Ранее компьютерным моделированием было установлено, что восстановление железа из магнетита углеродом начинается при 680 °С, а восстановление его водородом – при 350 °С. В данной работе показано, что начало восстановления железа метаном следует ожидать при температуре 530 °С. Однако для природного газа, полученного из газоконденсатных месторождений и содержащего до 10 % тяжелых углеводородов и примесей, указанная температура возрастает до 550 °С. При использовании природного газа совместно с кислородом в со- отношении СН4 : О2 = 2:1 температура начала восстановления также возрастает до 620 °С. Кроме того, предложена расчетная формула для системы Fe – O – C – H, позволяющая прогнозировать образование «чистой» фазы железа при 1500 °С на основании химического состава восстановительной газовой смеси.</p></abstract><trans-abstract xml:lang="en"><p>The main component of natural gas is methane CH4 , that is, a component consisting of two active reducing agents for iron – carbon and hydrogen. Previously, computer simulations have found that the reduction of iron from magnetite with carbon begins at 680 °C, and its reduction with hydrogen – at 350 °C. In this paper it is shown that the beginning of the reduction of iron with methane should be expected at a temperature of 530 °C. However, this temperature for natural gas, obtained from gas condensate fields and containing up to 10 % of heavy hydrocarbons and impurities, increases to 550 °C. When using natural gas together with oxygen in the ratio CH4 : O2 = 2:1, temperature of the beginning of reduction also increases to 620 °C. In addition, a calculation formula was proposed for Fe – O – C – H system, which allows predicting the formation of a “pure” phase of iron at 1500 °C based on the chemical composition of the reducing gas mixture.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>природный газ</kwd><kwd>восстановление железа</kwd><kwd>бескоксовая металлургия</kwd><kwd>компьютерное моделирование</kwd><kwd>химические реакции</kwd><kwd>температура процесса</kwd><kwd>критерий восстановления</kwd></kwd-group><kwd-group xml:lang="en"><kwd>natural gas</kwd><kwd>iron reduction</kwd><kwd>coke-free metallurgy</kwd><kwd>computer modeling</kwd><kwd>chemical reactions</kwd><kwd>process temperature</kwd><kwd>reduction criterion</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">Справочник химика.
