METHOD FOR THE PRODUCTION OF CHLORINE BY MEANS OF GAS PHASE OXIDATION OF HYDROGEN CHLORIDE

摘要

Disclosed is a method for producing chlorine by means of gas phase oxidation of hydrogen chloride with a gas flow containing molecular oxygen in the presence of a fixed-bed catalyst. Said method is carried out in a reactor (1) comprising a nest of contact tubes (2) that are disposed parallel to each other in the longitudinal direction of the reactor and are fastened within tube bottoms (3) at the ends thereof, a hood (4) that is arranged at both ends of the reactor (1), and one or several deflecting metal sheets (6) which are disposed perpendicular to the longitudinal direction of the reactor in the intermediate space (5) between the contact tubes (2) and alternately release opposite passages (7) located on the inner wall of the reactor (1). The contact tubes (2) are filled with the fixed-bed catalyst, the hydrogen chloride and the gas flow containing molecular oxygen are directed from one end of the reactor through the contact tubes (2) via a hood (4) and are withdrawn from the opposite end of the reactor via the second hood (4), and a liquid heat-exchanging substance is directed through the intermediate space (5) around the contact tubes (2).
