摘要：
Preparation of bio-oil by biomass pyrolysis is an effective way to enrich energy and realize the closed cycle of carbon, which has been widely concerned and studied as an environmental friendly technology. However, the process of biomass pyrolysis is very complex, and the resulting bio-oil shows low heat value, high oxygen content and strong acidity, which restricts the separation and purification, producing syngas and combustion. Therefore, the improvement of bio-oil quality is more urgent. In this paper, the main factors affecting the quality of bio-oil are reviewed from the aspects of three components, raw material pretreatment, reaction parameters, catalysts and reactors. In addition, this article analyzes characteristics of bio-oil and the relationship to the change of biomass properties under different pretreatment, the guiding effect of improving bio-oil quality in pyrolysis behavior involving catalysts, and the advantages and disadvantages of commonly used biomass pyrolysis reactors. Finally, it summarizes the main factors that affects the quality of bio-oil. Then, some suggestions for affecting the production of high quality bio-oil are put forward, which is expected to provide reference for the production of high quality bio-oil. © 2021, Chemical Industry Press Co., Ltd.
