A B S T R A C T PROCESS FOR THE PREPARATION OF HYDROCARBONS AND A FUEL GAS Process for the preparation of hydrocarbons and a fuel gas from a heavy carbonaceous feedstock, which process comprises: a) cracking the heavy carbonaceous feedstock in a coking zone which contains a bed of fluidized solids, producing hydro carbons and coke which deposits upon the fluidized solids; b) introducing a part of the coke-containing solids into a gasification zone in which at least a part of the coke is gasified with an oxygen-containing gas yielding a c carbon monoxide- and hydrogen-containing gas mixture; c) partially converting the carbon monoxide- and hydrogen-con- taining gas mixture into hydrocarbons in a synthesis zone; d) separating a fuel gas comprising carbon monoxide, hydrogen and gaseous hydrocarbons, and at least one liquid hydrocarbon fraction from the product of the synthesis zone.
