摘要
Abstract
A new amino-acid functionalized heteropoly tungstate ([Ala]3PW) was prepared with alanine and phosphotungstic acid as raw materials.The structure of [ Ala ] 3 PW was characterized by XRD, FT-IR.The removal of dibenzothiophene ( DBT ) in model oil was studied by using [ Ala ] 3 PW as catalysts, hydrogen peroxide as oxidant and imidazolium tetrafluoroborate ( [ HMIM ] BF4 ) as the extractant.The influence of reca it on temperature, the amount of catalysts, the molar ratio of O/S(H2O 2/DBT), the amount of extracat nt and types of thioph ene on the desulfurization efficiency were investgi ated.The results indicated that under the optimal reaction conditions of 10 mL model oil, 0.04 g of [Ala]3PW, O/S(mol ratio) =6, V([HMIM]BF4)/V(o il)=0.6, reaction temperature of 50 ℃na d reaction time of 180 min, removal of DBT was found tob e 98.2%.The catalyst could be recycled 4 times withotu a significant decreaes in activity.关键词
