Abstract: A catalyst composition suitable for the ethanol reforming process at low temperature with enhanced stability on long term, comprises a noble metal, such as platinum or rhodium, and a transition non-noble metal, such as nickel or cobalt, supported by a carrier comprising, cerium, zirconium, optionally aluminium, supplemented with potassium. It is provided also a method for the stable production of hydrogen from an ethanol containing gas stream, comprising subjecting the gas stream to catalytic ethanol reforming as to form a rich H2 stream, using the catalyst as defined above.

Abstract: Method for stable ethanol steam reforming, wherein a catalytic ethanol reforming is carried out in two vessels operating in parallel mode both filled in with a catalyst active for this reaction, with the first vessel acting in operation mode, generating an hydrogen rich stream, and the parallel vessel, acting in regeneration mode, made flowing with steam in order to carry out the gasification of carbonaceous compounds deposited on the catalyst.

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.
