VERFAHREN ZUR KATALYTISCHEN ENTFERNUNG VON CHLORKOHLENWASSERSTOFFEN AUS DEPONIEGASEN

摘要

A process for removing chlorinated hydrocarbons from gases containing chlorinated hydrocarbons, whereby the gas flow which is to be cleaned is fed through a reactor (2) which contains a dehydrochlorination catalyst and an alkaline material. The reaction is performed at temperatures of 200-600<o>C and flow rates of 0.01-0.6 m/s. The dehydrochlorination catalyst may be in the form of activated carbon, aluminium oxide, silica gels or zeolitic molecular sieves which are impregnated with calcium, barium, copper or cobalt salts representing 2-20% by weight.
