Высокой каталитической активностью обладают высокодисперсные частицы палладия, однако вследствие их электронодефицитности поверхность палладиевых частиц подвергается блокированию ненасыщенными углеводородами. В данной работе методами ТПД NH3, ПЭМ и РФЭС исследованы алюмопалладиевые катализаторы, носители которых имеют различную кислотность в результате их химического модифицирования разными реагентами. Проведены каталитические испытания образцов в реакции гидрирования бутадиена-1,3 в лабораторных условиях. Катализаторы на носителях с кислотными модификаторами показали низкую конверсию бутадиена-1,3 и более высокую селективность по бутену-1 в сравнении с немодифицированным образцом. Катализаторы на носителях, обработанных оснóвными добавками, обеспечивают высокую степень превращения бутадиена-1,3 с сохранением значений селективностей по бутену-1 и бутану.</p></abstract><trans-abstract xml:lang="en"><p>Studies of the influence of acidity of alumina supports on properties of supported palladium particles were aimed at improving the activity of catalysts for hydrogenation of unsaturated hydrocarbons of pyrolysis gasoline fraction. High-disperse palladium particles demonstrate the high catalytic activity but their electron deficiency make them suffering from blocking with unsaturated hydrocarbons. NH3 TPR, TEM and XPS techniques were used for studying aluminopalladium catalysts; different acidities of the catalyst supports resulted from their chemical modification with various agents. The catalysts were tested for lab-scale hydrogenation of butadiene-1,3. Against the non-modified samples, the catalysts supported on modified alumina provided a lower conversion of butadiene-1,3 but a higher selectivity to butene-1. A higher conversion of butadiene-1,3 at the preserved selectivity to butene-1 and butane was observed in the presence of the catalyst supported on base-modified alumina.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гидрирование бутадиена</kwd><kwd>модифицирование γ-Al2O3</kwd><kwd>ТПД NH3</kwd><kwd>ПЭМ</kwd><kwd>РФЭС</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hydrogenation of butadiene</kwd><kwd>modifying of γ-Al2O3</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">Moyes R.B., Wells P.B., Grant J., Salman N.Y. // Appl.
