High-yield production of 2,5-dimethylfuran from 5-hydroxymethylfurfural over carbon supported Ni–Co bimetallic catalyst

Selective hydrogenolysis of 5-hydroxymethylfurfural to 2,5-dimethylfuran over Co3O4 catalyst by controlled reduction

“…MFA is a key precursor to be converted into DMF, which meant that HMF was transformed into MFA directly or indirectly during the hydrogenolysis process [41,42] . Besides the main pathway, the side products such as MTHFA and DMTHF were observed in these cases, which is responsible for the unwanted furan ring hydrogenation of the corresponding intermediate and DMF [43] . Combining the discussed results and other reported literatures [44,45] , we hypothesize that through the hydrogenation of −CHO in HMF, followed by the hydrogenolysis of the −OH groups in BHMF, HMF could be converted into DMF via MFA intermediate [7] .…”

Hydroconversion of 5‐Hydroxymethylfurfural to 2,5‐Dimethylfuran and 2,5‐Dimethyltetrahydrofuran over Non‐promoted Ni/SBA‐15

“…Since emphasis was early put on the need for an auxiliary metal or for surface acidic sites to obtain a selective catalyst, the catalytic properties of monometallic catalysts based on non‐noble metals have been paradoxically less explored . Ni‐based catalysts are known for their hydrogenation ability, but successes in the selective conversion of HMF have mostly been achieved with bimetallic or multifunctional catalysts, e. g ., Ni‐W 2 C/C, Ni−Fe/CNTs (carbon nanotubes), Ni/LaFeO 3 and others …”

“…[12,13] Nibased catalysts are known for their hydrogenation ability, [14] but successes in the selective conversion of HMF have mostly been achieved with bimetallic or multifunctional catalysts, e. g., Ni-W 2 C/C, NiÀ Fe/CNTs (carbon nanotubes), Ni/LaFeO 3 and others. [15][16][17][18] Kong et al have published a series of papers in which the reactivity of monometallic Ni catalysts was investigated. [14,[19][20] Raney Ni was shown to be active in the hydrogenation of the aldehyde function and of the furan ring of HMF to BHMTHF at 100°C in dioxane, while hydrogenation and hydrogenolysis of the side-groups to DMF was favored at a higher temperature of 180°C.…”

Synthesis of jet fuel additive with cyclopentanone

“…With the increase of social concern about the energy and environmental problems, the catalytic conversion of renewable, CO 2 neutral and inedible biomass to high quality fuels [1][2][3][4][5][6][7][8][9][10][11][12][13] and value-added chemicals [14][15][16][17][18][19][20][21][22][23][24][25][26] has become a very hot topic. Jet fuel is one of the most demanded liquid transportation fuels.…”
