合成气制低碳烯烃催化剂研究进展
摘要：摘要低碳烯烃是现代化学工业的基石,其核心产品是合成纤维、塑料、橡胶等高分子材料极为重要的中间体,低碳烯烃的产量是衡量一个国家石油化工行业发展水平的重要标志。对合成气制低碳烯烃的主要工艺路线进行综述,归纳合成气经费托合成及双功能催化体系制备低碳烯烃的主要反应机理,详细讨论了不同工艺路线的催化剂的研究进展,并总结合成气一步法制备低碳烯烃产物影响因素,解析了不同催化剂的失活机理,最后对未来高效催化剂的发展方向进行展望。合成气制低碳烯烃催化剂的高速发展,可为我国双碳目标约束条件下由生物质经非石化路线制备低碳烯烃提供理论支撑。
Abstract:：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.
