При этом пищевые отходы являются потенциальным возобновляемым источником для получения зеленого водорода путем их темновой ферментации (ТФ). Последние исследования по интенсификации ТФ показали высокий потенциал процесса, сравнимый с электролизом по эффективности. Однако, несмотря на эффективность процесса ТФ, одним из препятствий для его внедрения является наличие в водородсодержащем биогазе значительного (до 94%) содержания углекислого газа. Таким образом, для дальнейшего использования биоводорода требуется его очистка от углекислого газа. В статье показано, что для очистки водородсодержащего биогаза наиболее приемлемо использование химического поглотителя, однако данный способ необходимо улучшить за счет применения принципов зеленой химии с возможностью дальнейшего использования улучшенного способа очистки в рамках циркулярной экономики. Целью данного исследования являлась разработка концепции электрохимического кондиционирования биоводорода, получаемого в процессе ТФ с использованием принципов циркулярной экономики и зеленой химии. Концепция предполагает очистку биоводорода при уменьшении выбросов углекислого газа в атмосферу на основе использования промежуточного носителя СО2 для последующей его утилизации в фотобиореакторе. На основе химизма процесса разработан материальный баланс процесса. Для экспериментального подтверждения возможности кондиционирования биогаза в соответствии с представленной концепцией разработана экспериментальная установка. В среднем степень удаления СО2 составила 68% при содержании биоводорода после электрохимического кондиционирования 84,9%. Полученные данные говорят о возможности использования разработанной системы для очистки биоводорода, полученного в процессе темновой ферментации, однако требуется модернизация и оптимизация отдельных элементов разработанной системы, что планируется в дальнейших исследованиях.</p></abstract><trans-abstract xml:lang="en"><p>The production and accumulation of food waste is growing annually, posing a threat to humanity and the environment. Food waste is also a potential renewable source for producing green hydrogen through dark fermentation (DF). Recent studies on DF intensification have demonstrated the high potential of the process, comparable in efficiency to electrolysis. However, despite the efficiency of the DF process, one of the obstacles to its implementation is the significant (up to 94%) carbon dioxide (CO2) content in hydrogen-containing biogas. Therefore, for further use of biohydrogen, it must be purified from CO2. This article demonstrates that the use of a chemical adsorbent is most suitable for purifying hydrogen-containing biogas. However, this method needs to be improved through the application of green chemistry principles, with the possibility of further use of the improved purification method within the framework of a circular economy. The objective of this study was to develop a concept for the electrochemical conditioning of biohydrogen obtained through DF using the principles of a circular economy and green chemistry. The concept involves purifying biohydrogen while reducing CO2 emissions into the atmosphere using an intermediate carrier of carbon dioxide for subsequent utilization in a photobioreactor. A material balance was developed based on the process chemistry. A pilot plant was designed to experimentally validate the feasibility of biogas conditioning according to the presented concept. The average CO2 removal rate was 68%, with a biohydrogen content of 84.9% after electrochemical conditioning. The obtained data indicate the feasibility of using the developed system for purifying biohydrogen obtained during dark fermentation. However, modernization and optimization of individual system components is required, which is planned for future research.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>темновая ферментация</kwd><kwd>биоводород</kwd><kwd>биогаз</kwd><kwd>электролиз</kwd><kwd>электрохимическое кондиционирование</kwd><kwd>едкий натр.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dark fermentation</kwd><kwd>biohydrogen</kwd><kwd>biogas</kwd><kwd>electrolysis</kwd><kwd>electrochemical conditioning</kwd><kwd>caustic soda</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Abu Hatab A., Cavinato M.
