Abstract:
1. Process for the production of a gaseous mixture containing at least hydrogen (H 2 ) and carbon monoxide (CO) starting from at least one hydrocarbon selected from the group consisting of methane, ethane, a mixture of methane and ethane, and a mixture of butane and propane in which: (a) a partial catalytic oxidation without moderating agents of said at least one hydrocarbon is done at a temperature of less than 1200° C., at a pressure of 3 to 20 bars in the presence of a catalyst and oxygen or a gas containing oxygen, to produce hydrogen (H (b) a gaseous mixture containing at least hydrogen (H (c) the gaseous mixture obtained in step (b) is cooled to a temperature of between −20° C. and +80° C.; (d) the gaseous mixture obtained in step (c) is separated in order to produce a hydrogen rich gas flow and a waste gas flow; and in which a gaseous mixture at a pressure of 3 to 20 bars is obtained from step (b) and/or step (c).
