다국어 초록 (Multilingual Abstract)
Hydrogen mordenite[HM(10)], aluminum-deficient mordenite (HM(22)] (SiO₂/A1₂O₃=22), and their steam-treated mordenites [HM(10)_(s,HCl), whichis washed with hydrogen chloride solution after steam-treating, and HM(22)_s]were prepared and characterized by measuring nitrogen adsorption capacities, XRD analysis, NMR studies, and IR studies on ammonia adsorption and hydroxyl bands. Catalytic reaction of n-hexane with hydrogen was carried out on these samples. HM(10) and HM(22) revealed fast deactivation rate, but elimination of IR 3600㎝^(-1) band from these samples by steam-treating reduced the deactivation rate. The quantity of ammonia adsorption was reduced by steam-treating and acid-leaching, but the quantity showed no correlation with the activity of the n-hexane conversion. Isomerization selectivity was much improved by steam-treating. HM(22)_s and HM(10)_(s,HCl)showed high selectivity for 3-methyl pentane and > C_6, respectively.
