英文摘要 | decomposition behavior of two kinds of high-protein high-ash microalgae, including wild cyanobacteria sp. and cultivated bacillariophyta sp., was examined via hydrothermal liquefaction (htl). physicochemical properties of bio-oil were extensively investigated through various techniques. special attention was paid on transfer behavior of elements (i.e. c and n) during htl process. a maximum bio-oil yield of 21.10 wt% (cyanobacteria sp.) and 18.21 wt% (bacillariophyta sp.) on dry basis was achieved at 325 degrees c for 45-60 min, accompanying with the maximum (51.38% and 48.76%) of energy recovered in bio-oil. although high hhv (33.87-36.51 mj kg(-1)) and high h/c ratio (1.37-1.62) were estimated for bio-oil products, high n/c ratio (0.06-0.09) and nitrogen content (5.31-7.50%) negatively affected its quality. gc-ms analysis combining with ftir and nmr detection revealed that components and functional structure of bio-oils were greatly distinguished from other algae bio-oil. tg analysis showed approximate 72.32-75.79% of bio-oils was distilled in the range of 200-550 degrees c. large fraction of carbon and small fraction of nitrogen were recovered in bio-oils, together with high portion of nitrogen was enriched into aqueous liquid. this study demonstrated the feasibility of applying htl to produce bio-oil from high-protein high-ash microalgae, and the findings on bio-oil properties and transfer behavior of carbon and nitrogen supplied useful information for downstream utilization.
