低温等离子体协同Ni基催化剂重整焦油研究进展

Non-thermal plasma-catalytic reforming of tar over Ni-based catalysts

  • 摘要: 生物质气化制合成气(H2/CO)过程中伴随副产物焦油的产生,会引发环境污染问题和阻碍气化技术发展。低温等离子体与镍基催化剂结合能够利用等离子体的低温反应及催化剂的高选择性优势,将焦油定向重整转化为合成气。但镍颗粒在重整过程中会形成积炭沉积易导致催化剂失活,所以设计和改性催化剂提高其抗积炭性能成为解决催化剂失活问题的关键。本工作综述了近年来低温等离子体催化重整焦油体系内镍基催化剂失活原理以及催化剂的设计和改性以提高其抗积炭性能、低温等离子体重整焦油反应器类型及其机理、低温等离子体与催化剂的协同作用等方面的研究进展,并对协同体系重整焦油未来发展方向进行展望。本综述为低温等离子体催化重整焦油体系内镍基催化剂的设计与开发提供了参考依据。

     

    Abstract: In the process of biomass gasification to produce syngas (H2/CO), the production of tar as a by-product causes environmental pollution and hinders the development of gasification technology. The combination of non-thermal plasma and nickel-based catalysts can take advantage of the low reaction temperature of plasma and the high selectivity of catalyst to transform tar into syngas. However, carbon deposition of nickel particles in the reforming process easily causes catalyst deactivation, so designing and modifying the catalyst to improve its carbon resistance is the key to solving the catalyst deactivation problem. In this paper, the deactivation mechanism of nickel-based catalysts in the non-thermal plasma-catalytic reforming of tar system, the design and modification of catalysts to improve their carbon resistance, the types of the non-thermal plasma reactor and its tar reforming mechanism, the synergistic effects of non-thermal plasma and catalysts are reviewed. The research prospect of non-thermal plasma-catalytic reforming of tar system is also discussed. This paper provides a reference for the design and development of nickel-based catalysts in the non-thermal plasma-catalytic reforming of tar system.
