چکیده
A silica-supported copper (Cu/SiO2) catalyst containing highly dispersed Cu nanoparticles was prepared via a crown-ether-assisted impregnation method. 12-crown-4-ether-assisted Cu/SiO2 outperformed several catalysts with various organic additives in the dehydrogenation of 2,3- and 1,4-butanediol. It found that catalytic activity, i.e., formation rate acetoin from 2,3-butanediol γ-butyrolactone 1,4-butanediol, proportional to surface area.

Methane oxy-steam reforming over a highly efficient Ni/Al2O3 nanocatalyst prepared by microwave-assisted impregnation method
An alumina-supported nickel catalyst was prepared by impregnation of Ni2+ solution onto mesoporous alumina under microwave irradiation (denoted as M-Ni/Al2O3). For comparison, a catalyst with the same nickel content was prepared by conventional impregnation method (denoted as UM-Ni/Al2O3). Both M-Ni/Al2O3 and UM-Ni/Al2O3 catalysts were applied to the syngas (H2 + CO) production by methane oxy-s...
متن کاملActivity of a Te-MgO Catalyst Prepared by Adsorption of Te Vapor onto MgO: Dehydrogenation Activity for Aromatic Hydrocarbons
The activity of a Te-MgO catalyst prepared by adsorbing Te vapor onto MgO powder was determined by dehydrogenation of indane, 9,10-dihydrophenanthrene, cumene, and p-cymene. The activity of the Te-MgO catalyst was higher than that of the MgO catalyst in most of the cases investigated. The selectivity of the former catalyst was much higher than that of the later in all cases studied. The Te-MgO ...

Catalytic performance and the nature of surface adsorbates were investigated for high-surface-area ceria during the ethylbenzene oxidative dehydrogenation (ODH) reaction using CO2 as a soft oxidant. The high surface area ceria material was synthesized using a template-assisted method. The interactions among ethylbenzene, styrene, and CO2 on the surface of ceria and the role of CO2 for the ethyl...
