        <p>Производство торрефиката – это стратегически важное направление для диверсификации продукции лесного комплекса РФ. Торрефикат получают термохимическим преобразованием биомассы в среде с ограниченным содержанием кислорода. Преимущества торрефиката по сравнению с исходной биомассой – это высокие энергетическая плотность, гидрофобность и устойчивость к биологическому разложению. Цель исследования – комплексный термический анализ энергетического потенциала и характеристик термодеструкции торрефицированного биотоплива из древесины лиственницы. Приведена характеристика торрефиката, его элементный и компонентный состав, содержание оксидов металлов. Пиролитическая газовая хроматография-масс-спектрометрия идентифицировала основные органические соединения в составе пиролизных паров при 5 температурных режимах обработки (от 200 до 600 °C с шагом 100 °C). Методами термогравиметрии и дифференциальной термогравиметрии в инертной (аргон) и воздушной средах при скорости нагрева 10 °C/мин установлены температурные диапазоны процессов потери массы влаги и горения топлива и коксового остатка. Выход высококалорийных компонентов и наибольшее тепловыделение наблюдаются в интервале температур 400–500 °C. Установлено, что торрефикация позволяет получить топливо с повышенной энергетической эффективностью и улучшенными топливными характеристиками в сопоставлении с цельной древесиной. Результаты имеют практическую значимость для оценки перспектив использования торрефиката в качестве высокалорийного твердого биотоплива для энергетической утилизации на биотопливных котельных в Арктическом регионе и дают основу для исследований в данном направлении.</p>

        <p>The production of torrefied biomass is a strategically important area for diversifying the Russian forestry sector’s product range. Torrefied biomass is produced by the thermochemical biomass conversion in an oxygen-limited environment. High energy density, hydrophobicity, and resistance to biological degradation are among the advantages of torrefied biomass over raw biomass. The research is aimed at carrying out a comprehensive thermal analysis of the energy potential and thermal degradation parameters of torrefied biofuel produced from larch wood. The paper presents the characteristics of torrefied biomass, its elemental and compositional structure, and its metal oxide content. Pyrolysis gas chromatography-mass spectrometry determined the main organic compounds present in pyrolysis vapors at five different temperature settings (ranging from 200 to 600 °C with a 100 °C step) during processing. The temperature ranges for moisture loss and the combustion of fuel and coke residue were determined using thermogravimetry and differential thermogravimetry in an inert (argon) and air atmosphere at a heating rate of 10 °C/min. The release of high-calorie components and the greatest heat release occur in the 400–500 °C temperature range. It has been found that torrefaction produces a fuel with higher energy efficiency and improved fuel properties compared to solid wood. The results have practical significance for assessing the potential of torrefied biomass as a high-calorific-value solid biofuel for energy recovery at biofuel boiler plants in the Arctic region and provide a basis for further research in this area.</p>
