Проведено сравнение каталитических свойств бифункциональных катализаторов 7%Mo2C/SAPO-31 (LCCH-2) и 7%Mo2C/SAPO-11 (LCCH-2-2) в процессе гидроизомеризации дизельных фракций в области температур 320–400 °С. Показано, что при температурах выше 320 °С катализатор LCCH-2 обеспечивает более высокий выход гидроизомеризованной дизельной фракции и более низкую температуру ее застывания по сравнению с катализатором LCCH-2-2. Проведен анализ соотношения суммы моноизомеров и суммы диизомеров в продуктах реакции, сделан вывод, что катализатор на основе SAPO-31 более селективен по отношению к образованию терминальных монозамещенных алканов, чем катализатор на основе SAPO-11. Исследована устойчивость обоих катализаторов к дезактивации коксовыми отложениями (100-часовые испытания при 320 и 360 °С в процессе гидроизомеризации): установлено, что образец LCCH-2-2 менее устойчив к дезактивации, чем LCCH-2. Наблюдаемые закономерности обусловлены различиями в кислотности, степени гомогенности распределения кислотных и гидрирующих-дегидрирующих центров в исследуемых катализаторах и структурным типом кислотного носителя.</p></abstract><trans-abstract xml:lang="en"><p>Part 3 of the studies dealt with catalytic properties of the new catalysts based on molylbdenum carbides, resistant to sulfur compounds and providing manufacturing of low pour point diesel fuel with the quality indices identical to those obtained with platinum-containing catalysts. Catalytic properties of bifunctional catalysts 7%Mo2C/SAPO-31 (LCCH-2) and 7%Mo2C/SAPO-11 (LCCH-2-2) for hydroisomerization of diesel fractions were compared at the temperature range between 320 and 400 °C. It was shown that at above 320 °C the catalyst LCCH-2, against LCCCH-2-2, provided the formation of the hydroisomerized diesel fraction at a higher yield and freezing at a lower temperature. Inspection of the data on the ratio of total quantities of monomers and diisomers in the reaction products led to conclude that the former catalyst is more selective than the latter to the formation of terminal monosubstituted alkanes. Studies of the stability of both catalysts to deactivation with coke deposits (100 hour testing at 320 and 360 °C during hydroisomerization) revealed that LCCH-2-2 is less stable to deactivation than LCCH-2. The observed regularities were accounted for by differences in the acidities, degree of homogeneity of distribution of acid and hydrating-dehydrating centers through the catalysts under study, and types of structures of the acid support.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>молибден</kwd><kwd>карбиды</kwd><kwd>кислотный носитель</kwd><kwd>силикоалюмофосфаты</kwd><kwd>бифункциональный катализатор</kwd><kwd>гидроизомеризация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>molybdenum</kwd><kwd>carbides</kwd><kwd>acidic support</kwd><kwd>silicoaluminophosphates</kwd><kwd>bifunctional catalyst</kwd><kwd>hydroisomerization</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">Parlitz B., Schreier E., Zubowa H.L., Eckelt R., Lieske E., Lischke G., Fricke R. // J.
