Synthesis gas is produced from a carbonaceous fuel, using a process in a gasification reactor. The carbonaceous fuel and an oxygen containing stream are supplied to a burner of a gasification reactor, wherein a CO2-containing transport gas is used to transport the solid carbonaceous fuel to the burner. The weight ratio of CO2 to the carbonaceous fuel is less than 0.5 on a dry basis. The carbonaceous fuel is partially oxidized in the gasification reactor, whereby a gaseous stream of synthesis gas is obtained. This synthesis gas can be further processed in a downstream process path to convert it into a hydrocarbon product. The downstream process path may contain a methanol-synthesis reactor to produce the hydrocarbon product in the form of methanol. The downstream process path may contain a Fischer-Tropsch synthesis reactor to produce one or more from a range of hydrocarbon products.
