<p>A catalyst-seal support device, in particular for an exothermic heterogeneous catalytic synthesis reactor comprising at least one catalytic bed (5a-5c) arranged in a cylindrical shell (2) and provided with a bottom plate (6a-6c) for containment of the catalyst, and at least one supporting shoulder (7a-7c) for the bottom plate (6a-6c) extending from the shell (2), comprises an annular element (17-25) placed between the shoulder (7a-7c) and the bottom plate (6a-6c). The annular element (17, 25) is associated in a removable manner with the bottom plate (6a-6c) and has a thermal expansion coefficient substantially equal to that of the shell (2).</p> |
