The possibility to use glycerol carbonate (GlyC) as an innovative alkylating agent for phenolic compounds in solventless conditions and the presence of a catalytic amount both homogeneous heterogeneous bases is herein described. In particular, peculiar, polyfunctional structure GlyC allows one obtain formation not only mono-phenoxy-1,2-propanediol (MPP) analogue but also 1,3-diphenoxy-2-propanol (DPP), latter being elusive using more traditional, toxic, carcinogenic reagents such glycidol...
This paper reports on a systematic study the catalytic gas-phase synthesis of methyl methacrylate (MMA) by means hydroxymethylation and dehydration propionate (MP) with formaldehyde (FAL), latter being produced in situ methanol (MeOH) dehydrogenation. represents promising variant current industrial Alpha process which pure FAL is fed, alongside MP, into fixed-bed reactor filled supported Cs2O catalyst. In this way, an alternative avoiding need to feed carcinogenic has been developed feeding...
Levulinic acid derivatives, such as alkyl levulinates, are suitable starting reactants for the production of fuel components, namely γ-valerolactone (GVL), valerates, pentanol, and pentylvalerate (PV).
Green chemistry is part of the chemical industry’s response to calls for improved environmental responsibility. It also one several paths redemption from its erstwhile infamous reputation as most polluting sectors. We studied impacts implementing some these principles on production methyl methacrylate (MMA), monomer PMMA popularly known acrylic glass. This study used life cycle assessment (LCA) methodology compare potential three different approaches MMA. Two are established industrial...
In recent years, the upgrading of lignocellulose bio-oils from fast-pyrolysis by means ketonization has emerged as a frontier research domain to produce new generation biofuels. Propionic acid (PA) is extensively investigated model reaction over metal oxides, but activity other materials, such phosphates, mostly unknown. Therefore, PA was preliminarily in gas phase both phosphates and oxides Al, Zr, La. Their catalytic correlated physicochemical properties materials characterized XRD, XRF,...
Green hydrogen introduction in hard-to-abate processes is held back by the cost of substituting steam reforming plants with electrolyzers. However, green can be integrated properly modified processes. The process proposed here involves substitution oxy-reforming, which coupling former catalytic partial oxidation (CPO), exploiting pure oxygen coproduced during electrolysis to feed CPO, allows for better heat exchange thanks its exothermic nature. With aim developing tailored catalysts...
In this study, alkali metal-doped sepiolite based catalysts were developed for the up-grading of ethanol through Guerbet reaction mechanism. The prepared by wetness impregnation with aqueous solution containing metal precursors salts over calcined sepiolite, and finally activated at 500ºC in air. have been characterized XRD, SEM-EDS, TGA-DSC, N2-adsorption. addition, TPD-CO2 TPD-NH3 used to determine acid basic characteristics catalysts. tested into a quartz continuous gas-flow system...
Continuous-flow, gas-phase cross-ketonization of alkyl 2-furoates with bio-based acids toward an alternative, selective production valuable acyl furan intermediates.
Continuous-flow, gas-phase selective oxidative dehydrogenation (ODH) of unsaturated long chain alcohols ( i.e. decen-1-ol isomers) to the corresponding aldehydes over an innovative, highly dispersed Cu-based catalyst supported ferrite.
The transformation of 1-butanol into either butenes or maleic anhydride was carried out both with and without oxygen, using V/P/O catalysts. With vanadyl pyrophosphate prepared by coprecipitation, at temperature lower than 240 °C selectivity to higher 90%, but a slow deactivation took place. At 300 in the presence air, phthalic anhydrides were prevailing products, 60% 14%, respectively. Catalytic performance affected crystallinity acidity. αI-VOPO4 showed poor absence quick due coke...
Molecular ruthenium cyclopentadienone complexes were employed for the first time as pre-catalysts in homogeneously catalysed Aqueous Phase Reforming (APR) of glucose. Shvo's complex resulted best pre-catalyst (loading 2 mol %) with H2 yields up to 28.9 % at 150 °C. Studies final mixture allowed identify catalyst's resting state a mononuclear dicarbonyl extracted organic fraction. In situ NMR experiments and HPLC analyses on aqueous fraction gave awareness presence sorbitol, fructose,...
Abstract Laboratory‐prepared Gnp using molten salt, commercial and reduced graphene oxide (rGO) have been characterized utilized as support for CO 2 hydrogenation catalysts. Ni− Ru− catalysts supported over Gnp, rGO deeply at different stages Raman, IR, XRD, FE‐SEM‐EDXS, SEM‐EDXS, XPS, TEM, also addressing carbon loss before reaction evolved species, thus allowing a better comprehension of the produced materials. Ni Ru/rGO were inactive while Gnp‐supported ones active. Ru has found almost...
The Cover Feature shows graphene nanoplatelets (Gnp) as catalyst support for Ni or Ru and their use in CO2 hydrogenation. prepared heterogeneous is deeply characterized by assessing catalytic performances, quantifying particle size sulfur content, evaluating carbon loss during pre-reduction. Ru-based almost complete selectivity towards the reverse water gas shift reaction (rWGS), while Ni-based also produces methane (methanation). More information can be found Research Article G.

Bioethanol upgrading has been identified as a valuable approach to develop circular economy for fuels and chemicals production. Herein, the gas-phase, continuous-flow catalytic of ethanol blends with features suitable jet fuel is tackled through an innovative strategy based on promotion several reactions in cascade.
