Abstract
Preparation of zinc oxide impregnated zeolite from natural zeolite and its catalytic activity in pentanol dehydration was investigated. The impregnation process was conducted by two main steps; chemical activation followed by wet impregnation using ZnSO4.7H2O as precursor and the characterization of prepared material was conducted by X-ray diffraction, scanning electron microscope (SEM-EDX) and surface acidity measured by pyridine adsorption-FTIR spectrophotometric method. As catalytic activity evaluation, pentanol dehydration over prepared material under vapor phase reaction mechanism was conducted by varied temperature of 300,400, 500 and 700oC. For mechanistic study, the product of reactions was analyzed by using gas chromatographymass spectrometry(GC-MS) . It is found that temperature affect strongly to the reaction mechanism in that at the temperature of above 500oC the etherification was occured. From the comparation with zeolite, it can be noticed that the role of solid acidity also influences the reaction mechanism.
