method for mordenizzazione in situ to a reactor for heterogeneous exothermic synthesis, in particular, of the type known as kellogg

摘要

a method for the modernization "in situ" of a reactor for carrying out heterogeneous exothermic synthesis, in particular, of the type known as kellogg.including the preliminary phase to prepare at least three catalytic beds (11, 12, 13) for radial flow or assialeradiale.provides for the preparation of a first heat exchanger (18) gas / gas between the first (11) and the second (12) catalyst bed, and a second heat exchanger (29) gas / gas in the third bed.catalyst (13).thanks to the prediction of two heat exchangers (18, 19) for cooling the gas flowing between the catalytic beds by indirect heat exchange.the present method allows obtaining modernization a reactor with a high conversion yield.
