Szubiakiewicz, Elzbieta; Modelska, Magdalena; Brzezinska, Magdalena; Binczarski, Michal J.; Severino, Courtney J.; Stanishevsky, Andrei; Witonska, Izabela published the artcile< Influence of modification of supported palladium systems by polymers: PVP, AMPS and AcrAMPS on their catalytic properties in the reaction of transformation of biomass into fuel bio-components>, Synthetic Route of 97-99-4, the main research area is acidic hydrolysis waste biomass furfural reduction palladium polymer catalyst.
Catalytic systems based on highly dispersed Pd nanoparticles deposited on SiO2 modified with PVP, AMPS and AcrAMPS were prepared and used in the hydrogenation of furfural obtained by the aqueous phase acidic hydrolysis of waste biomass (sugar beet pulp, sugar beet leaves, and brewing grain) from the food industry. Pd/PVP/SiO2 catalysts containing 50 g of Pd per 1 kg of catalyst were characterized by high activity in studied process, but lower selectivity to THFA in comparison to Pd/AMPS-SiO2 or Pd/AcrAMPS-SiO2 catalysts. The modification of SiO2 by PVP followed by the palladium catalyst loading, limited the adsorption of furfural by carbonyl group which probably leads to the improvement in THFA formation, which was confirmed by FTIR studies. The physico-chem. properties of the obtained palladium catalysts were investigated by XRD, CO chemisorption, TPR H2, TG-DTA-MS and BET techniques. The ICP-AES indicated no leaching of metal into the environment during furfural reduction, which confirms the stability of the Pd/PVP/SiO2, Pd/AMPS-SiO2 and Pd/AcrAMPS-SiO2 systems in the studied process.
Fuel published new progress about Acid hydrolysis. 97-99-4 belongs to class tetrahydrofurans, and the molecular formula is C5H10O2, Synthetic Route of 97-99-4.
