С этой целью была определена высшая (HHVi) и низшая (LHVi) энергии сгорания отдельных компонентов растительной биомассы (лигнин, целлюлоза, гемицеллюлоза, экстрактивные вещества и др.), а также некоторых синтетических полимеров, входящих в состав пластиков. Эксперименты проводились с использованием кислородной калориметрической бомбы, а расчеты выполнялись с помощью уравнений: HHVi (kJ/g) = Eo M-1 (x + 0,295y - 0,42z) и LHVi (kJ/g) = Eo M-1 (x + 0,242y - 0,42z), где Eo = 413 kJ/mol; x, y и z - число атомов C, H и O в молекуле органического вещества или в повторяющемся звене полимера, c молекулярной массой M. Используя результаты, полученные для отдельных компонентов, была определена теплотворная способность различных биомасс и их смесей с полимерами в соответствии с правилом аддитивности: HHV = Σ(wi HHVi) и LHV = Σ(wi LVHi), где wi - массовая доля компонента в топливе. Результаты показали, что найденные значения теплотворной способности близки к экспериментальным, что свидетельствует об адекватности правила аддитивности для оценки удельной тепловой энергии сгорания твердого топлива на основе биомассы. Было также обнаружено, что топливные гранулы, состоящие из растительной биомассы и добавок пластиков, являются наиболее перспективным твердым топливом, поскольку они обеспечивают более высокую теплотворную способность и повышенную плотность тепловой энергии, чем топливо, состоящее лишь из биомассы.</p></abstract><trans-abstract xml:lang="en"><p>In this paper, solid fuels made of plant biomass or its blends with plastic additive were studied as an alternative to fossil coals. For this purpose, experimental and calculation methods were applied to determine the higher (HHVi) and lower (LHVi) heating values of individual components of plant biomass (lignin, cellulose, hemicelluloses, extractives, etc.), as well as of some components of plastics. The experiments were carried out using an oxygen bomb calorimeter, whereas calculations were performed by the equations: HHVi (kJ/g) = Eo M-1(x + 0,295y - 0,42z) and LHVi (kJ/g) = Eo M-1(x + 0,242y - 0,42z); where Eo = 413 kJ/mol, x, y and z is number of atoms C, H and O, respectively, in molecule of organic substance or in repeat unit of polymer having molecular mass M. Using the results obtained for individual components, the calorific values of various biomasses and their blends with plastic additives were found according to additivity rule, as follows: HHV = Σ(wi HHVi) and LHV = Σ(wi LVHi ), where wi is weight part of the component in the biomass sample. The results revealed that calculated calorific values for the solid fuels were close to experimentally obtained values. The obtained data evidence on adequacy of the additivity rule to evaluate the thermal energy of solid fuels based on biomass. It has been also found that fuel pellets consisting of plant biomass and plastic additive are the most promising solid fuels, since they provide a higher calorific value and increased energy density than the biomass only. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>растительная биомасса</kwd><kwd>пластик</kwd><kwd>топливные гранулы</kwd><kwd>целлюлоза</kwd><kwd>гемицеллюлоза</kwd><kwd>лигнин</kwd><kwd>экстрактивные вещества</kwd><kwd>теплотворная способность</kwd><kwd>калориметрия</kwd><kwd>расчеты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>plant biomass</kwd><kwd>plastic</kwd><kwd>fuel pellets</kwd><kwd>cellulose</kwd><kwd>hemicelluloses</kwd><kwd>lignin</kwd><kwd>extractives</kwd><kwd>calorific values</kwd><kwd>calorimetry</kwd><kwd>calculation</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">Ioelovich M.
