Abstract
A method for synthesizing and application embedded alkaline earth metal oxide solid alkali includes: firstly, synthesizing an alkaline earth metal organic skeleton with single or multiple alkaline earth metals (Mg, Ca and Sr) as central metal elements; and then controlling the heating process to carry out high-temperature pyrolysis in a non-oxidizing atmosphere, so that the alkaline earth metal oxide are embedded in the nano carbon sheet to obtain a solid alkali catalyst. Finally, the catalyst is used to catalyze the transesterification of palm oil and methanol to produce biodiesel. The active site of the solid alkali obtained by the method is anchored on the nano-like carbon sheet, so that the active site is directly exposed on the surface of the catalyst, the catalytic activity is improved, the loss of the active site is inhibited, and the stability of the solid alkali catalyst is enhanced.
