Conversion of diols by dehydrogenation and dehydration reactions on silica-supported copper catalysts

Conversion of 2,3-butanediol to butenes over bifunctional catalysts in a single reactor

“…It has been reported that dehydration of diols will occur on silica-supported copper catalysts since Cu is a Lewis acid [63]. Hence, Cu is active for both hydrogenation [28][29][30][31][32] and dehydration reactions.…”

Conversion of Biomass-Derived 2-Hexanol to Liquid Transportation Fuels: Study of the Reaction Mechanism on Cu–Mg–Al Mixed Oxides

“…Details are described in [10,18]. In the TPR experiments, a reducing mixture of 5 % H 2 /Ar at a flow rate of 50 cm 3 /min was used; the reactor was loaded with a molar amount of copper (150 lmol) so that to meet the criteria of Monti et al [19] and Malet et al [20].…”

“…High-surface area magnesium oxide was prepared by hydration with distilled water of low-surface area commercial MgO (Carlo Erba 99 %; 27 m 2 /g) and further decomposition of the resulting Mg(OH) 2 in a N 2 flow for 18 h at 773 K [17]. The silica-supported 8.5CuSi catalyst with 8.5 wt% Cu was prepared by ion exchange through the so called ''chemisorptionhydrolysis'' technique, using a Evonik Aerosil 380 silica support, as described in [18]. Samples were sieved to retain particles in the 0.177-0.500 mm range and this fraction was used in the characterization experiments.…”

Liquid transportation fuels from biomass-derived oxygenates: Gas-phase 2-hexanol upgrading on Cu-based mixed oxides

“…In the TPR experiments, a reducing mixture of 5% H 2 /Ar at a flow rate of 50 cm 3 /min was used; the reactor was loaded with a molar amount of copper (150 mol) [17] so that to meet the criteria of Monti et al [18] and Malet et al [19]. A heating rate of 10 K/min from 298 to 653 K was used.…”
