Хелатное соединение железа с гуминовой кислотой (НА), макромолекулы которого имеют радиус в диапазоне 6–50 нм, является действительно высокодисперсным. Fe2+ или Fe3+ тонко диспергированы в матрицу НА путем ионного обмена с –COOH группами или хелата с карбонильной группой в макромолекулах НА. Частицы железа до и после хелатирования с гуминовой кислотой охарактеризованы методами РФА и ИК-фурье-спектроскопии. Установлено, что в HA-Fe присутствуют α-FeOOH, ферригидрит и аморфное железо. Лабораторные испытания показали, что катализатор HA-Fe проявляет высокую каталитическую активность в сжижении углей, конверсия угля и выход бензина существенно улучшены.</p></abstract><trans-abstract xml:lang="en"><p>Research to increase the activity of iron based catalysts focuses on decreasing the particle size, increasing catalyst dispersion. The chelate compound of iron with humic acid (HA), which macromolecules radii can range from 6 to 50 nm, is truly in a highly dispersed state. Fe2+ or Fe3+ were dispersed finely into the HA matrix through the ion exchange with –COOH groups or chelate with carbonyl group in humic acid macromolecules. X-ray diffraction (XRD) and FT-IR spectrophotometer were used to characterize iron species before or after chelating with humic acid. The results indicate that there exist α-FeOOH, ferrihydrite and amorphous iron in HA-Fe. Most of the work has been conducted on a laboratory scale, and the results show that HA-Fe catalyst was approved for its excellent catalytic activity in coal liquefaction, and the conversion and oil yield of coal have been greatly improved.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гуминовая кислота</kwd><kwd>катализатор гуминовая кислота-Fe</kwd><kwd>катализаторы</kwd><kwd>сжижение углей</kwd></kwd-group><kwd-group xml:lang="en"><kwd>humic acid</kwd><kwd>humic acid-Fe catalyst</kwd><kwd>catalysis</kwd><kwd>coal liquefaction</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">Cugini A.V., Krastma D., Lett R.G., Balsone V.D. // Catal.
