Aluminium-containing mesoporous molecular sieves (Al-MCM-41) with different
Al contents (Si/Al = 86.3, 43.9, 23.3, and 14.3) have been prepared using
cetyltrimethylammonium bromide as an organic surfactant and characterized b
y XRD, MAS NMR, and Nz sorption studies. Al-27 NMR studies reveal that the
Al is present in Td coordination in the samples. The samples were loaded wi
th Pt and used in the hydroisomerization of n-hexane. The reactions were ca
rried out at atmospheric pressure in the temperature range of 300-400 degre
es C. The optimum Pt content for the reaction was found to be around 0.3%.
High selectivities for isomerization were observed. (C) 1999 Academic Press
