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.
