Abstract: (1491 Views)
Research subject: Propylene is one of the most prominent gases due to some valuable products and derivatives such as polymers, solvents, dyes, etc., which makes it one of the most important building blocks in the chemical industry. Due to the limitations of steam cracking and fluid catalytic cracking processes in terms of low selectivity, energy consumption, and significant CO2 emission, these processes cannot fulfill the growing demand for propylene. In recent decades, the dehydrogenation of light alkanes to produce light olefins, especially propane dehydrogenation (PDH), has attracted much attention. Pt-Sn and CrOx catalysts, which are widely used in this process, have good dehydrogenation activity and selectivity; However, the limitations of price, deactivation, and environmental problems are serious and have led researchers to improve coking stability, sintering Pt catalysts, and find new and environmentally friendly catalysts.
Research approach: : One of the challenging issues in the PDH process is achieving
appropriate catalyst. Several solutions, including modification of the base and introduction of additives, have been proposed to enhance the catalytic performance overcome the problems, and increase the resistant stability of Pt, Cr catalysts. Understanding the structure-performance relationship of catalysts during the PDH reaction is essential to achieve innovation in new high-performance catalysts. This research aims to introduce the characteristics of the dehydrogenation reaction, the progress made in the development of the catalyst, and the existing challenges. This research provides a deep understanding of the reaction mechanism and its role in the development and future directions of the catalyst for practical and industrial development.
Main results: This study offers a detailed understanding of how the reaction mechanism works and its significance in the development and future directions of the catalyst for practical and industrial advancement.
