Process for removing ethylene and vinyl chloride from gas stream |
摘要 |
A process for removing ethylene and vinyl chloride from a gas stream containing them by passing a mixed gas containing ethylene, vinyl chloride and a necessary amount of chlorine through a fixed-bed reactor charged with as a catalyst an activated alumina supporting at least 4% by weight of ferric chloride in terms of iron, said catalyst having an outer surface area per unit packed catalyst volume of not less than 7.8 cm.2/ml. Ethylene and vinyl chloride are converted into and removed as 1,2-dichloroethane and 1,1,2-trichloroethane. The concentrations of ethylene and vinyl chloride can be decreased to not more than 10 p.p.m. and not more than 20 p.p.m., respectively.
