Biomass fast pyrolysis liquefaction to obtain biological oil is a mixture of water and hundreds of organic compounds, can be used as liquid fuel or chemical raw materials used in different fields. In order to increase the application value of the bio-oil, on the one hand, the biological oil can be refined, on the other hand can target specific biomass raw materials, selective control pyrolysis reaction process, thereby gaining specific high grade oil. With the improvement of catalyst preparation, a variety of new king of catalysts were introduced to the field of biomass pyrolysis. Recently, some researches had reported that some chemicals can be selectively promoted by introducing specific technology during pyrolysis process. Using this technology, chemical-riched liquid would be produced and the following purification process would be greatly simplified. Hence, developing new kind of technique with high selectivity to realize a variety of chemical preparation will be an inexorable trend in the field of biomass pyrolysis.
