PROCESS FOR THE CHLORINE BY OXIDATION OF HYDROGEN CHLORIDE

摘要

The present invention relates to a method for preparing chlorine by decomposing hydrogen chloride, in which hydrogen chloride is reacted with oxygen containing gas in the presence of a cerium based catalyst at comparatively low temperature of up to 400°C to produce chlorine. The cerium based catalyst of the present invention maintains its catalytic activity for a long time, compared with other catalysts prepared by the conventional processes, has excellent stability at high temperature, and has high economical efficiency, so that it paves the way to the development of an economically excellent oxidative decomposition process to produce chlorine from hydrogen chloride.
