摘　　要：微藻是一类单细胞或简单多细胞的微生物,其生长快速,并能够高效地固定各种来源的CO2,包括大气和工厂排放废气中所含的CO2及溶解性的碳酸盐。CO2的固定、生物能源的制备及污水的处理相结合为目前CO2的减排提供了一种前景非常好的技术选择。论述了热化学转化法(湿式碳化、热解及直接液化)等微藻生物质制备生物能源方法的研究状况,并分析了利用微藻生物减排CO2与污水处理相结合的可能性及目前的研究进展。Microalgae are a group of prokaryotic or eukaryotic photosynthetic microorganisms composed of uni cellular or simple muhicellular structure. They grow rapidly and can fix CO2 from different sources of atmosphere,industrial exhaust gases and soluble carbonate salts efficiently. The combination of CO2 fixation, biofuel production, and wastewater treatment provide a very promising alternative to current CO2 mitigation strategies. Base on the comprehensive literature review, this paper summarize current study of thermochemical conversion microalgae biomass into biofuels, including hydrothermal carbonization, pyrolysis and direct liquefaction, analyze the feasibility of combining CO2 bio-mitigation with wastewater treatment.
