Abstract:
A facile one-pot synthesis method was developed to produce a new hybrid heterogeneous catalyst for catalytic oxidation removal of sulfur-containing compounds from petroleum samples. The presented catalyst is a Cd substituted heteropoly phosphomolybdic acid (HPMo) based on ionic liquid, which is stabilized on mesoporous silica. The physicochemical investigation of the catalyst was studied using FTIR, SEM, BET, XRD, and TEM. The results of XRD and FTIR proved that manganese was included in the catalyst structure, and the catalyst kept its Keggin type structure. The percentage of sulfur compounds removed after performing the catalyst activity in different conditions including temperature, catalyst amount, reaction time, and oxidant ratio was measured by GC-FID. Using the presented catalyst, it is possible to perform green desulfurization in a very short time with low cost and high removal efficiency. The performance of the synthesized catalyst in optimal conditions on 4 types of real fuels was evaluated.
