简要介绍了生物质焦油的组成、分类以及危害，综述了白云石、橄榄石、凹凸棒石黏土以及其他钙基天然催化剂的研究进展，提出了提高催化剂活性的方法，包括选择适宜的煅烧温度、负载少量的镍铁等活性金属以及添加助剂等，为天然非均相催化剂在今后的研究提供参考依据。

The composition,classification and potential hazard of biomass tar are introduced briefly.The study progress concerning main natural catalysts such as dolomite,olivine,attapulgite clay and other calcium based natural catalysts is reviewed.The ways to improve the catalytic activity are put forward,such as selecting suitable calcination temperature,loading small amount of Ni or/and Fe active metals and adding metal promoters etc.It is expected to provide a basis for the exploitation of natural heterogeneous catalysts in the future.
