A process for the production of syngas and hydrogen starting from liquid hydrocarbons, gaseous hydrocarbons and/or oxygenated compounds, also deriving from biomasses, and mixtures thereof, envisages recourse to a membrane reactor in an architecture that uses a succession of reaction and separation stages. Said process comprises a section for pre-heating the reagents, a number of sections for short -contact -time catalytic partial oxidation for producing syngas and hydrogen in a number of stages followed by a separation of hydrogen produced by means of membranes, a thermal -recovery section, a section.for removal of the carbon dioxide produced, and a section for cooling and removal of the condensate. Possibly, said process comprises a section for purification of hydrogen obtained by means of pressure -swing adsorption (PSA) and generation of purge gas with medium calorific value. Furthermore, said process comprises a section for hydrodesulphuration of the reagents and could comprise a section for conversion of the CO2 and H2 produced by means of a reverse-water-gas-shift (RWGS) reaction. |
