Abstract：This paper summarizes the progress of dehydrogenation of light alkanes to light olefins, which includs the catalysts and technologies of anaerobic and aerobic dehydrogenation. The chemical looping technology, a method of dehydrogenate of light alkanes to light olefins is proposed. In the chemical looping technology, the oxygen carriers as mild oxidants were applied to the oxidative dehydrogenation of light carbon alkanes to light olefins, which could increase the light alkanes conversion rate of reaction. It is pointed out that the researches on the dehydrogenation of light alkanes to olefins mainly include two sections: The oxygen carrier should be focused on the followingthree aspects: multiple active oxygen carrier, coupled catalytic oxygen carrier oxygen carrier and weak oxidizing oxygen carrier;For the bottleneck of slow reaction between oxygen carrier and light alkane, the design idea of the reactor should be optimized.
