Abstract
Process for preparing a hydrocarbon product from a solid carbonaceous fuel (8), the process at least comprising the steps of: (a) supplying a solid carbonaceous fuel (8) and an oxygen containing stream (9) to a burner of a gasification reactor (10), wherein a CO2 containing transport gas (30, 32) is used to transport the solid carbonaceous fuel (8) to the burner wherein the weight ratio of CO2 to the carbonaceous fuel in step (a) is less than 0.5 on dry basis.; (b) partially oxidising the carbonaceous fuel in the gasification reactor, thereby obtaining a gaseous stream at least comprising CO, CO2, and H2 (11); (c) removing the gaseous stream obtained in step (b) from the gasification reactor; (d) optionally shift converting (16) at least part of the gaseous stream as obtained in step (c) thereby obtaining a CO depleted stream, (e) subjecting the gaseous stream of step (c) and/or the optional CO depleted stream of step (d) to a Fischer-Tropsch reaction to obtain a hydrocarbon product (24).
