A New Method for the Synthesis of Cr-V@MOF5 Catalyst Regarding the Investigation of the Simultaneous Effect of Effective Parameters in the Oxidative Dehydrogenation of Propane

This research study utilized the synthesis method of the Cr-V@MOF5 catalyst to integrate findings from multiple prior studies. The oxidative dehydrogenation method was chosen due to its exothermic nature and lack of thermodynamic constraints on catalytic conversion, which are advantages over catalytic dehydrogenation without oxidation and thermal breakdown. In this research at Islamic Azad University in Omidiyeh, the catalytic bases of zeolite and metal-organic framework (MOF) were used. The synthesized catalysts were modified by some improvers, and each improver was assessed to find out which one is suitable for this oxidative dehydrogenation process. The goal was to reach the optimal point of propane-to-propylene conversion using statistical analysis. Design Expert software was utilized to ascertain the difference between the laboratory data and the optimized objective function. Subsequently, a comparison was made regarding the quantity of propylene produced in the presence of two distinct catalysts. The results revealed that the presented synthesis method is not repeatable. Also, the results showed that since the organometallic framework catalyst had a larger surface area compared with the ZSM-48 zeolite, it had a better catalytic performance than the zeolite catalyst. The functional comparison of zeolites and organometallic frameworks in terms of structure and the results of propylene production resulting from the performance of these two catalysts is also among the achievements of the project.
