| Abstract |
The paper describes an investigation of fresh and dealuminated Y and ZSM-5 type zeolites for their ability to physically adsorb at ambient temperature and also catalytically destroy chlorinated volatile organic compounds (CVOCs). The sorption of pure component CVOCs--trichloroethylene (TCE), methylene chloride (CH2C12) and carbon tetrachloride (CC14)--on chromium-exchanged ZSM-5 (Cr-ASM-5) was studied, and Lennard-Jones interactions of these molecules with the ZSM-5 framework were estimated to determine the types of site(s) occupied. The effects of water vapor and presribed CVOCs on TCE sorption capacities of Cr-ASM-5 are discussed. Also in the study, fresh Y and ASM-5 zeolites were subjected to silicon chloride (SiC14) dealumination in order to decrease the pickup of water on these zeolites. Simultaneously, the TCE pickup on the dealuminated zeolites increased significantly. |
