactor. The reactor further includes a buffer section and a pre-treatment section, which adjoins a bottom of the buffer section to create a cross-sectional enlargement. An intermediate section adjoins the pre-treatment section. An upper oxidation section adjoins a bottom of the intermediate section and includes tuyeres in at least one level. An upper reduction section adjoins a bottom of the upper oxidation section. The reactor further includes a gas outlet section. The reactor further includes a countercurrent section having a conical lower reduction section and a conical lower oxidation section adjoining the conical lower reduction section having at least one tuyere and at least one tapping.

摘要： A method and system for continuous production of contaminant free and size specific biochar using downdraft gasification of variable quality feedstock. The system and process of the present invention includes the transfer of biochar from a gasifier after gasification to a temperature-controlled cooling screw conveyor, into a drum magnet for ferrous metal removal into multiple diverters to separate and remove ungasified materials and non-ferrous metal contaminants, then transferred into a granulator for grinding and screening the biochar to a pre-selected size. By directly attaching a novel and continuous product treatment process to the biochar stream as it exits the gasifier, the particle size, moisture content, carbon content and yield of a contaminant free biochar product can be narrowly controlled and improved to meet strict product quality specifications required by specialty applications.

摘要： A fixed bed gasifier has a clinker breakup device. The tapping element of the clinker breakup device can be positioned at different points, allowing the tapping element to be small but capable of reaching all regions of the fuel particle bed. The tapping element intermittently enters the fuel particle bed in gasifying operation. Before it re-enters the bed, the drive mechanism adjusts the position of the tapping element so that it does not enter the same tapping channel again. Repeated local spiking at different times and locations moves the gasifier bed and disrupts the sintering of clinker particles that can block the gasifier cross section. Gas continues to flow through individual zones over the entire cross section, and not just in the tapped channel. Lumps of clinker that have sintered together are conveyed onward—toward the support device—or else broken up.

摘要： The present invention discloses a gasifier and/or a gasification process that provides a long, uniform temperature zone in the gasifier, regardless of the particle size, chemical composition, and moisture content of the fuel by sandwiching a reduction zones between two oxidation zones. The gasifier and/or gasification process has a char that is more energy-dense and almost devoid of moisture that affords for an additional (or char) oxidation zone with a temperature that is higher than a first oxidation zone which is closer to an evaporation and devolatilization zone. As such, the additional (or char) oxidation zone contributes to augmenting the reduction zone temperature, thereby providing a favorable dual impact in improving syngas composition and near-complete conversion of the tar.

摘要： A method of producing oil, gas, and ash fertilizer from a feedstock includes inputting the feedstock into a reaction chamber having a wall, and combusting the feedstock in the reaction chamber. An electrical current flow is induced between the reaction chamber wall and the feedstock so as to cause arcing in the feedstock within the reaction chamber. Ash reaction byproducts migrate downward through the reaction chamber onto ash support structure, which is substantially electrically isolated from the reaction chamber wall. Gas and liquid reaction byproducts migrate upward through the reaction chamber to an upper chamber by a partial vacuum in the upper chamber, and are evacuated therefrom. The oil and gas are then separated from the evacuated gas/liquid products, providing the oil and the gas products. The oil is refinable, the gas is high in energy content, and the ash fertilizer is high in nitrogen.

摘要： A downdraft gasifier and method of gasification with high yield biochar that utilizes a plurality of high throughput, vertically positioned tubes to create a pyrolysis zone, an oxidation zone beneath the pyrolysis zone and a reduction zone beneath the oxidation zone. A rotating and vertically adjustable rotating grate is located beneath the reduction zone of the gasifier. In addition, a drying zone is located above the pyrolysis zone so the heat of the gasifier can be used to dry feedstock before it enters the gasifier. By optimizing the grate height and rpm, feedstock retention time in the drying zone, the drying zone temperature and feedstock moisture content, the result is gasification of biomass with a high yield and continuous biochar production.

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.
