Preparation of chlorine by gas-phase oxidation of hydrogen chloride by a gas stream having molecular oxygen in presence of a fixed-bed catalyst is carried out in reactor having bundle of parallel catalyst tubes and deflector plate

摘要

Preparation of chlorine involves passing hydrogen chloride and gas stream comprising molecular oxygen in a reactor (1) having parallel catalyst tubes (2) charged with fixed-bed catalyst and at least one deflector plate (6) perpendicular to the reactor. The plates leave passages on opposite sides of the reactor free next to its interior wall. A liquid heat transfer medium circulates between tubes.
