Abstract—The Natural zeolite catalyst (Si/Al = 2.5) was prepared by calsination. The physico-chemical properties were investigated by XRD, 29Si MAS NMR, SEM, GC-MS and FT-IR spectroscopy of pyridine adsorbed. The activity of test of these catalysts has been carried out over the liquid-phase conversion of α-pinene. The converson reaction with natural zeolite, the highest selectivity of terpin compound was 59.08% with a conversion of 99.78% at 120 min.
Index Terms—Natural zeolite, α–Pinene, conversion.
