Development of zeolites for zeoforming reaction of naphtha

Abstract

High octane naphtha production is the primary purpose of the zeoforming process that genuinely needed in our modern life. Sulfur-containing compounds in gasoline are causing environmental pollution and catalysts deactivation. The metal function supplied by non-noble promoters such as Fe, Mn, Ni, Co, Cu, and Zn deposited on the ZSM-5 type of zeolite. ZSM-5 zeolites prepared by successive hydrothermal treatment following by impregnation of promoters on ZSM-5 type zeolite. The catalysts were characterized, utilizing XRD, N₂ physisorption, FESEM, TEM, TPR-H₂, and TPD-NH₃. Bibliometric results show that feed conversion concerns are the primary focus in naphtha and zeolite topic studies. Particular attention has been paid to ZSM-5 and performance that may be crucial for improving the naphtha reforming reaction. The experimental results verified that different promoters' use has a profound effect on zeolites' physicochemical properties. It found that Fe interacts strongly with the ZSM-5 zeolite producing growth in the metal function activity. The zeoforming results indicate that the highest research octane number (RON) belonged to the Fe promoter. A Fe promoter's existence increased the stability and selectivity for C7+ isomers and aromatics, thus reducing the formation of sulphur and low-value products like methane and gases.
