The present invention relates to a process for producing synthesis gas or a hydrocarbon product from a carbonaceous fuel, the process at least comprising the steps of : (a) supplying a carbonaceous fuel and an oxygen containing stream to a burner of a gasification reactor, wherein a CO2 containing transport gas is used to transport the solid carbonaceous fuel to the burner; (b) partially oxidising the carbonaceous fuel in the gasification reactor, thereby obtaining a gaseous stream at least comprising CO, CO2, and H2 ; (c) removing the gaseous stream obtained in step (b) from the gasification reactor; wherein the weight ratio of CO2 to the carbonaceous fuel in step (a) is less than 0.5 on a dry basis.
