Hydrodeoxygenation (HDO) of 5-hydroxymethylfurfural (HMF) was examined over well-defined and uniform, Pt-Ni, Pt-Zn and Pt-Cu alloyed nanocrystals (NCs) supported on carbon, at 33 bar and between 160 and 200 °C. Pt-Ni alloy catalysts were prepared in three different Pt:Ni ratios, Pt6Ni, Pt3Ni, and PtNi. While all of the Pt-Ni alloys were more selective for producing 2,5-dimethylfuran (DMF) than were Pt or Ni monometallic catalysts, the Pt3Ni catalyst was superior to the other compositions, exhibiting a yield of 98% due to its optimum surface composition. Similarly high yields were obtained on catalysts prepared from Pt2Zn and PtCu NCs. Possible reasons are given for why each of the Pt-alloy catalysts is highly selective

Metal Catalysts for the Efficient Transformation of Biomass‐derived HMF and Furfural to Value Added Chemicals

2018

View full text Add to dashboard Cite

Catalytic transformation of biomass‐derived compounds to different platform chemicals and liquid fuel is a prominent way to reduce the global dependence on fossil resources. In past few decades, biomass‐derived furans such as 2‐furfuraldehyde (furfural) and 5‐hydroxymethyl‐2‐furfural (HMF) have received outstanding attention because of their wide applications in the production of various industrially important value‐added chemicals and fuel components. Various catalytic systems and methodologies have been extensively explored for the transformation of these furans to a wide range of products including open ring diketones, ketoacids, alcohols and long chain alkanes. This Review is aimed to provide an extensive overview of the recent developments of several high‐performing heterogeneous catalysts for the catalytic upgradation of the key biomass‐derived furans (furfural and HMF) to value‐added chemicals. Moreover, the role of these catalysts in the catalytic transformations including hydrogenation, decarbonylation, oxidation, hydrogenolysis and ring opening reactions, and the mechanistic pathways are also highlighted in this Review.

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

et al. 2020

The selective hydroconversion of 5‐hydroxymethylfurfural (HMF) to biofuels is currently highly sought‐for. While the literature has demonstrated that this reaction is possible on promoted Ni catalysts, we show here that a monometallic, non‐promoted Ni/SBA‐15 catalyst, prepared by incipient wetness impregnation, can convert HMF to 2,5‐dimethylfuran (DMF) and to 2,5‐dimethyltetrahydrofuran (DMTHF) at 180 °C, in a consecutive way. Through a control over reaction time, high yields to DMF (71 %, at conversion of 93 %) or DMTHF (97 %, at conversion of 100 %) can be achieved. Kinetic modelling suggests a preferential route to DMF via 5‐methylfurfural (MFFR) as intermediate, though the route via 2,5‐bis(hydroxylmethyl)furan (BHMF) is also present. The favored route in the experimental conditions involves the hydrogenolysis of the hydroxyl group of HMF as first step, followed by the hydrogenation of the aldehyde function, to methylfurfuryl alcohol (MFOL). It is suggested a higher reaction rate of hydrogenation or hydrogenolysis of the side group is linked to the presence of a methyl group in the molecule. No hydrogenation of the furan ring is detected on the intermediates.
