TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The feedstock comprises mineral components thus causing the gasification gases to undergo purification as they move through the combustion and reforming zones. The sorbent is a metal, oxide, salt, or oxide hydrate. The flux is a metal, oxide, salt, oxide hydrate, sulfide, or chloride.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The gasifier boot: is characterized by an axis and further comprises an upper end, a lower end, and many slits located along the gasifier boot, where each of slit is characterized by a width of the lower slit end that is greater than a width at the upper slit end, and is positioned substantially along the length of the gasifier boot; the gasifier boot is further characterized by a cross-section of the lower end perpendicular to the axis and a cross-section of the upper end perpendicular to the axis, where cross-section of the lower end is greater than the cross-section of upper end. The damping chamber: is formed between the gasifier boot and elongated internal vessel; and formed so as to channel gases from the feedstock into the fire chamber. The apparatus further comprises: at least one rigidity rib located on the outside surface of the gasifier boot between adjacent slits of many slits, where at least one rigidity rib is positioned substantially along the gasifier boot; at least one feedstock breaker located onthe inside surface of the gasifier boot immediately above the fire chamber; at least one rigidity structure positioned on the outside surface of the gasifier boot so as to counter the pressure from the feedstock as it is moving inside the gasifier boot; and a gas turbulator located between the elongated external vessel and elongated internal vessel. The slag discharge mechanism further comprises a slag scraper, an air cooling system, and a water cooling system. The feedstock feeder is a piston. Preferred Method: The method further comprises: causing the separated pyrolysis gases and the steam to form a mixture; causing the mixture to move to the combustion zone; burning the mixture in the combustion zone; burning a portion of the carbon char residue in the combustion zone; using a remaining portion of the carbon char residue for reforming reactions in the reforming zone; supplying air, mixture of oxygen and steam to the combustion zone, where the air is heated at least 100F, and supplied at a velocity not exceed 60 meters per second; causing substantially all hydrocarbons contained in the pyrolysis gases to convert into hydrogen and carbon monoxide while moving through the combustion zone and to reforming zone; adding to the feedstock at least one sorbent, at least one flux and silicon dioxide; supplying steam and carbon dioxide into combustion zone; causing the gasification gases to move about at least one of the reforming zone, combustion zone, pyrolysis zone, plasticization zone or drying zone thus reducing a temperature of the gasification gases.
