The present invention relates to a process for the endothermic gasification of solid carbon in the entrained bed facility with hot gas from the partial oxidation of a process combination consisting of the process stages of partial oxidation of fuels and endothermic gasification of solid carbon which, if necessary, is preceded by low temperature carbonisation such that the carbonisation gas is passed to partial oxidation and the carbonisation coke to endothermic gasification, the hot gas streaming downwards from the combustion chamber in the process being deflected, according to the invention, with separation of the liquid slag and passed to the process stage of endothermic gasification of solid carbon, which operates with a rising gas stream, with an addition of solid carbon, preferably coke carbon from an in-process low temperature carbonisation and with a grain diameter of up to 20 mm, the speed of the gas at the carbon inlet being higher than and at the end of the process stage of the endothermic gasification lower than the suspension rate of the reactive carbon particles.
