The Study on the Transesterification Catalyzed by Sodium Compound Loaded on Carbide Slag

NaOH, Na2CO3 and NaNO3 loaded on carbide slag are used as transesterification catalysts in a batch-type transesterification system. The activated catalysts are characterized by X-ray diffraction and the corresponding catalytic efficiencies are compared. NaOH loaded on calcined carbide slag gains the highest catalytic efficiencies. The optimal activated temperature of NaOH loaded on calcined carbide slag is obtained.
