Abstract: A device for treating steam-saturated crude gases from the entrained flow gasification of fuels before entry into heat exchanges sited upstream of a crude gas converting operation. To avoid solid deposits in an entrance region of the heat exchangers, a crude gas is converted from a saturated into the superheated state by supply of hot gas. Hot gas contemplated is superheated high pressure steam or recycled superheated converted crude gas.

Abstract: A technology for producing synthesis gas from crude gas from various gasification processes for solid or liquid fuels. To limit the temperatures in a subsequent strongly exothermic CO shift reaction to adjust the H2/CO ratio, the crude gas which has been freed of dust flows through two shift reactors arranged in series. The first reactor has a specific reaction-kinetically limited catalyst and the second reactor has a conventional sour gas catalyst. The specific catalyst used in the first reactor limits the exothermic shift reaction to such an extent that the reaction temperatures in the first and second reactors remain so low to avoid thermal damage to the catalysts even without introduction of external steam, and the desired gas composition is achieved.

Abstract: A process for gasifying solid or liquid gasification materials, in particular biomass, at pressures in the range from atmospheric pressure to 10 MPa and at gasification temperatures in the range from 800° C. to 1500° C. to form a highly calorific synthesis gas. An endothermic steam gasification process proceeds in a gasification space of an entrained flow gasifier, and a plasma of intermediate temperature (typically <3500° C., preferably <2000° C.) introduces heat of reaction into the gasification space in such a quantity that the gasification temperature is kept below the ash softening temperature of 1500° C. Endothermic reactions, in particular reactions having a high activation energy, proceed at high rates at far lower gas temperatures than in the case of a thermal process. The gasification process, which does not require an oxygen plant, gives a crude gas which is free of hydrocarbons.
