Research Progress on Propylene Preparation by Propane Dehydrogenation

Abstract

At present, the production of propylene falls short of the demand, and, as the global economy grows, the demand for propylene is anticipated to increase even further. As such, there is an urgent requirement to identify a novel method for producing propylene that is both practical and reliable. The primary approaches for preparing propylene are anaerobic and oxidative dehydrogenation, both of which present issues that are challenging to overcome. In contrast, chemical looping oxidative dehydrogenation circumvents the limitations of the aforementioned methods, and the performance of the oxygen carrier cycle in this method is superior and meets the criteria for industrialization. Consequently, there is considerable potential for the development of propylene production by means of chemical looping oxidative dehydrogenation. This paper provides a review of the catalysts and oxygen carriers employed in anaerobic dehydrogenation, oxidative dehydrogenation, and chemical looping oxidative dehydrogenation. Additionally, it outlines current directions and future opportunities for the advancement of oxygen carriers.

Recent progress in the development of catalysts for propane dehydrogenation in the presence of CO2

“…8,9 This ever-increasing demand for propene has resulted in a gradually widening gap between propene supply and demand. 10–12 This trend indicates that the propene industry will face greater challenges and development opportunities in the future (Fig. 1).…”

Copper-Promoted Platinum Supported on HSSZ-13 Zeolite Catalysts for Propane Dehydrogenation to Propylene

“…Synthetic plastics, rubber, and fiber are the three major synthetic materials; their important raw material is propylene. , In addition, polypropylene protective equipment played an important role during the coronavirus disease . With the emergence of shale gas, propane dehydrogenation (PDH) has emerged as a significant alternative technique for producing propylene, as the conventional methods of producing the chemicalfluid catalytic cracking of heavy oil and steam cracking of naphthahave increasingly become insufficient to fulfill the growing demand. − Cr-based and Pt-based catalysts are the main catalysts for PDH.…”

Advancements of MOFs in the Field of Propane Oxidative Dehydrogenation for Propylene Production

“…Propylene, as one of the most prominent industrial raw materials, holds significance in terms of demand, second only to ethylene. The global propylene market is estimated to reach 117.5 million metric tons in 2022 and is projected to reach a revised volume of 155.2 million metric tons by 2030, exhibiting a compound annual growth rate of 3.5% during the analysis period from 2022 to 2030 [ 1 ]. DHP is a significant method for the production of C 3 H 6 in industry.…”
