Abstract
A plurality of catalyst disks pressed from porous catalyst material are stacked one on the other and together sintered with the application of pressure to make a stacked reactor for hydrogen production from hydrocarbons. To form especially tight seams the catalyst disks have projections formed in the area of contact with an adjacent catalyst disk. Hollow spaces formed in the catalyst disk or formed by two adjacent catalyst disks have a system for supporting the hollow spaces, as for example a cooper grid placed in the hollow space, which can be covered at least partially by a metal sheet or supporting bars pressed onto the catalyst disk.
