Abstract
Lump fuels are continuously coked at a high temperature above 750.degree. C in a shaft oven with direct heating by a hot scavenging gas which is produced by a partial combustion of the coking gas and conducted through the shaft oven in a countercurrent to the lump fuel. A reactive carbonaceous material is added to the hot scavenging gas before it enters the high-temperature coking zone and reacts with the gasifying agents (carbon dioxide and water) contained therein before it is introduced into the shaft oven.
