Abstract: 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.

Key words: biomass tar, N-based catalysts, co-catalysts, supporters
