PHYSICO-CHEMICAL STUDIES OF Ru-CONTAINING CATALYSTS DURING SELECTIVE HYDROGENATION OF FURFURAL
نویسندگان
چکیده
В работе проведен анализ рутений содержащих композитов 3%Ru/СПСMN270 и 3%Ru/AlO, применяемых в селективном гидрировании фурфурола фурфуроловый спирт. Для большего понятия каталитических свойств Ru-содержащих систем было проведено определение их пористости методом низкотемпературной адсорбцией азота. Полученных изотермы адсорбции-десорбции азота IV типа характеризуются наличием петли гистерезиса Н, типичного для мезопористых веществ с цилиндрическими мезопорами. The catalytic properties of the catalysts and 3%Ru/AlO were studied by selective hydrogenation furfural into alcohol. For a larger concept Ru-containing catalysts, surface porosity synthesized on its basis determined lowtemperature nitrogen adsorption. Significant hysteresis is detected, loop which can be classified in shape as H type typical an adsorbent with cylindrical (bottle-shaped) mesopores. Adsorption-desorption isotherms are suitable for isothermals IV, mesoporous substances. To some extent, pore size distribution respect to their diameter has been found.

Finding Furfural Hydrogenation Catalysts via Predictive Modelling
We combine multicomponent reactions, catalytic performance studies and predictive modelling to find transfer hydrogenation catalysts. An initial set of 18 ruthenium-carbene complexes were synthesized and screened in the transfer hydrogenation of furfural to furfurol with isopropyl alcohol complexes gave varied yields, from 62% up to >99.9%, with no obvious structure/activity correlations. Contr...

متن کاملHeterophase-structured nanocrystals as superior supports for Ru-based catalysts in selective hydrogenation of benzene
ZrO2 heterophase structure nanocrystals (HSNCs) were synthesized with tunable ratios of monoclinic ZrO2 (m-ZrO2) to tetragonal ZrO2 (t-ZrO2). The phase mole ratio of m-ZrO2 versus t-ZrO2 in ZrO2 HSNCs was tuned from 40% to 100%. The concentration of the surface hydroxyl groups on m-ZrO2 is higher than that on t-ZrO2. ZrO2 HSNCs have different surface hydroxyl groups on two crystalline phases. T...
