Abstract
A method for in-situ modernization of a reactor for carrying out heterogeneous exothermic synthesis reactions, in particular of the so-called lozenge type including an external shell (2), calls for prearrangement within the shell (2) of a plurality of superimposed catalyst beds (12, 13, 14) supported at a pre-set distance by means of support elements (22, 23, 24) rested on or fixed to, e.g. by welding, a plurality of annular shoulders (8a, 8b, 8c) pre-existing in the reactor.
