Research Progress and Perspective in Technology of Ethane Dehydrogenation to Ethylene
In the context of carbon neutrality and global energy supply and demand adjustments,the lightweight of ethylene production feedstock has become the mainstream trend.Technology of ethane dehydrogenation to ethylene has some advantages,such as low energy consumption,low carbon emissions,short process as well as high yield and low cost.However,currently,ethylene is mainly produced through ethane steam cracking in industry,while other methods are relatively immature.This review focuses on the research progress of technologies and catalysts for ethane dehydrogenation to ethylene in recent years,including direct catalytic dehydrogenation,O2 assisted oxidative dehydrogenation,CO2 assisted oxidative dehydrogenation,chemical looping oxidative dehydrogenation,catalytic membrane reactor dehydrogenation,and other emerging processes and catalysts.The challenge lies in developing more effective catalysts and lower energy consumption technologies,as well as designing appropriate conversion path of the H2 product to breakthrough the thermodynamic constraints.Catalytic membrane reactor dehydrogenation and chemical looping oxidation dehydrogenation technologies have very broad market and industrial development prospects.
