【摘要】：以微拟球藻为原料,研究微藻水热液化过程中多种参数对水热液化后有机物回收率的影响,包括温度、时间、溶剂比和pH等,从而获得微藻水热液化后有机物的最佳回收工艺条件。结果显示,在室温下进行有机相回收,保证回收溶剂比为20∶1(溶剂/水相不溶物;v/wt)、停留时间为10min、回收pH7,即可达到最佳回收效果。最佳条件下水热液化有机相的回收率为34%左右,且不同的回收温度和pH值对回收的有机相组分均会产生影响。
[Abstract]:The effects of various parameters on the recovery of organic matter after hydrothermal liquefaction of microalgae, including temperature, time, solvent ratio and pH, were studied by using Chlorella microphylla as raw material. The optimum recovery conditions of organic matter after hydrothermal liquefaction of microalgae were obtained. The results show that when organic phase is recovered at room temperature, the recovery solvent ratio is 20:1 (solvent / water phase insoluble matter: v / wt) and the residence time is 10 min, the recovery of pH7, can achieve the best recovery effect. The recovery rate of the organic phase was about 34% under the optimum conditions, and the recovery temperature and pH value had an effect on the recovery of the organic phase.
