Gasifying carbonacenous material

摘要

In gasifying carbonaceous material to a gas mixture consisting primarily of CO and H2 and desirably having a total content of CO2 and H2 less than 12%, carbonaceous material in lump form is supplied via a sluice arrangement (6) to a reactor (1) from above to a predetermined filling level. The gas produced is withdrawn from the reactor (1) at a level located below the upper surface (10) of the carbonaceous material. Oxidant and/or thermal energy is supplied both (8, 9) above the surface (10) of the carbonaceous material in lump form and also (2) at a lower level in the reactor (1), located below the level of the gas outlet (5).
