Název v původním jazyce

Influence of ageing and duration of crystallization on morphology of silicalite-1 crystal layers

Popis výsledku v původním jazyce

Crystal morphology, arrangement of the silicalite-1 crystals in a separating layer of composite membrane and membrane integrity were studied in dependence on synthesis conditions. The characteristics of the silicalite-1 crystals (crystallinity, purity, size) and separating layer (thickness) were observed by X-ray diffraction and scanning electron microscopy. The silicalite-1 crystal layers were synthesised on the asymmetric &#61537;-alumina supports prepared in our laboratory. The synthesis mixture usedfor preparation of the ceramic silicalite-1 composite membranes contained Aerosil 380 (Degussa) as a source of silica. The composition of the synthesis mixture was 12g of Aerosil 380 dissolved in 100 ml of TPAOH with a molar ratio of 100 SiO2: 42.9 TPAOH: 2229 H2O. The synthesis process was modified by variation of ageing and crystallization time. The ageing time was varied between 3 and 35 days and duration of crystallization between 24 and 96 hours to control size of silicalite-1 crys
