A range of model biochemical components, microalgae and cyanobacteria with different biochemical contents have been liquefied under hydrothermal conditions at 350 °C, ∼200 bar in water, 1M Na(2)CO(3) and 1M formic acid. The model compounds include albumin and a soya protein, starch and glucose, the triglyceride from sunflower oil and two amino acids. Microalgae include Chlorella vulgaris,Nannochloropsis occulata and Porphyridium cruentum and the cyanobacteria Spirulina. The yields and product distribution obtained for each model compound have been used to predict the behaviour of microalgae with different biochemical composition and have been validated using microalgae and cyanobacteria. Broad agreement is reached between predictive yields and actual yields for the microalgae based on their biochemical composition. The yields of bio-crude are 5-25 wt.% higher than the lipid content of the algae depending upon biochemical composition. The yields of bio-crude follow the trend lipids>proteins>carbohydrates.
在 350°C、200 巴的水、1M Na(2)CO(3)和 1M 甲酸的水热条件下，液化了一系列具有不同生化成分的模型生化成分、微藻和蓝藻。模型化合物包括白蛋白和大豆蛋白、淀粉和葡萄糖、葵花籽油中的三酸甘油酯以及两种氨基酸。微藻包括普通小球藻、隐甲藻和紫球藻，以及蓝藻螺旋藻。每种模型化合物的产率和产物分布都用于预测具有不同生化组成的微藻的行为，并使用微藻和蓝藻进行了验证。根据生化组成，微藻的预测产率与实际产率之间达成了广泛的一致。生物原油的产率比藻类的脂质含量高 5-25wt.%，具体取决于生化组成。生物原油的产率遵循脂质>蛋白质>碳水化合物的趋势。
