Chlorella sp. are among the highest cultivated species of microalgae. They are considered as an important functional food due to their abundance and valuable health benefits. It would be useful to develop an effective method for phenolic compound extraction from Chlorella sp. using safe technology and green solvents for the applications in food and pharmaceutical fields. Pressurized hot water extraction (PHWE) is an alternative for this purpose. PHWE was employed to extract phenolic compounds from Chlorella sp. microalgae at temperatures between 100 and 250 °C. The data collected is used to create the kinetics of the extraction process. The kinetics studies revealed that the extraction from Chlorella sp. microalgae using pressurized hot water treatment follows first-order kinetics and is strongly dependent on temperature. An increasing trend in the calculated values of mass transfer coefficient, k, was noticed, with increasing temperature. The activation energy, E_a, was calculated as 11.146 kJ/mol for the extraction treatment.

小球藻属。是最高的微藻栽培种之一。由于它们的丰富性和宝贵的健康益处，它们被认为是重要的功能性食品。这将是开发用于从酚类化合物的提取的有效方法是有用的小球藻属。在食品和制药领域中使用安全的技术和绿色溶剂。为此目的，加压热水提取（PHWE）是替代方法。用PHWE从小球藻中提取酚类化合物。微藻在100至250°C之间的温度。收集的数据用于创建提取过程的动力学。动力学研究表明，从小球藻中提取sp。使用加压热水处理的微藻遵循一级动力学，并且强烈依赖于温度。注意到传质系数k的计算值随温度的升高而增加。对于萃取处理，活化能E _a计算为11.146 kJ / mol。
