Catalytic Conversion of Hydrocarbons over Nanoscale Zeolitic Catalysts Based on Cerium-Modified HZSM and MCM-41

The study of HZSM-5 and MCM-41 zeolite nanocatalysts is of great importance in the field of petrochemistry.Nanocatalysts are used to increase the efficiency of chemical reactions, improve product selectivity, and reduce energy consumption.Zeolite-based catalysts are in high demand due to their excellent selectivity and catalytic activity.Currently, the catalytic cracking of tetradecane (C14H30) and pentadecane (C15H32) on zeolite-containing nanostructured catalysts is a significant area of research in the chemical industry.These catalysts possess microporous structures, which provide a large surface area and enhance the diffusion of reactant molecules, thereby increasing overall process efficiency.Studying catalysts and cracking processes contributes to increasing the yield of valuable products, improving the efficiency of petroleum refining, and reducing production costs.Various physicochemical methods were used to characterize the activity, structure, and properties of the studied catalyst.These methods include temperature-programmed desorption of ammonia (NH3-TPD), BET surface area analysis, scanning electron microscopy (SEM), chromatographic analysis, atomic absorption spectroscopy (AAS), and Xray diffraction (XRD).The study of HZSM-5 and MCM-41 zeolite nanocatalysts can enhance the selectivity toward olefins and iso-alkanes, promote dehydrogenation processes, influence the acidic properties of the catalyst, and provide a unique porous structure.
