To develop novel biorefinery concepts, the use of bio-based catalysts and solvents must be aligned with the principles of green chemistry. In this context, biogenic 2,5-furandicarboxylic acid (FDCA) is a very promising yet underused molecule with high potential for application as an acid catalyst, combining feasibility and sustainability with efficient and straightforward recovery. In this study, FDCA was evaluated as a catalyst in the recently developed OrganoCat pretreatment, a biphasic lignocellulose fractionation system. The catalyst was investigated for the efficient fractionation of the three main components-lignin, cellulose and noncellulosic sugars-with particular focus on the lignin quality, on the effect on enzymatic hydrolysis of the cellulosic residue, and on the noncellulosic sugar extraction. To address recovery of FDCA from the OrganoCat system, a method was developed, leading to the recovery of >97 % of FDCA with a spectroscopic purity of >99 %, maintaining full activity in consecutive runs.

“…As an important raw material for the production of long-chain hydrocarbons, methanol and other clean transportation fuels and chemicals, syngas has received extensive attention. 126–129 In addition to gasification reactions via coal and biomass, 130 the reforming reaction is one of the main routes to prepare syngas, 131 such as steam methane reforming, 132 DRM, 133–135 steam reforming of ethanol (SRG), 136 biomass steam reforming, 137–142 and the coupling of several of them (also called Bi-reforming (BRM) or the triple reforming reaction (TRM)) and so on. The coupling of these reforming reactions has several advantages, such as adjusting the H 2 /CO ratio, improving the catalyst's carbon resistance, and improving energy efficiency.…”

“…Bio‐oils, produced by fast pyrolysis of biomass, emerged as a second‐generation renewable energy carrier and potential resource for replacing fossil fuels. However, due to the high oxygen components (up to 45 wt% O), instability, and immiscibility with conventional fuels, the direct usage of bio‐oils with a low calorific value is not feasible and they must be up‐graded to meet the necessities of the current infrastructure ,,. In this regard, elimination of oxygen from the pyrolytic bio‐oils is the key parameter for production of bio fuels.…”

Design of Efficient Noble Metal Free Copper‐Promoted Nickel‐Ceria‐Zirconia Nanocatalyst for Bio‐Fuel Upgrading

A new series of noble metal free bimetallic Cu−Ni supported ceria‐zirconia catalysts (Cu−Ni/CZ) has been developed with various Cu/Ni ratios by a simple co‐precipitation/impregnation method. Aqueous‐phase hydrodeoxygenation (HDO) of vanillin a typical compound of lignin‐derived bio‐oil, in promoting biomass refining was carried out to investigate catalytic performances under 25 bar of H2 pressure at 160oC. All the as‐synthesized catalysts were thoroughly characterised employing powder XRD, Raman spectroscopy, H2‐TPR, HR‐TEM, HAADF‐STEM, EDS Mapping, and XPS. It was found that 15 wt% Cu on Ni/CZ (Cu−Ni/CZ−B) nanocomposite enhanced activity significantly in comparison with other bimetallic or monometallic catalysts, exhibiting ∼98% of vanillin conversion and ∼94% of selectivity toward 2‐methoxy‐4‐methylphenol as a desired product. The Cu−Ni/CZ−B catalyst shows ∼4‐fold increase in activity compared with Cu−Ni/CeO2 and Cu−Ni/ZrO2, the mono oxide supported counterparts. The superior catalytic performance with improved stability were explained by synergistic effects at the interfaces of each species, in which electron interactions between Ni, Cu, and ceria‐zirconia support generated novel active sites. XRD and HR‐TEM revealed that Cu−Ni bimetallic phases were created on the ceria‐zirconia, which were responsible for enhancement of catalytic performance with no significant drop in catalytic activity with desired product selectivity for eleven successive catalytic cycles demonstrating the excellent stability and reproducibility of this catalyst system.
