METHOD OF MODERNIZATION IN PLACE OF REACTOR OF HETEROGENEOUS EXOTHERMIC SYNTHESIS, ESPECIALLY OF SO-CALLED KELLOG REACTOR, REACTOR OF HETEROGENEOUS EXOTHERMIC SYNTHESIS AND METHOD OF CONDUCTION OF HIGHLY-PRODUCTIVE HETEROGENEOUS REACTIONS Russian patent published in 2000 - IPC

Abstract RU 2154524 C2

FIELD: chemical industry. SUBSTANCE: method includes preliminary step for formation of at least three radial or axial-radial layers 11, 12 and 13 of catalyst, further steps for provision of the first gas-gas heat exchanger 18 between first 11 and second 12 layers of catalyst and of the second gas-gas heat exchanger 29 in third layer 13 of catalyst. Due to installation of two heat exchangers 18 and 29 designed for cooling of gases passing between catalyst layers by means of indirect heat exchange, the method results in obtaining of reactor with high conversion degree. EFFECT: higher efficiency. 17 cl, 2 dwg, 2 tbl
