摘要
Mordenite is a zeolite that has been used as a selective adsorbent and as a catalyst. Mordenite zeolite with crystal diameter 65 nm and crystal length 7 mu m was successively synthesized in the absence of organic template by hydrothermal method at 180 degrees C for 5 days after stirring at high speed and aging in the synthesis mixture with the molar composition of 12Na(2)O:100SiO(2):2Al(2)O(3):500H(2)O. The produced samples were investigated using XRD, SEM, FT-IR, EDS, DTA/TG and BET surface area. The prepared sample, crystallized in needle shape crystals. Total (BET) surface area was 52.14 m(2)/g whereas, total pore volume was 0.2 cm(3)/g. Average pore diameter was 24.16 angstrom. Thermogravimetry analysis (DTA/TG) showed that, at room temperature to 800 degrees C, mordenite mass loss is 6%. (C) 2011 The Society of Powder Technology Japan.
