“…% (referred to LA), and the catalyst was mainly deactivated by leaching of sulphonic sites. Pd/ZSM-5 also demonstrated an excellent performance, with high VA and EV yields (92 %) after an 8 h reaction using ethanol as solvent 9 . Recently, it has also been reported that the metal selected can modulate the selectivity of LA into GVL or valeric biofuels using 1,4 dioxane as solvent.…”

“…The influence of different acidic supports of Pd‐based catalysts on catalytic performance in the conversion of LA to VA and its esters was discussed by Muñoz‐Olasagasti et al . Amorphous SiO 2 −Al 2 O 3 and several commercial zeolites were used as the supports; Pd/ZSM‐5 showed the best performance, with high VA and EV yields of 92 % in total (Table , entry 5).…”

Valerate esters (VAEs) commonly derived from levulinic acid (LA), which is deemed as one of the most promising biomass platform molecules, have been hailed as “valeric biofuels” in recent years. The cascade transformation of LA to VAEs consists of a series of acid‐ and metal‐catalyzed processes alternately, in which heterogeneous bifunctional catalysts are required for better catalytic performance. The transformation pathway from LA to VAEs is presented, and bifunctional catalytic systems for the cascade transformation of LA into valeric acid (VA) and its esters, as well as one‐pot conversion processes, are reviewed. Additionally, effects of metal and acid sites on the catalytic performance are discussed in detail. Impacts of and improvements to coke deposition, which is determined to be the primary reason for the reduction in catalytic activity, are also analyzed. Finally, feasible suggestions are proposed for enhanced catalytic performance and a reduction in overall costs.

Цеолиты получили широкое распространение в качестве индивидуальных катализаторов в различных органических реакциях [10,11], а также как носители для наночастиц благородных и неблагородных металлов.…”

В работе проводилось исследование рутений-содержащей каталитической системы на основе цеолита ZSM-5 в реакции гидрирования левулиновой кислоты (ЛК) до гамма-валеролактона (ГВЛ). Было изучено влияние температуры и давления на скорость трансформации ЛК, а также стабильность каталитической системы Ru/HZSM-5. Показано, что применение Ru/HZSM-5 позволяет в достаточно мягких условиях (температура 100С, парциальное давление водорода 1 МПа) достичь 98% конверсии ЛК за 60 мин реакции. In this work, ruthenium-containing catalytic system based on zeolite ZSM-5 was studied in the reaction of levulinic acid (LA) hydrogenation to gamma-valerolactone (GVL). The influence of temperature and pressure on the rate of LA transformation, as well as the stability of Ru/HZSM-5 catalytic system, was studied. It was shown that the use of Ru/HZSM-5 allows achieving 98% of LA conversion in 60 minutes of the reaction under relatively mild conditions (temperature 100°C, partial hydrogen pressure 1 MPa).
