微藻被认为是用于生物柴油生产和生物产品的有前景的脂质来源。本文研究了受控微波辐射下微藻浆料的加工。应用微波功率以在 12 分钟的恒定停留时间下达到 80、100、120 和 140 摄氏度的温度。微波辐射导致藻类细胞壁破裂，从而促进脂质提取。评估了三种菌株的无机材料对微波加热的影响，包括微拟球藻、Fritschii 绿球藻和椭圆拟毛囊藻。计算了质量平衡，结果表明残留物中回收的碳、氮和总质量高度依赖于工艺条件和藻类菌株。水热微波处理（HMP）被发现是水热液化以及脂质和植物化学物质提取的有效预处理。 (C) 2013 Elsevier Ltd. 保留所有权利。
Microalgae are regarded as a promising source of lipids for bio-diesel production and bio-products. The current paper investigates the processing of microalgal slurries under controlled microwave irradiation. Microwave power was applied to reach temperatures of 80, 100, 120 and 140 degrees C at a constant residence time of 12 min. Microwave irradiation led to disruption of the algal cell walls which facilitated lipid extraction. The influence of inorganic material on microwave heating was assessed for three strains including, Nannochloropsis occulata, Chlorogloeopsis fritschii and Pseudochoricystis ellipsoidea. Mass balances were calculated and showed that the amount of carbon, nitrogen and total mass recovered in the residue was highly dependent on process conditions and algae strain. Hydrothermal microwave processing (HMP) was found to be an effective pre-treatment for hydrothermal liquefaction and extraction of lipids and phytochemicals. (C) 2013 Elsevier Ltd.
