Abstract

A method for the continuous production of synthesis gas comprising carbon monoxide and hydrogen through the autothermal gasification of solid combustibles in a pressure reactor which comprises: PA1 introducing into a screw machine containing two parallely ordered shafts, a finely divided solid combustible, moistening and intimately mixing the solid combustible with 2 to 30% by weight of water, degasing and compressing the moist solid combustible to a pressure higher than that of the reactor, adding the gas-tight compressed and moist solid combustible to a reaction chamber-through a burner where the combustible is brought into contact with the gasification medium, thereby evaporating the water in the compressed and moist solid combustible and producing a comminuted dispersion of the solid combustible in the mixture of the gasification medium and water vapor; PA1 reacting the combustible dispersion to give a raw synthesis gas and removing the raw synthesis gas from the reactor.
