  • Patent number: 8932774
    Abstract: The present invention relates to a catalyst for producing gaseous hydrogen current or hydrogen-rich currents through hydrocarbon reforming with water vapor. Said catalyst comprises at least one support, an active phase and at least two promoting agents, and is characterized in that it is a metal-type-supported solid in which the active phase comprises at least one transition metal chosen from group VIII, and at least one promoting agent chosen from the alkaline-earth or transition metals; and the support comprises at least one mixed oxide with a basic nature, and at least one promoting agent chosen from among the lanthanides group. The invention also has as an object the process for preparing the catalyst, as well as its use in the process for obtaining the hydrogen or hydrogen-rich gas from hydrocarbons, in different operating conditions and using various types of hydrocarbons.

  • Patent number: 8663857
    Abstract: The present invention relates to a process for producing a continuous flow of hydrogen by catalyzed hydrolysis of a complex hydride, which comprises at least adding continuously and at constant rate a fuel solution to a reactor comprising a complex hydride stabilized on a hydroxide on a cobalt boride catalyst that is added in excess inside said reactor. Sodium borohydride is preferably used, the hydroxide is sodium hydroxide and the catalyst is supported on nickel foam. Parameters and optimal conditions to achieve continuous production of hydrogen have been determined, which is essential in the operation of fuel cells. A facility comprising a semi continuous reactor designed to perform the above process, which needs no refrigeration is also an object of the present invention, as well as a washing and reactivation process of a catalyst of the type used in the process mentioned above.
