In this study, hollow microspheres based on fly ash from the Ekibastuz coal field (Kazakhstan) and natural zeolite from the Taizhuzgen field (Kazakhstan) were used for the synthesis of catalysts. The catalysts were tested in the process of sulfur dioxide oxidation with different SO2 content in the SO2-Ar gas mixture at a flow vortex plant of the “Emulsifier” type with a capacity of 2 m3 / h. Technology for the oxidation of SO2 with oxygen in an aqueous solution has been developed and the best technological parameters for the selective oxidation of SO2 with the production of sulfuric acid as a product have been determined. The degree of SO2 sorption is reached up to 95%. Also, the prepared catalysts were tested in the process of redox-catalytic cracking of fuel oil (with preliminary electromagnetic excitation of hydrocarbon molecules) to obtain light carbon fractions. The fuel oil of the Amangeldy Gas Processing Plant (AGPP, Kazakhstan) of the M-100 brand was studied as a feedstock. On the optimal catalyst in the products of oxidative cracking of fuel oil, the fraction of light gas oil makes up the main part. The resulting light gas oil contains a significant amount of alpha-olefins, which are scarce raw materials for the production of synthetic additives and oils.
