摘要： A process of producing chlorine gas by catalytic oxidation of hydrogen chloride is disclosed, and said process is characterized in that it comprises: incorporating an oxidizing agent such as ozone, hydrogen peroxide solution etc. into a gas stream of hydrogen chloride containing impurities, conducting oxidation pretreatment of said gas stream under the action of ultrasonic wave, such that said impurities contained in said gas stream are oxidized; wherein the oxidizing agent does not generate additional or new impurities in the reaction system. The gas stream obtained after the oxidation pretreatment is allowed to pass through a separating device wherein the oxidized impurities in the form of liquid and/or the oxidized impurities in the form of solid are removed from said gas stream so as to obtain a purified gas stream of hydrogen chloride. Thereafter, the purified gas stream of hydrogen chloride is well mixed with a gas stream containing molecular oxygen, the resultant gas mixture is preheated to a reaction temperature, and then catalytically oxidized to produce chlorine gas. By means of oxidation pretreatment and separation, the process can remove efficiently the sulfur-containing impurities, the halogen-containing impurities, hydrocarbon impurities and the like from the gas stream of hydrogen chloride, and does not generate additional impurities. Meanwhile, the present invention has an advantage of simple and convenient operation.

Mixing of the reactants in the reactor is improved such that the probability of producing burble is reduced and the negative pressure generated at the local jet area is eliminated, and the back mixing is reduced and solid by-product is avoided. As a result, the better mix and reactor effect of the high temperature gas phase phosgenation reaction are realized by using the reactor.
