Abstract In this study, the recovery of algal oil from Enteromorpha intestinalis based on an acidic–hydrothermal reaction was investigated. Overall, the algal oil yield after the acidic– hydrothermal reaction was increased under the conditions of high reaction temperature, high catalyst concentration, and long reaction time within the tested ranges. Significantly, catalyst concentration, compared with reaction temperature and time, less affected algal oil recovery. The optimal acidic–hydrothermal reaction conditions for production of algal oil from E. intestinalis were as follows—200 °C reaction temperature, 2.92 % catalyst concentration, 54 min reaction time. Under these conditions, an 18.6 % algal oil yield was obtained. By increasing the combined severity factor, the algae oil recovery yield linearly increased. Keywords Enteromorpha intestinalis .

Introduction Marine biomass use in the food, chemical, and pharmaceutical industries has been widely expanded [1, 2]. Recently too, in the bioenergy field, marine biomass in the forms of macroand micro-algae have been effectively and consistently introduced as feedstock resources [3–6]. Marine biomass compared with land-based biomass offers the key advantages of a faster growth rate and higher productivity. The contents and compositions of the carbohydrate G.
