Process and Plant for the Gasification of Solid Carbonaceous Substances

摘要

In the process a portion of the methane of the product gas is decomposed under the action of steam, to obtain the hydrogen containing gasification agent, at least a predominant portion of the decomposition apparatus being heated by the heat of combustion of the residual coke produced during gasification. The residual coke originates from a fluidized layer reactor (14) whereby gasification and combustion are adjusted to one another. Also the use of such a reactor (14) allows for compact construction and thus lower prime costs. Further by means of a fluidized layer reactor (14) a uniform temperature is maintained over the entire fluidized layer so that there is no risk of overheating particular regions of the decomposition apparatus (26).
