在合成不同钒掺量磷钼杂多酸基础上,用降解法合成了3种Keggin结构的镧钼钒磷杂多配合物,并以之为催化剂,分别用双氧水、过氧乙酸作氧化剂,甲醇、乙二胺作为萃取剂进行了柴油氧化脱硫实验.实验结果表明:以掺有2个钒原子的镧钼钒磷杂多配合物为催化剂、过氧乙酸为氧化剂、乙二胺为萃取剂可将市售柴油的硫含量由1 815.8μg.g-1降低至102.6μg.g-1,脱硫率达到了94.35%. Based on the synthesis of heteropolyphosphorolybdophosphotungstic acid, three kinds of heteropolyacid complexes with Keggin structure were synthesized by the degradation method. Using these as catalysts, hydrogen peroxide and peracetic acid were used as oxidants, methanol , Ethylenediamine as an extractant for diesel oxidation desulfurization experiments.The experimental results show that: with two vanadium atoms lanthanum molybdovanadophosphoric heteropoly complexes as catalyst, peracetic acid as oxidant, ethylenediamine as extractant The sulfur content of commercial diesel oil was reduced from 1 815.8μg.g-1 to 102.6μg.g-1, the desulfurization rate reached 94.35%.
