Síntesis, Desarrollo y Optimización de un Catalizador para la Producción Verde de Biodiesel Que

Abstract

This work was conducted in two stages. In the first part was made the selection of a catalyst of seven catalysts considered friendly to the environment (ZnO, Al2O3, TiO2, ZrO2, V2O5, MoO3 and WO3) evaluating each in a test tube, heated in microwave oven. Besides evaluating the oxides were functionalized each with sulfates, phosphates and chlorides in search of an increase in conversion in the evaluation of microwave. All catalysts were characterized by FT-IR to assess whether the functionalization was effective and if there are changes in the structure of the catalyst. Once selected, the catalyst was carried out the second stage. The selected catalyst was studied and characterized to carry out the optimization by modifying its structure in order to increase its catalytic activity. The modifications to the structure of the catalyst were determined by physical characterization techniques such as SEM, XRD, BET area and FT-IR. In addition to physical characterizations were performed with the chemisorption of ammonia TPD technique to determine the acidity of the catalyst. Finally the kinetic study was made of the catalyst in test tubes heated by microwaves.
