Kinetic models for hydroconversion of furfural over the ecofriendly Cu-MgO catalyst: An experimental and theoretical study

Hydrogen Doping into MoO3 Supports toward Modulated Metal–Support Interactions and Efficient Furfural Hydrogenation on Iridium Nanocatalysts

“…By contrast, it shows a good linear correlation with P (Figure c), which suggests a first‐order reaction with respect to H 2 . These observations are very consistent with previously reported experimental and theoretical investigations . Therefore, the hydrogenation activity should be mainly associated with the H ads on the Ir surface.…”

“…To determine the kinetics,F AL concentration (C FAL )a nd H 2 pressure (P H 2 )w ere varied to identify any correlationsw ithr eaction rate. Similart ot he cases of a,b-unsaturateda ldehydes, [41,42] C FAL has an egligible effect on the reaction rate in the hydrogenation of FAL ( Figure 6b), which indicates that the reactiono rder with respect to furfural is almostz ero, and the chemisorption/activation of FALo nt he catalysts urface should be ar apid equilibrium step. By contrast, it shows ag ood linear correlation with P H 2 (Figure 6c), which suggests af irst-order reaction with respectt oH 2 .T hese observations are very consistent with previously reported experimental and theoretical investigations.…”

[42,43] Therefore, the hydrogenation activity should be mainly associated with the H ads on the Ir surface. According to the H 2 -TPD investigation, the Ir/HÀMoO x -400 catalyst with its high H 2 uptake, particularly the moderate chemisorbed H 2 , reasonably contributes to the high activity in FALh ydrogenation.…”

At room temperature in water: efficient hydrogenation of furfural to furfuryl alcohol with a Pt/SiC–C catalyst

“…To overcome this, chromium-free catalysts and noble metal promoted Cu-based catalysts have been developed. [11][12][13][14][15][16][17][18] For instance, Fulajtarova et al prepared a Pd-Cu/MgO catalyst for hydrogenation of FAL and a high FOL selectivity of 99% was obtained at 40 C. 13 A Cu/MgO catalyst also behaved well in the hydroconversion of FAL to FOL in vapor phase under the optimal conditions. 14,15 Besides, noble-metal catalysts also aroused intensive interests in this eld.…”

[19][20][21] Among the various noble metal catalysts, Pt-based catalysts have been widely applied in various hydrogenation reactions due to their unique properties.…”
