Abstract: Disclosed is a process for the production of a syngas mixture by catalytic partial oxidation. The syngas mixture is suitable as an intermediate in the production of hydrogen. According to the invention, the syngas is cooled, prior to a water gas shift reaction, with liquid water. This has the advantage of avoiding the problem of metal dusting, and it presents a gas mixture comprising water vapor that is particularly suitable for a water gas shift reaction in the production of hydrogen.

Abstract: 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. The process includes 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 separation of hydrogen produced via membranes, a thermal-recovery section, a section for removing produced carbon dioxide, and a section for cooling and removing condensate. Optionally, the process includes a section for purifying obtained hydrogen via pressure-swing adsorption (PSA) and generating purge gas with medium calorific value.

Abstract: Disclosed is a process for the catalytic dehydrogenation of alkanes so as to form the corresponding olefins. The reaction mixture is subjected to membrane separation of hydrogen, in a separate unit. Preferably a plurality of alternating reaction and separation units is used. The process of the invention serves the purpose of reducing coke formation on the catalyst, and also of achieving a higher alkane conversion without a similar increase in coke formation. The process can also be used for the production of hydrogen.

Abstract: The present invention relates to a process for the production of hydrogen starting from liquid hydrocarbons, gaseous hydrocarbons, and/or oxygenated compounds, also deriving from biomasses, and mixtures thereof. Said process is characterized in that it comprises a preheating section (200) of the reagents, a short contact time—catalytic partial oxidation section (101) to give synthesis gas, a thermal recovery section (201), a conversion section (102) of the carbon monoxide present in the synthesis gas to carbon dioxide by means of a Water Gas Shift reaction, a removal section of the carbon dioxide produced (104), a cooling and removal section of the condensate. Said process can possibly comprise a purification section of the hydrogen produced by means of Pressure Swing Adsorption (105) and generation of purge gas having a medium heat power. Said process also possibly comprises a hydrodesulphuration section of the reagents.
