Based on the requirements of environmental protection and solving the issue of energy crisis, this thesis discusses the application of superacid catalyst in energy chemistry. The main method of this research is catalytic oxidation. The results of this resarch play an important role to utilization of energyThis paper was divided four partsThe first part is the introduction of superacid catalyst theory, including its development and application. Such as the definition of superacid, the application in the field of organic chemistry and the mechanism of inactive. At the same time, the related development of this field was also presented. What's important is the introduction of the meaning and innovation of this paper.The second part is adopted slurry reactor, superacid catalyst, and different oxidation, in order to analyse the efficient of desulfurization from thiophene The catalysts were characterized by FT-IR, SEM, XRD, XPS. The analysis of product is detected by GC-MS. The result is that in the O3 oxidation system, no sulfurates were found. It means that this method has the advantages of low reaction temperature, short reaction time and high efficient. Depending on the message of characterization, the possible mechanism was also discussed.The third part foused on the superacid function of coupling n-heptane under different condition. The characterization of catalyst was also processed by FT-IR, XPS, XRD.The last part pays attention to the research of more extensive short-chain alkanes system. It has been proved that short chain alkanes could couple under air existed, assisted by superacid catalysis. Different reactant and kind metal could raise the different distribution of pruducts. XPS also used to analyse the metal element on the surface of catalyst. Compared to the reported results, this research shows more extensive field. At last, based on the above experiments and rusults, the possible rules were also summarized.
