In recent years, one of the most important environmental researchers' subjects has been introduced appropriate and effective methods for desulfurization from fossil fuels and prevent the release of sulfur compounds obtained from combustion into the environment. In this study, sulfur oxidation of refractory organosulfur compounds supported on graphitic carbon nitride (g-C3N4) was examined ‎utilizing‎ a novel catalyst comprising monolacunary phosphomolybdate (PMo11). The optimized reaction ‎conditions, which encompass the loading amount of PMo11 on g-C3N4, the dosage of catalyst, reaction time, ‎reaction temperature, the proportion of O/S, initial DBT ‎concentration, and type of model fuel, have been explored. This catalytic system's superiority has been shown by obtaining 98.6% conversion of DBT in the model fuel and 93.7% sulfur ‎removal from real fuel.

单孔磷酸钼钼酸盐负载在介孔石墨氮化碳上:一种对模型和真实燃料进行氧化脱硫的环保型高效催化剂

近年来,最重要的环境研究人员之一被引入了适当有效的方法,用于从化石燃料中脱硫,并防止燃烧获得的硫化合物释放到环境中。在这项研究中,研究了利用一种新型的包含单钼磷钼酸盐(PMo 11)的催化剂对石墨化碳氮化物(gC 3 N 4)上负载的难熔有机硫化合物的硫氧化。优化的反应条件,其中包括PMo 11在gC 3 N 4上的负载量研究了催化剂的用量,反应时间,反应温度,O / S的比例,初始DBT浓度和模型燃料的类型。通过在模型燃料中获得98.6%的DBT转化率和从真实燃料中去除93.7%的硫,可以显示出该催化系统的优越性。
