摘要
A study was conducted to evaluate the possibility of enhancing the biodiesel conversions in homogeneous reactors using ethanol by removing water through adsorption in zeolite 3A involving the catalyst formation and the transesterification steps. Commercial zeolite 3A in pelletized form was used in the investigations, while water picnometry was used to determine the solid density, which was determined from the average particle's mass and the solid density. A parameter was defined as the ratio between the mass of absorbent to the total mass in the system to evaluate the effect of the relative amount of absorbent used in the investigations. The removal of water by adsorption in the catalyst formation and its removal in the transesterification reaction were investigated. The observations were also confirmed by the evaluation of the conversion values of the transesterification reaction of castor oil in all the investigations conducted under the study.
