Топливо, получаемое из микроводорослей, называется "биотопливом третьего поколения". Этот вид биомассы не является основным сырьем для питания и выращивается обычно на непригодных для растениеводства участках. Продуктивность микроводорослей (на единицу площади, используемой для выращивания) биомассой и жирами (липидами) в десятки раз превышает соответствующий выход наземной биомассы. В последние годы все большее внимание привлекают гидротермальные технологии как перспективные способы переработки биомассы микроводорослей в биотопливо. Однако наиболее привлекательной технологией является гидротермальное сжижение (ГТС) микроводорослей с получением жидкого биотоплива (бионефти) в качестве целевого продукта. Одним из основных преимуществ технологии ГТС является то, что в выход бионефти вносят вклад не только липиды, но и углеводы и белки, что увеличивает общий выход продукта. В представленной работе проведено экспериментальное исследование процесса гидротермального сжижения (ГТС) биомассы микроводорослей Arthrospira platensis с получением массовых данных выхода продуктов и дальнейшее исследование продуктов данного процесса методами термогравиметрического анализа и калориметрии, с определением влияния параметров процесса на выход и качество продуктов.</p></abstract><trans-abstract xml:lang="en"><p>Microalgae biomass is one of the most promising sources of renewable biofuels. The fuel produced from microalgae is called "third-generation biofuels". This type of biomass is not the main raw material for food and is usually grown in areas unsuitable for crop production. The productivity of microalgae (per unit area used for cultivation) with biomass and fats (lipids) is ten times higher than the corresponding yield of terrestrial biomass. In recent years, hydro thermal technologies have attracted increasing attention as promising ways to process microalgae biomass into biofuels. However, the most attractive technology is hydrothermal liquefaction (HTL) of microalgae to produce liquid biofuels (bio-oil) as the target product. One of the main advantages of GTS technology is that not only lipids, but also carbohydrates and proteins contribute to the yield of bio-oil, which increases the overall yield of the product. In this paper, an experimental study of the hydrothermal liquefaction (HTL) process of microalgae biomass Arthrospira platensis was performed to obtain mass data on the yield of products and further study of the products of this process using thermogravimetric analysis and calorimetry, with the determination of the effect of process parameters on the yield and quality of products.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бионефть</kwd><kwd>гидротермальное сжижение</kwd><kwd>биомасса микроводорослей</kwd><kwd>термогравиметрический анализ</kwd><kwd>калориметрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bio-oil</kwd><kwd>hydrothermal liquefaction</kwd><kwd>biomass of microalgae</kwd><kwd>thermogravimetric analysis</kwd><kwd>calorimetry</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта Российского Фонда Фундаментальных Исследований (РФФИ) (проект № 18-58-45009)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Demirbas, A., 2009.
