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.

Device for the treatment of crude synthesis gas

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

Treatment of crude synthesis gas

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 H/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.
