Key Words:
chlorine, hydrogen chloride, catalytic oxidation
The invention discloses a manufacturing technical method of chlorine gas through catalyzing and oxidizing hydrogen chloride in the chemical technical course domain, wherein the technical flow path is composed of multiple groups of reactor and water separating device; the hydrogen chloride and oxygen are reacted in the reactor to generate chlorine gas and water under catalyst; the gas flowed out of the reactor is condensed in the water separating device to remove water and the non-condensed gas enters next reactor; the chemical balance is broken due to removing water, which is beneficial to continuously react the non-reacted hydrogen chloride and oxygen in the next reactor; the conversion rate of hydrogen chloride or oxygen approaches 100% after multiple groups of reaction and water removing operation. The invention has high conversion rate of hydrogen chloride or oxygen, simple equipment, which stabilizes the operation with easy control.
