    Abstract: This invention relates to a method and a reactor for gasifying a carbonaceous feedstock material. The method includes the steps of choke-feeding a carbonaceous feedstock material into a pyrolysis zone of the reactor to form a discharge bed; heating the discharge bed to initiate pyrolysis of the feedstock material to form a pyrolysis product; providing a lower lying upper oxidation zone; gasifying the pyrolysis product to form a bed of char; converting thermal energy into chemical energy in an upper reduction zone; providing a lower lying lower oxidation zone; collecting any metal slag and/or slag melts in the lower oxidation zone; and discharging hot reducing gases having a temperature of at least 1300° C. and a CO/CO2 ratio of ≥5, more preferably ≥15.

    Abstract: 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.

    Abstract: A hybrid plasma reactor system that uses multiple sets of long electrodes that are placed longitudinally opposite each other within modular plasma units. The plasma units can be stacked to form an elongated plasma zone. The electrode assemblies extend into access ports. Each of the electrode assemblies has an electrode tip mounted in a tubular support jacket. A gas conduit for a supplied working gas surrounds at least a portion of the tubular support jacket. An arc is created at the electrode tip. A working gas flows through the gas conduit and is directed into the arc, therein creating plasma within the internal plasma zone.

    Abstract: A chemical reactor and a method for arranging a ceramic barrier in a gasifying reactor, which reactor is arranged to convert high energy organic waste of black liquor type with a large amount of organic or inorganic alkali metal compounds, by high temperature oxidation with air or oxygen, whereby the organic waste is converted to a hot reducing gas containing a considerable amount of water vapour and the inorganic compounds form an alkali-containing salt melt at a temperature of 750-1150° C., and which reactor is arranged to comprise an outer shell (14) with associated inlet and outlet devices for reactants and products, the method comprising the arranging of a lining (16, 18) comprising one or more layers of ceramic barriers (16, 18) on the inside of the shell (14), the innermost ceramic barrier (16) of the reactor being composed of a lining material that primarily contains compounds of aluminium oxide (Al2O3), and at least one of alkali metal oxides (Me2(I)O) and alkaline earth metal oxides (Me(I)0), forming compounds of the type Me2(I)O Al2O3 and Me(II)0-Al2O3.
