METHOD FOR PARTIAL CATALYTIC OXIDATION OF HYDROCARBONS FOR PRODUCING SYNTHETIC GAS WITH LOW H2/CO RATIO

摘要

The invention concerns a method for partial catalytic oxidation of an oxygenated gas (3) for producing a synthetic gas comprising at least H2 and CO in a H2/CO volume ratio ranging between 1 and 2.8 which consists in: adding to the hydrocarbon and the oxygenated gas at least an auxiliary gas (2) selected among CO2, H2O and CH4, and subjecting the gas mixture resulting from the partial oxidation reaction to a separation step (7, 9) during which the auxiliary gas (2) is separated from the rest of the mixture, then recycling said separated gas upstream of the process.
