摘要
介绍了生物质液化过程的最新研究进展;分析了原料种类、溶剂、催化剂、反应温度、反应压力、反应时间、反应器类型对高压液化过程以及产品组成和收率的影响;对生物质液化的机理进行了剖析;对生物质液化制生物原油过程进行了展望,认为降低生物原油的生产成本、降低生物原油中的氧含量是生物质液化的发展方向。
There is plentiful biomass, a renewable resource, in the world. Not only the problem of energy shortage can be solved, but also the amount of emission of carbon dioxide can be decreased by the effective utilization of biomass energy. Thermochemical conversion of biomass includes gasification, pyrolysis and liquefaction. Liquefaction has got more and more attention in recent years because of its advantages over other methods. In this paper, the progress in liquefaction of biomass is reviewed, including the effects ofbiomass type, solvent, catalyst, temperature, pressure, and reaction time on the yield and distribution of products. It is pointed out that the mainstream of liquefaction is to reduce the cost of liquefaction and decrease the oxygen content of bio - crude.
