    Selective synthesis of amylenes: Effect of catalyst alkali exchange and activation temperature on products distribution (1991)
    Springer
    Reaction kinetics and catalysis letters 43 (1991), S. 127-131

    ISSN: 1588-2837

    Topics: Chemistry and Pharmacology
    Description / Table of Contents: Abstract Исследовали эффект обмена Na и температуры активации катализатора на селективное получение амиленов на предварительно обработанном бентоните. Селективность к 3-метилбутену-1 повышается с температурой активации катализатора. Щелочной обмен оказывает подобное влияние. Натриевый катализатор более селективен к менее замещенным продуктам, однако, его активность оказалась ниже, чем в случае кислого катализатора.
    Notes: Abstract The effect of Na-exchange and catalyst activaton temperature for selective synthesis of amylenes has been studied using a pretreated bentonite as catalyst. The selectivity to 3-methyl-1-butene rose with the catalyst activation temperatures. The alkali-exchange had a similar influence. The Na-catalyst was more selective to less substituted products, but their activity was lower than that of acidic catalysts.

    Transformation of light paraffins into aromatic hydrocarbons over H-ZSM-11 zeolite (1988)

    Description / Table of Contents: Abstract H-ZSM-11, протонно-обмененную форму цеолита ZSM-11, исследовали в превращении н-пентана, н-гексана, н-гептана и смеси легких парафинов в ароматические углеводороды в интервале температур 400–540°C и при пространственных скоростях 1 час−1. Наблюдалась Высокая селективность к BTX (80%). Выход ароматики лимитируется лишь содержанием водорода на питании и в продуктах.
    Notes: Abstract H-ZSM-11, the proton-exchanged form of ZSM-11 zeolite has been studied for conversion of n-pentane, n-hexane, n-heptane and a mixture of light paraffins to aromatic hydrocarbons, at 400–540 °C and WHSV=1 h−1, giving high selectivity to BTX (80%). The aromatic yields are apparently limited only by the hydrogen content of the feed and products.

    Description / Table of Contents: Abstract Бентонитные катализаторы, обмененные на H+ и Al3+, сравнивали с Амберлистом 15 в производстве трет-амилметилового эфира в пробочном поточном реакторе, в интервале температур 80–220°C и давлении 400 кПа. Оказалось, что бентониты, высушенные при 150°C, более селективны, чем смолы.
    Notes: Abstract H+ and Al3+ exchanged bentonite catalysts were compared in a plug flow reactor with Amberlyst 15 for the production of t-amyl methyl ether, in the range of 80–220°C and 400 kPa. It was found that bentonites were more selective than resins when they were dried at 150°C.

    Description / Table of Contents: Abstract Исследовано превращение н-пентана в ароматические углеводороды на цеолите ZSM-11, обмененным на цинк (Zn-ZSM-11). Катализатор обладает высокой активностью и селективностью в превращениях н-пентана при 538°C, 1час−1 и 1 атм. Частицы Zn оказались эффективными в активации н-пентана и превращениях промежуточных продуктов в ароматические соединения.
    Notes: Abstract The transformation of n-pentane into aromatic hydrocarbons over Zn-exchanged ZSM-11 zeolite (Zn-ZSM-11) has been studied. The catalyst exhibited a high activity and BTX selectivity for n-C5 conversion at about 538°C, 1 h−1 and 1 atm. Zn-species are effective for the activation of the n-pentane and the transformation of intermediate products into aromatic compounds.
