    NaX zeolite is used to collect and decompose chlorofluorocarbons (CFCs) and to determine the behavior of CFC-11 molecules in zeolitic pores using various methods. At room temperature, CFC-11 molecules are adsorbed on the micropores of NaX zeolite, and at 400°C CFC-11 molecules were decomposed by the catalytic reaction of NaX zeolite. Approximately 30 CFC-11 molecules are adsorbed and 90 CFC-11 molecules are decomposed per unit cell of NaX zeolite. HCl and HF gases are detected in the outlet gas of the decomposed CFC-11. The results indicate that Al-O bonds in the zeolite crystal structure are destroyed. The destruction of the zeolite crystal structure tends to occur on the selective planes along the hhh, hh0 and 3hhh directions.
