制备方法对InZr复合氧化物/SAPO-34催化剂CO2加氢制备低碳烯烃性能的影响

Effects of preparation methods on the performance of InZr/SAPO-34 composite catalysts for CO2 hydrogenation to light olefins

    摘要
  • 摘要: 低碳烯烃是重要的化工原料，乙烯更是作为衡量一个国家石油化工发展水平的重要标志，使用CO2催化加氢制备低碳烯烃是实现CO2高值化利用的重要途径。在众多催化剂中，InZr复合氧化物/SAPO-34催化剂因其高低碳烯烃选择性和高稳定性展现出潜在的研究和应用前景。本工作研究了不同制备方法对InZr复合氧化物/SAPO-34催化剂CO2加氢制备低碳烯烃的影响，结果表明，共沉淀法制备的催化剂具有最高的催化活性，溶胶凝胶-沉积法制备的催化剂具有最高的低碳烯烃选择性，并结合多种表征手段揭示了InZr复合氧化物/SAPO-34催化剂内在构效关系。

     

    Abstract: Light olefins are of great importance as chemical raw materials, and ethylene is a crucial symbol to evaluate the development level of petrochemical industry. Catalytic hydrogenation of CO2 to light olefins is one of the most vital approaches to utilize CO2 with high added valued. InZr/SAPO-34 composite catalyst shows prominent potential in research and application because of their high light olefins selectivity and high stability in CO2 hydrogenation. In this study, the effects of different preparation methods of InZr/SAPO-34 composite catalyst for CO2 hydrogenation to light olefins were studied in depth. The catalyst prepared by co-precipitation method showed the highest catalytic activity, and the catalyst prepared by sol-gel-precipitation method showed the highest light olefins selectivity. The structure-activity relationship of InZr/SAPO-34 catalysts were revealed by various characterization methods.
