“…Our previous investigation showed that Y zeolite modified by ammonium fluoride and phosphorus also showed relatively high alkylation activity despite serious deactivation within a short time. 21,22 To the best of our knowledge, the composite catalyst of super acid-loaded HUSY zeolite for the alkylation of isobutene/1-butene has hardly been reported to date, although this kind of composite catalyst was used for other catalytic reactions reviewed above. The object of the present work was to investigate the alkylation performance of the prepared SZ/ USY composite catalyst and elucidate the mechanism of alkylation activity improvement.…”

The composite catalyst SO 4 2− /ZrO 2 /H-ultra Y zeolite (denoted SZ/HUSY) was prepared and first used in the isobutane/1-butene alkylation reaction. The alkylation performance of the composite catalyst was compared with that of SZ and HUSY. The prepared catalysts were characterized by X-ray diffraction (XRD), Py-IR, NH 3 -TPD, and so on. The experiment showed that high SZ loading destroyed the crystalline structure and morphology of HUSY, while 5% SZ loading could maintain the favorable structure of HUSY and modified acidity. More important was that 5SZ/HUSY showed better alkylation performances than SZ and HUSY. Much fewer C 5 −C 7 hydrocarbons (i.e., 14% selectivity) than over SZ and fewer C 9 + hydrocarbons (i.e., about 16%) than over HUSY were produced, and more C 8 hydrocarbons (c.a 70% yield) were formed over 5SZ/HUSY. However, the catalyst still deactivated rapidly. The regeneration performance was evaluated herein. The deactivated catalyst could recover its catalytic activity after several times of reaction−regeneration. The favorable alkylation performances of the prepared composite catalyst 5SZ/HUSY should be attributed to the creation of more medium and strong acid sites and fewer super acid sites, which should result from the interaction between SZ and HUSY. It provided a new way to improve the alkylation performance of solid acid catalysts.

в начале 90-х годов ХХ в., ее основные положения непрерывно эволюционировали и развивались. На данный момент насчитывается 10–12 основных "краеугольных камней7quot;, на которых должен быть построен идеальный химический процесс. Данный обзор анализирует накопленный опыт и достижения на пути к созданию химических продуктов и процессов без использования или образования вредных веществ. Обзор представляет точку зрения ведущих российских специалистов, работающих в различных областях данного направления, включая гомогенный и гетерогенный катализ, тонкий и промышленный органический синтез, электрохимию, полимерную химию, химию на основе биовозобновляемого сырья, химию энергоемких соединений и материалов. Представлена также новая разработка российских авторов в области количественной оценки экологичности процессов.<br> Библиография — 1761 ссылка.
