Biomass is considered to have potential to be used as an alternative energy source. Bio?oil (or biomass pyrolysis oil) is a green product ob? tained from lignocellulosic biomass as raw materials using pyrolysis technology. Due to its rich in a variety of chemical and biological active substances, biomass is deemed to the great development potential substitute of petroleum prod? ucts. The catalytic pyrolysis of biomass is the main way to prepare high quality bio?oil. However, because of the high oxygen content of bio?oil in the catalytic conversion process, the low selectivity of target products and the easy coking and deactivation of catalysts, its application has been limited. The conversion of the biomass pyrolysis oil to high val? ue products, such as valuable bio?chemicals (benzene, toluene, xylene (BTXs), etc.) and bio?polymers, has be? come one of the important topics in recent years. In this paper, on the basis of the introduction of the mechanism of biomass pyrolysis and its reaction pathway, it was reviewed that the recent research progress on the production of high quality bio?oil from catalytic pyrolysis of lignocellulosic biomass using catalyst methods (metal based oxide catalyst, metal salts catalyst, microporous zeolite catalyst, mesoporous zeolite catalyst, etc.) including catalytic pyrolysis mechanism, transformation mechanism of products, and hydrogen donor (such as tetrahydronaphthalene, methanol, waste plastic, waste oil, etc.) including the co?catalytic pyrolysis mechanism. At the same time, the pyrolysis charac? teristics, product compositions and transformation mechanism of bio?oil into BTXs in catalytic pyrolysis process were summarized. The productions of benzene, toluene, xylene (BTXs) by ex?situ catalytic pyrolysis (online catalytic up? grading of pyrolysis vapor of biomass) and deactivation of catalysts were emphasized. Meanwhile, some problems and their solutions about catalytic pyrolysis technology of lignocellulose biomass into hydrocarbon?rich (especially BTXs) 林业工程学报第4卷bio?oil were analyzed. The development prospect was put forward, which will provide a reference for the further high? valuable utilization of lignocellulose biomass. Keywords:lignocellulosic biomass;
