Research Progress of Catalysts for Syngas to Light Olefins
Light olefins are the cornerstone of the modern chemical industry,the core products of which are the important intermediates for the preparation of fibers,plastics,rubber and other polymer materials.The production of low-carbon olefins is an important indicator to measure the development level of a country's petrochemical industry.In this work,the main process routes of syngas to produce light olefins were reviewed.The main reaction mechanisms of producing light olefins from syngas via Fischer-Tropsch synthesis and bifunctional catalytic system were summarized.The research progress of catalysts in different process routes was discussed in detail.The influencing factors of low olefin products from syngas by one-step method were summarized,and the deactivation mechanisms of different catalysts were analyzed.Finally,the development direction of high-efficiency catalysts in the future was prospected.The rapid development of catalysts for the synthesis of light olefins from syngas can provide theoretical support for the preparation of light olefins from biomass via non-petrochemical routes under the constraint of the"carbon peaking and carbon neutrality"goal in China.
