The invention provides a ruthenium complex dolomite solid base catalyst for biodiesel, a preparation method thereof and application thereof, and belongs to the technical field of catalyst preparation. The preparation method of the biodiesel ruthenium complex dolomite solid base catalyst comprises: S1, drying the dolomite powder and immersing in a cerium nitrate solution for ultrasonic immersion treatment; S2, taking the impregnated product after the step S1 is taken out and dried; Calcination activation is obtained. The ruthenium complex dolomite solid base catalyst of the invention mixes the rare earth metal lanthanum with dolomite by the impregnation method, and uses the widely used dolomite as a raw material to solve the problem of high raw material cost and waste of resources, and at the same time, the mechanical properties of the prepared solid base catalyst are prepared. Good, good stability, high catalytic transesterification efficiency and reusability, so it has good practical application prospects. |
