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.
Claims18
A process for removing perfluoroisobutylene from a gaseous stream of halogenated compounds, comprising contacting the stream with dry activated carbon for a time sufficient to achieve effective removal of PFIB, whereby said perfluoroisobutylene is adsorbed by said activated carbon.
A process for converting perfluoroisobutylene to CF.sub.3 CH.sub.2 CF.sub.3, comprising contacting said perfluoroisobutylene with superheated steam in the presence of activated carbon and forming said CF.sub.3 CH.sub.2 CF.sub.3 as a result thereof.
