dc.description.abstractTHIS PAPER PROPOSES THE CHILEAN NATURAL ZEOLITE AS CATALYST ON BIO-OIL UPGRADE PROCESSES. THE AIM OF THIS STUDY WAS TO ANALYZE CHEMICAL COMPOSITION OF BIO-OIL SAMPLES OBTAINED FROM CATALYTIC PYROLYSIS OF CHILEAN NATIVE OAK IN ORDER TO INCREASE BIO-OIL STABILITY DURING STORAGE. IN ORDER TO IDENTIFY CHEMICAL COMPOUNDS BEFORE AND AFTER STORAGE, BIOMASS PYROLYSIS WAS CARRIED OUT IN A FIXED BED REACTOR AT 623 K AND BIO-OIL SAMPLES WERE CHARACTERIZED BY GAS CHROMATOGRAPHY/MASS SPECTROPHOTOMETRY (GC/MS). A BIO-OIL FRACTIONATION METHOD WAS SUCCESSFULLY APPLIED HERE. RESULTS INDICATE THAT BIO-OIL VISCOSITY DECREASES DUE TO ACTIVE SITES ON THE ZEOLITE FRAMEWORK. ACTIVE ACIDS SITES WERE ASSOCIATED WITH AN INCREMENT OF ALCOHOLS, ALDEHYDES, AND HYDROCARBON CONTENT DURING STORAGE. HIGHER COMPOSITION ON ALDEHYDES AND ALCOHOLS AFTER STORAGE COULD BE ATTRIBUTED TO THE OCCURRENCE OF CARBONYL REDUCTION REACTIONS THAT PROMOTES THEM. THESE REACTIONS ARE INFLUENCED BY ZEOLITE SURFACE CHARACTERISTICS AND COULD BE ACHIEVED VIA THE DIRECT CONTRIBUTION OF BRØNSTED ACID SITES TO CHILEAN NATURAL ZEOLITE.
