Abstract

Abstract: Well-ordered trioctahedral saponites were successfully synthesized in strong basic system under high temperature, and were intercalated with Keggion ions. XRD, 27Al MAS-NMR, N2 adsorption and desorption , FTIR spectra of pyridine adsorption, TGA-DTA and TEM were used for the characterization of the synthetic aluminum-pillared saponites. The results illustrated that pillared saponites were highly-ordered and thermal stable above 800℃.Besides,after being pillared by aluminium oligmer,the Al-pillared synthetic saponite showed high conversion and hydroisomerization yield in the catalytic reaction of n-decane.

Key words: saponite, intercalated, pillared-saponite, n-decane, hydroisomerization
