Паровая конверсия метана – доминирующий способ получения водорода. Значительная доля этого процесса в мировых выбросах CO2 задаёт важность оптимизации его технологических параметров для снижения экологического воздействия. Разработанная многокомпонентная модель паровой конверсии метана в COMSOL Multiphysics актуальна не только благодаря ее применимости к оптимизации существующих производственных установок, но и потенциалом для разработки новых методов утилизации попутного нефтяного газа. В контексте импортозамещения в сфере водородной энергетики данная модель также представляет собой интерес, позволяя рассчитывать технологические параметры промышленных установок.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ.

Методология исследования включает в себя использование экспериментальных данных из литературы и промышленных показателей для интеграции в многокомпонентную модель в COMSOL Multiphysics. Это обеспечивает моделирование сложных химических взаимодействий в условиях, характерных для промышленного процесса паровой конверсии.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. Разработанная многокомпонентная модель позволяет рассчитывать ключевые параметры процесса паровой конверсии метана, включая концентрацию компонентов (метана, водорода, монооксида и диоксида углерода) и  температуру  по  длине  реактора.  Модель  успешно  описывает  химические взаимодействия между компонентами и учитывает влияние операционных условий, таких как температура, давление и соотношение пар/газ, на эффективность процесса. Верификация модели осуществлялась путем сравнения результатов моделирования с экспериментальными данными и показателями реальных промышленных процессов. Их соответствие подтверждает высокую степень достоверности и пригодность модели для практического применения в инженерных расчетах и оптимизации процессов паровой конверсии метана.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ.

Существует также потенциал применения модели для расчёта ступеней установок по утилизации продуктов переработки попутного нефтяного газа.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>RELEVANCE</title><p>RELEVANCE. Steam methane reforming is the dominant method of hydrogen production. Its significant share in global CO2 emissions highlights the importance of optimizing technological parameters to reduce environmental impact. The developed multi-component model of steam methane reforming in COMSOL Multiphysics is relevant not only due to its applicability for optimizing existing production facilities but also for its potential in developing new methods for utilizing associated petroleum gas. In the context of import substitution in the hydrogen energy sector, this model is also of interest, allowing for the calculation of technological parameters of industrial installations.</p></sec><sec><title>THE PURPOSE</title><p>THE PURPOSE. The aim of the work is to develop and verify a multi-component model of steam methane reforming.</p></sec><sec><title>METHODS</title><p>METHODS. The research methodology includes the use of experimental data from the literature and industrial indicators for integration into a multi-component model in COMSOL Multiphysics. This enables the modelling of complex chemical interactions under conditions characteristic of the industrial steam methane reforming process.</p></sec><sec><title>RESULTS</title><p>RESULTS. The developed multi-component model allows calculating key parameters of the steam methane reforming process, including the concentration of components (methane, hydrogen, carbon monoxide, and carbon dioxide) and temperature along the reactor. The model successfully describes the chemical interactions between components and takes into account the influence of operating conditions, such as temperature, pressure, and steam/gas ratio, on process efficiency. The model verification was carried out by comparing the modelling results with experimental data and indicators of real industrial processes. Their correspondence confirms the high degree of reliability and suitability of the model for practical application in engineering calculations and optimization of steam methane reforming processes.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION. The conclusions made based on the modelling can be used for further improvement of methane conversion technologies, contributing to their efficiency and environmental friendliness. There is also potential for using the model to calculate the stages of installations for the utilization of products from the processing of associated petroleum gas.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>паровая конверсия метана</kwd><kwd>COMSOL Multiphysics</kwd><kwd>верификация модели</kwd><kwd>многокомпонентное моделирование</kwd><kwd>химическая кинетика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>methane steam reforming</kwd><kwd>multi-component modeling</kwd><kwd>COMSOL Multiphysics</kwd><kwd>model verification</kwd><kwd>chemical kinetics</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Результаты получены при финансовой поддержке Минобрнауки «Изучение процессов в гибридной энергетической установке топливный элемент – газовая турбина» шифр проекта FZSW-2022-0001.</funding-statement><funding-statement xml:lang="en">The results were obtained with financial support from the Ministry of Science and Higher Education «Study of processes in a hybrid power plant fuel cell – gas turbine» project code FZSW-2022-0001.</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">Lemus R.G., Duart J.M.M.
