Abstract
The removal of fluoroalkanes from fluoroalkane-containing hydrocarbon streams, preferably C3 to C5 hydrocarbon streams. The fluoroalkane-containing hydrocarbon stream is contacted with an adsorbent containing a strong acid function, preferably a silica gel or a strong cation ion-exchange resin having sulfonic acid functionality
Claims16
A process for conditioning an adsorbent comprising:
- (a) providing an adsorbent having strong acid functionality for conditioning;
- (b) optionally, applying water to the adsorbent;
- (c) applying an alcohol to the adsorbent;
- and
- (d) drying the adsorbent at an elevated temperature.

A system for removing fluoroalkanes from a fluoroalkane-containing hydrocarbon stream comprising:
- (a) a fluoroalkane-containing hydrocarbon stream comprised of C2 to C10 hydrocarbons and from about 0.01 to about 3 wt. % C3 to C5 fluoroalkanes;
- and
- (b) an adsorbent having strong acid functionality in fluid communication with the fluoroalkane-containing hydrocarbon stream.
A system for conditioning an adsorbent comprising:
- (a) an adsorbent having strong acid functionality;
- (b) optionally a supply of water, capable of being introduced to the adsorbent to wash the adsorbent;
- and
- (c) a supply of an alcohol capable of being introduced to the adsorbent to wash the adsorbent.
