“…Considering these results, the B APF was selected for the hydrogenation tests shown in Table 5.B APF reduction was performed at H 2 pressure of 1.25 MPa and 90 °C, using a monometallic ruthenium catalyst, Ru/C, and a ruthenium‐tin bimetallic catalyst, RuSn 0.4 /C. The systems selected in this work have been previously studied in the aqueous phase hydrogenation of commercial furfural [49,50] . These catalysts proved to be active, selective and stable in this reaction, without leaching of the metallic phase into the reaction medium.…”

“…In this work, it is of particular interest the production of alcohols, furfuryl alcohol and tetrahydrofurfuryl alcohol, from the selective hydrogenation of bio‐furans. Previous research of our group has demonstrated that tin‐modified ruthenium supported catalysts are very effective for the selective reduction of the carbonyl group of furfural in the aqueous phase [49,50] . These results are promising for the application of these catalysts in the treatment of substrates rich in water, such as crude bioliquids [47] .…”

“…Biofurans such as furfural and 5-hydroxymethylfurfural (FUR and 5-HMF) can be transformed through different catalytic routes into products of high industrial interest. [47,48] In this sense, catalytic hydrogenations are revealed as high potential pathways [42,[49][50][51][52] being furfuryl alcohol, tetrahydrofurfuryl alcohol, dimethyl tetrahydrofuran and methyl tetrahydrofuran some of the reduced derivatives of interest.

The production of added value products following catalytic hydrogenation reactions of bioliquids was studied. These bioliquids were obtained from the pyrolysis of raw and acidtreated (H 3 PO 4 ) Tall Fescue (Fescue arundinacea) waste. Before the pyrolytic test, the biomass samples were analyzed by a micro thermogravimetric analysis coupled with FTIR spectroscopy (TGA-IR), which enables the chemical identification of functional groups of gaseous molecules originated by solid/gas transformations. From these results, the pyrolysis temperature was selected, and bench scale pyrolysis reactions were carried out. The pyrolysis bioliquids showed high furfural concentration, 46 and 70 % for fescue and acid washed fescue, respectively. The bioliquid with the highest furfural concentration was catalytically hydrogenated in aqueous phase. A batch reactor was employed, with Ru/C and RuÀ Sn/C catalysts to produce high added value alcohols.

γ‐Valerolactone (GVL) can be obtained by efficient hydrogenation of levulinic acid using ruthenium‐based catalysts in an aqueous medium. This paper reports an in‐depth study on the activity and selectivity of Ru catalysts supported on zirconia‐alumina, focusing on the effect of Ru concentration (0.5, 1.5 and 3 wt.% of Ru) and the selection of operational reaction variables. The results showed that the activity strongly depends on the number and oxidation state of the supported ruthenium particles. The most active catalyst, Ru3/ZA, presented the highest number of nanometric particles of zerovalent Ru and the highest number of acid sites. This catalyst gave ca. 100% selectivity towards GVL, at high conversion of levulinic acid (over 99%) under the best operating conditions evaluated (120°C, 3 MPa H2 pressure, 1 h of reaction, and 0.1 g of catalyst). In addition, this catalyst kept high levels of conversion and selectivity after successive reuse cycles.

Furfuryl alcohol, which is the hydrogenated product of furfural, has been identified as a very promising platform chemical with high potential for applications in the manufacture of key chemicals, lubricants, fragrances, and pharmaceuticals. In this work, bare SB, and x % Ru/Al‐SB (x=1.5, 2.5, 3.5, and 4.5 wt. %) samples were fabricated by a hydrothermal method. Bare and most active catalysts were characterized by different techniques, such as BET, FE‐SEM, TEM, FT‐IR, and XRD, to understand their physical and chemical properties. An evaluation of the effects of various reaction parameters, such as catalyst loading, reaction temperature, and reaction time, on the catalytic performance, showed higher catalytic conversion of furfural and selectivity for the desired products. The most active RuS3 catalyst showed 100 % conversion of furfural and 99 % selectivity for furfuryl alcohol. It could be reused for five consecutive reaction cycles without significant loss of performance. In addition, Ru leaching and loss of conversion or selectivity were not noticed during the five‐run recycling test. The EDS elemental mapping analysis of the used catalyst established the preservation of the mesoporous structure, suggesting a strong interaction between the hexagonal porous silicate and the Ru nanoparticles.
