催化重整生物质焦油的Ni基催化剂中常见助剂和载体的研究进展

Research Progress of Common Co-catalysts and Supports of Ni Based Catalysts for Catalytic Reforming of Biomass Tar

Ni基催化剂作为催化重整生物质焦油过程中一种高效的催化剂,仍然存在易烧结、易积炭等问题,使得其活性和稳定性难以得到保证。通过添加合适的助催化剂和使用催化剂载体可有效缓解Ni基催化剂的烧结与积炭问题。介绍了稀土元素Ce、磁性元素Fe和Co、碱土金属Ca和Mg作为助催化剂,以及天然矿物材料白云石和橄榄石、天然加工材料煅烧贝壳和稻壳炭、合成材料β-Al_2O_3和SBA-15作为载体的Ni基催化剂的研究进展,并展望了今后的研究方向。

Ni as an ideal catalyst applied in catalytic reforming of biomass tar has some problems such as easy sintering and coke deposition,which makes it difficult to guarantee the activity and stability. Research shows that the sintering and coke deposition of Ni-based catalyst can be effectively alleviated by adding appropriate co-catalyst and using catalyst supporter. This paper introduces research progress of rare earth elements Ce, magnetic elements Fe and Co, alkaline earth elements Ca and Mg as co-catalysts, as well as natural mineral materials dolomite and olivine, natural processed materials calcined shells and rice husks, synthetic materials β-Al2O3 and SBA-15 as the carrier of Ni-based catalyst, and the prospects for future research.
