Butanol synthesis from ethanol over CuMgAl mixed oxides modified with palladium (II) and indium (III)
(2018-08-01)
Ethanol conversion to butanol was investigated over mixed oxides derived from hydrotalcites modified with copper, palladium or indium. The reaction was carried out in the 403–573 K temperature range using stainless steel ...
Effect of the ZrO2 phase on the structure and behavior of supported Cu catalysts for ethanol conversion
(2013-08-06)
The effect of amorphous (am-), monoclinic (m-), and tetragonal (t-) ZrO2 phase on the physicochemical and catalytic properties of supported Cu catalysts for ethanol conversion was studied. The electronic parameters of ...
