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 CO<SUB>2 </SUB>containing transport gas ( 30, 32 ) is used to transport the solid carbonaceous fuel ( 8 ) to the burner wherein the weight ratio of CO<SUB>2 </SUB>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, CO<SUB>2</SUB>, and H<SUB>2 </SUB>( 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 ). |
