摘要：
The production capacity of light olefins can reflect the technology level of the chemical industry. With the growing market demand for light olefins, novel and efficient light olefin production processes have attracted extensive attention. With chemical-looping light alkane oxidative dehydrogenation technology, through the reaction of lattice oxygen in the oxygen carrier and reactant molecules, the selective conversion of alkane molecules to olefin molecules can be realized, which can increase the yield of olefins and effectively reduce the process energy consumption and CO2 emission. This review analyzes the current research progress on the screening and theoretical design of oxygen carrier materials, the regulation mechanism of surface active sites and lattice oxygen transport in the bulk phase, and the optimization of reactors and processes for chemical-looping light alkane oxidative dehydrogenation technology. The future development trends of chemical-looping light alkane oxidative dehydrogenation technologies are systematically summarized to provide instructive perspectives for the advance of relevant technologies. © 2023 Chemical Industry Press.
