摘要:

生物质热解制备生物油是能源富集的有效途径,是实现碳闭路循环的重要方式,作为一种环境友好型技术受到广泛关注和研究。然而,生物质热解反应过程复杂,生成的生物油热值低、含氧量高及强酸性等特点,制约了生物油的分离提纯、制备合成气以及燃烧等方面的应用,生物油品质的提升迫在眉睫。本文从生物质三组分、原料预处理、反应参数、催化剂、反应器等方面综述了影响生物油品质的主要因素,分析了生物油的特点,不同预处理下生物质特性的变化与生物油的关系,催化剂参与的热解行为对提升生物油品质的导向作用以及常用生物质热解反应器的特点,并对影响生物油品质的主要因素进行了总结。最后,针对影响制备高品质生物油的诸多因素提出建议,以期为制备高品质生物油提供参考和借鉴。

Abstract:

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.

Key words: biomass, pyrolysis, bio-oil, pretreatment, catalyst, deactivation
