Abstract

Reformador multitubular para un sistema de reformado de hidrocarburos y alcoholes integrado con una pila de combustible, que comprende un colector de alimentación y distribución de reactivos (1), unos tubos de reacción (6) alrededor de los que circulan unos gases calientes, al menos dos intercambiadores de calor y un colector de flujo de gas de reformado (18). La distribución del gas de reactivos se realiza de forma homogénea a todos los tubos de reacción (6) mediante una placa de distribución (5) situada en la brida de conexión (2) del colector (1) y a un anillo de restricción de flujo (3) situado en la línea de entrada de gas de reactivos que elimina la lateralidad del flujo de gas de reactivos antes de llegar a la placa de distribución (5). Es también objeto de la invención un sistema de reformado de hidrocarburos y alcoholes que comprende dicho reformador.
