Summary: | 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.
Proceso de producción de hidrógeno mediante hidrólisis catalizada de un hidruro complejo, e instalación con reactor semicontinuo para llevar a cabo el procedimiento.La presente invención se refiere a un proceso para la producción de un flujo continuo de hidrógeno mediante hidrólisis catalizada de un hidruro complejo, que comprende al menos agregar de forma continua y a velocidad constante a un reactor una solución combustible que comprende un hidruro complejo estabilizado en un hidróxido, sobre un catalizador de boruro de cobalto que se adiciona en exceso dentro de dicho reactor. Preferentemente se emplea borohidruro sódico, el hidróxido es de sodio y el catalizador se encuentra soportado en espuma de níquel. Se han determinado los parámetros y condiciones óptimos para conseguir la producción continua de hidrógeno, fundamental en el funcionamiento de pilas combustible. También es objeto de la presente invención una instalación que comprende un reactor semicontinuo diseñado para llevar a cabo el proceso anterior, que no precisa refrigeración, así como un proceso de lavado y reactivación de un catalizador del tipo empleado en el proceso mencionado anteriormente. |
