Preparation of basic mesoporous molecular sieves K_2O/Mg-MCM-41 and its catalytic performance on the cracking of soybean oils

摘要

Mesoporous molecular sieves Mg-MCM-41 are prepared in hydrothermal system and characterized by XRD and TEM. By impregnating Mg-MCM-41 with KNO_3 solvent, basic K_2O/Mg-MCM-41 is prepared. K_2O/Mg-MCM-41 is used as catalysts on the cracking of soybean oils, and the cracking products are of the similar acid value as those from Na_2CO_3 or K_2CO_3 as catalysts. The performance of cracking oil and the influence of the amount of K_2O on catalytic performance are in detail examined.
