四种大型褐藻的水热液化（HTL）被用来以能源有利的方式生产生物原油和生物炭。生物原油产量在 9.8 wt% 至 17.8 wt% (daf) 之间，HHV 在 32 至 34 MJ/kg 之间，生物炭产量在 10.9 wt% 至 18.6 wt% (db) 之间，HHV 在 15.7 至 26.2 MJ/kg 之间。尝试对能耗比（ECR）指数进行修改，以便在公式中包含所用原料的比热容的计算，以及水的比热容随温度的增加。对 HTL 产品和大型藻类生化转化（如厌氧消化 (AD) 和发酵）产品的能量输出进行了比较。结果表明，HTL 比发酵和厌氧消化类似物具有更高的能量输出（HTL 和 AD 分别为 7.91 MJ/kg（海藻）和 8.25 MJ/kg（海藻））。 (C) 2014 Elsevier Ltd. 保留所有权利。
Hydrothermal liquefaction (HTL) of four brown macro-algae was used to produce bio-crude and bio-char in an energy favorable way. Bio-crude yields between 9.8 wt% and 17.8 wt% (daf) with HHVs between 32 and 34 MJ/kg and bio-char yields between 10.9 wt% and 18.6 wt% (db) with HHVs between 15.7 and 26.2 MJ/kg were produced. A modification of the energy consumption ratio (ECR) index was attempted in order to include in the formula the calculation of the specific heat capacity of the feedstock used, as well as the increase of the specific heat capacity of water with temperature. A comparison in terms of energy output was made between the products from HTL and products from bio-chemical conversion of macro-algae such as anaerobic digestion (AD) and fermentation. The results indicate that HTL has higher energy output than fermentation and analogue of that from anaerobic digestion (7.91 MJ/kg(seaweed) and 8.25 MJ/kg(seaweed) from HTL and AD respectively).
