Patent ID: 8685282

Claim:
A process for the production of syngas and hydrogen starting from reagents comprising liquid hydrocarbons, gaseous hydrocarbons, and/or oxygenated compounds, also deriving from biomasses, and their mixtures, comprising: reacting said reagents with an oxidant including oxygen, air, or air enriched in oxygen to yield syngas in three sections for short-contact-time catalytic partial oxidation (SCT-CPO); cooling the syngas from outlets of said three sections for SCT-CPO in three thermal-recovery sections comprising a first thermal-recovery section for cooling the syngas in the output from a first SCT-CPO section and preheating the reagents to the temperature between 100Â° C. and 500Â° C. and a first boiler and a second boiler that generate steam by cooling the syngas produced respectively by a second SCT-CPO section and a third SCT-CPO section; separating the hydrogen using semipermeable membranes that operate at 450-500Â° C., each of said first thermal-recovery section and said first boiler being followed by a section for separation of the hydrogen using semipermeable membranes, said semipermeable membranes being constituted by metallic or non-metallic inorganic material; removing the carbon dioxide contained in the syngas and for recycling for conversion to syngas in the third SCT-CPO section; and cooling and removing condensate from the syngas in the third SCT-CPO section.
