Abstract A process for preparing hydrogen (H2) includes such steps as partial oxidization of the gas mixture of metane, ethane, propane and butane in the presence of Ni/Si-2 catalyst modified by rare-earth and alkali-metal oxide, conversion reaction of water vapour, and pressure swing adsorption or membrane separation. Its advantages are high conversion (about 100%) of C2H6, C3H8 and C4H10, low energy consumption and high selectivity of H2.
