Abstract

Abstract:

Solid base is considered to be an excellent catalyst for the preparation of renewable energy biodiesel by transesterification. In this paper, a comprehensive experiment is designed on the basis of scientific research results. KF/La₂O₂CO₃ solid base catalyst was prepared by impregnation method, and its phase and surface basicity were measured by X-ray diffraction and temperature programmed desorption with CO₂, respectively. In addition, the catalytic activity of KF/La₂O₂CO₃ was tested by using the transesterification of tributyrin and methanol as a model reaction.
