Abstract
A fixed-bed adsorption experiment was carried out to remove and to recover 2,2,3,3,3-pentafluoropropanol, developed as a substitute for CFC-113, by use of high silica zeolite (HSZ) pellets. For four kinds of HSZs, adsorption equilibria can be correlated to Langmuir equation. The mass transfer was studied in detail for a Y-type zeolite which showed the largest amount adsorbed. Intraparticle diffusion was found to be controlled by macropore diffusion. Further, the regeneration of HSZ was studied under reduced pressure with heating for industrial use. The regeneration of HSZ was completed within a shorter time at higher temperatures. The degradation of HSZ was not observed.
