Transformación catalítica del aceite de palo santo sobre zeolita faujasita HY.

Abstract

Abstract:In the present work, the transformation of the essential oil of Palo Santo in liquid phase was studied, using as catalyst a commercial type Y zeolite. The zeolite was taken to the proton shape and characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD), specific area analysis (AE) and Total Acidity (TA) analysis. The reaction of the oil catalyzed by the HY zeolite was carried out in a system by loading in liquid phase, without the use of solvent, at atmospheric pressure and boiling under reflux. The analysis of the reaction products was performed by Gas Chromatography (GC) with a mass spectrometry detector. In the tests with catalyst, an increase in the conversion of the main components of the oil, limonene and phellandrene was observed, increasing the mass ratio catalyst / mass oil (Mc / Ma) and the reaction time. Low Mc / Ma ratios favored isomerization for lower conversions and as this ratio increased, greater conversion was obtained and a higher proportion of products called Others. The feasibility of recovering the used catalyst was checked.
