Abstract: The invention relates to a process for obtaining hydrogen from natural gas which comprises (a) reacting the natural gas with a mixture of air and steam in a single reactor to obtain a gas comprising H2 and CO, (b) reacting the CO produced at a high temperature with steam to obtain a gas comprising H2 and CO2, and (c) reacting the CO which has not reacted in step (b) at a low temperature with steam to obtain a gas comprising H2 and CO2, characterized in that in step (a) the natural gas, the air and the steam are fed simultaneously and react on the same catalyst and in that the pressure used in steps (a) to (c) varies between 1 and 8 atm, as well as to a H2 production plant for carrying out the mentioned process.
