摘要:

综述了双金属催化剂在生物质焦油及其模型化合物催化蒸汽重整领域的研究现状,梳理了常用双金属催化剂的类型及不同催化剂催化焦油重整的性能,总结了影响双金属催化剂性能的主要因素,探讨了焦油催化重整的反应机理,并阐释了催化剂失活-再生反应机制。文中指出:双金属催化剂丰富的活性位点和双金属之间的协同作用促进了催化剂性能的提升,双金属活性相和载体之间适宜的相互作用增强了催化剂的稳定性;双金属催化剂在焦油蒸汽重整方面具有潜在的应用前景。目前双金属催化剂的活性、稳定性仍然无法满足焦油催化重整的产业化应用需求。下一步需开发催化剂的精准调控技术,深入阐释其催化反应机理,为焦油催化蒸汽重整产业化发展提供技术指导。

Abstract:

This review assessed the status of bimetallic catalysts in catalytic steam reforming of biomass tar and related model compounds. The types of common bimetallic catalysts and their performance in catalytic reforming of biomass tar were investigated; the factors affecting bimetallic catalyst performance were summarized; the reaction mechanism of catalytic tar reforming was outlined; and the catalyst deactivation and regeneration reaction mechanisms were clarified. The rich active sites and the synergistic interaction between bimetal catalysts promote the improvement of catalyst performance, and the appropriate interaction between bimetal active phase and support enhances the stability of the catalyst. Bimetallic catalysts have potential applications in the steam reforming of tar. At present, the activity and stability of bimetallic catalysts still cannot meet the needs of industrial applications of tar catalytic reforming. In the next step, it is necessary to develop the precise regulation technology of the catalyst and deeply explain its catalytic reaction mechanism, so as to provide technical guidance for the industrial development of tar catalytic steam reforming.

Key words: biomass tar, catalytic reforming, steam reforming, bimetallic catalyst, regeneration
