Abstract
A process is provided for the removal of tertiary butyl chloride from a hydrocarbon stream, wherein the hydrocarbon stream is contacted at a temperature of from about 130.degree. to about 170.degree. C. with a particulate calcium oxide containing from 1 to 10 mole % of a Group 3 or 4 compound and the hydrocarbon stream is recovered containing a reduced level of tertiary butyl chloride.
Claims9
A process for the removal of bromine or chlorine from brominated or chlorinated hydrocarbons contained in an unsaturated mono- or di-olefinic hydrocarbon stream by contacting said hydrocarbon stream with particulate calcium oxide containing not less than 1 and not more than 10 mole %, based on the calcium oxide, of a compound selected from aluminum, cerium, silicon, aluminum-silicon, titanium and zirconium compounds maintained at a temperature of from about 130.degree. to about 170.degree. C. and recovering said hydrocarbon stream containing a reduced level of brominated or chlorinated hydrocarbons.
