Abstract | 2013P24521US Abstract Treatment of synthesis gases from a gasification facility The invention describes a technology for producing synthesis gas from the 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 reactors arranged in series, where the first reactor is provided with a specific reaction-kinetically limited catalyst and the second reactor is provided with 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 that thermal damage to the catalysts is ruled out even without introduction of external steam and the desired gas composition is achieved. |
