“…For instance, Luo et al reported a negative effect on activity for the hydrogenation of LA in dioxane using a Ru/H-ZSM-5 catalyst [37]. The formation of highly mobile RuO x species during the calcination step and subsequent sintering, was mentioned as the most likely reason.…”

“…Four different Ni catalysts were prepared via wet impregnation, incipient wetness impregnation, precipitation and flame spray pyrolysis, leading to different textural and, as a result, catalytic properties with wet impregnation giving the best results. Another example concerns the hydrogenation of LA to pentanoic acid using Ru supported on H-ZSM-5 [37], for which the use of Ru(NH 3 ) 6 Cl 3 as precursor resulted in much better yields than when using RuCl 3 .…”

New Frontiers in the Catalytic Synthesis of Levulinic Acid: From Sugars to Raw and Waste Biomass as Starting Feedstock

Levulinic acid (LA) is one of the top bio-based platform molecules that can be converted into many valuable chemicals. It can be produced by acid catalysis from renewable resources, such as sugars, lignocellulosic biomass and waste materials, attractive candidates due to their abundance and environmentally benign nature. The LA transition from niche product to mass-produced chemical, however, requires its production from sustainable biomass feedstocks at low costs, adopting environment-friendly techniques. This review is an up-to-date discussion of the literature on the several catalytic systems that have been developed to produce LA from the different substrates. Special attention has been paid to the recent advancements on starting materials, moving from simple sugars to raw and waste biomasses. This aspect is of paramount importance from a sustainability point of view, transforming wastes needing to be disposed into starting materials for value-added products. This review also discusses the strategies to exploit the solid residues always obtained in the LA production processes, in order to attain a circular economy approach.

“…The selectivity to GVL was around 60% for Ru/H-Beta-12.5 and around 50% for Ru/H-ZSM-5. More recently, the same group investigated the influence of the ZSM-5 cation form (H + versus NH 4 + ), Si/Al ratio and Ru precursor on metal dispersion and acidity on product yields in LA hydrogenation [27]. The best results in terms of GVL one-pot synthesis of GVL from fructose using trifluoroacetic acid (TFA) and Ru/C as the catalysts [33].…”

Support Screening Studies on the Hydrogenation of Levulinic Acid to γ-Valerolactone in Water Using Ru Catalysts

γ-Valerolactone (GVL) has been identified as a sustainable platform chemical for the production of carbon-based chemicals. Here we report a screening study on the hydrogenation of levulinic acid (LA) to GVL in water using a wide range of ruthenium supported catalysts in a batch set-up (1 wt. % Ru, 90 • C, 45 bar of H 2 , 2 wt. % catalyst on LA). Eight monometallic catalysts were tested on carbon based(C, carbon nanotubes (CNT)) and inorganic supports (Al 2 O 3 , SiO 2 , TiO 2 , ZrO 2 , Nb 2 O 5 and Beta-12.5). The best result was found for Ru/Beta-12.5 with almost quantitative LA conversion (94%) and 66% of GVL yield after 2 h reaction. The remaining product was 4-hydroxypentanoic acid (4-HPA). Catalytic activity for a bimetallic RuPd/TiO 2 catalyst was by far lower than for the monometallic Ru catalyst (9% conversion after 2 h). The effects of relevant catalyst properties (average Ru nanoparticle size, Brunauer-Emmett-Teller (BET) surface area, micropore area and total acidity) on catalyst activity were assessed.
