Abstract

Aluminium-containing mesoporous molecular sieves (Al-MCM- 41) with different Al contents (Si/AlD86.3, 43.9, 23.3, and 14.3)have been prepared using cetyltrimethylammonium bromide as an organic surfactant and characterized by XRD, MAS NMR, and N2 sorption studies. 27Al NMR studies reveal that the Al is presentin Td coordination in the samples. The samples were loaded withPt and used in the hydroisomerization of n-hexane. The reactionswere carried out at atmospheric pressure in the temperature range of 300–400±C. The optimum Pt content for the reaction was found to be around 0.3%. High selectivities for isomerization were observed.
