Abstract
Hydrothermal surfactant treatment was used to transform K10 montmorillonite (M), which is one of the acid activated clays used as a catalyst and/or ad sorbent, into a surfactant-treated K10 montmorillonite (SM). The material w as characterized by X-ray diffraction, isopropanol probe reaction, N-2 adso rption-desorption, pyridine-adsorption-FTIR, and TPR-MS. All the results sh ow that SM is a new type of mesoporous material having high surface area (4 08 m(2)/g), high thermal stability, and high catalytic activity for isoprop anol conversion.
