| Abstract: | In water steam,molecular sieves Si MCM 41 and Al Si MCM 41 have beensynthesized from amorphous gels containing cetyltrimethylammonium bromite(CTAB) Their crystalline conditions have been studied The molecular sieve Al Si MCM 41 wasalso prepared using small amount of surfant CTAB(CTAB/Si=0 025) From N 2adsorption isotherms,porous structure parameters,such as surface area,pore volume and pore distribution,have been calculated The surface areas are 1026 m 2 g -1 (Si MCM 41)and 1081 m 2 g -1 (Al Si MCM 41) The average pore diameters are 3 39 nm(Si MCM 41)and 2 62 nm(Al Si MCM 41) |
