  • Selective removal of perfluoroisobutylene from streams of halogenated hydrocarbons
    Patent number: 5705719
    Abstract: An adsorption-desorption process using activated carbon removes perfluoroisobutylene from gaseous streams of halogenated hydrocarbons. Choice of gas and temperature profile used for desorption of adsorbed compounds and regeneration of the activated carbon facilitates concentration and removal of the perfluoroisobutylene.
