Claim Text:
1. A process for the production of synthetic gas by partial combustion of a carbonaceous feed in a gasification reactor at a pressure of between 25 to 60 barg, the method comprising the steps of: feeding a mixture of oxygen and the carbonaceous feed, the carbonaceous feed comprising pulverized coal, to the gasification reactor via one or more burners, while oil is atomized into the reactor via one or more oil lances, each comprising an atomizing nozzle comprising a coaxial arrangement of an oil channel and at least one adjacent steam channel; replacing up to 30% by weight of the pulverized coal of the carbonaceous feed with biomass having a lower heating value and compensating for the lower heating value of the biomass by co-feeding the oil via the one or more oil lances without decreasing the thermal efficiency of the reactor.
