Реферат: The eff ect of integration iron cations into zeolite ZSM-5 on the physicochemical properties of the material and the direction of transformation of n-dodecane and 2-methylthiophenes (5000 ppm S) in catalytic cracking was investigated. The integration of iron led to a signifi cant increase in the total acidity of zeolites with SiO2/Al2O3 ratios of 23 and a slight increase for zeolites with SiO2/Al2O3 ratios of 80. For both types, the volume of micropore remained unchanged. It was found that modifying zeolite ZSM-5 with SiO2/Al2O3 ratios of 23 with iron increased the yield of aromatic compounds from 27.1 to 38.1 wt %, and light olefi ns from 22.5 to 30.3%. The content of sulfur compounds decreases by 44% with an increase in the proportion of iron oxide in zeolite ZSM-5 with SiO2/Al2O3 ratios of 23.
