Abstract: Disclosed is a method and apparatus for removing oxygen from hydrogen, hydrocarbon, or halogenated hydrocarbon gas which contains about 0.01 to about 10 mole % oxygen. The oxygen removal is accomplished by contacting the gas with a Hopcalite catalyst at a temperature of about 100.degree. to about 300.degree. C. The invention can be part of a process for making 1,2-dichloroethane where, in a first reaction, ethane and chlorine are reacted to make ethylene and hydrogen chloride and, in a second reaction, the ethylene and hydrogen chloride are reacted with excess oxygen to make the 1,2-dichloroethane. The unreacted ethane can be recycled to the first step after the method of the invention is applied to remove the oxygen.

Abstract: A process for mixing hot ethane with chlorine gas using a mixer consisting of a main pipe through which ethane is conducted, and four or more jets through which chlorine gas is introduced into the main pipe. The angle between the axis of each jet and the line from the center point to the point where the axis of each jet makes contact with the inside surface of the main pipe ranges between about 30.degree. to 45.degree..
