Effective conversion of biomass-derived ethyl levulinate into γ-valerolactone over commercial zeolite supported Pt catalysts

Abstract

Selective hydrogenation of biomass-derived ethyl levulinate into γ-valerolactone over commercial zeolite supported catalysts was performed, and high yield was obtained.

Advances in porous and nanoscale catalysts for viable biomass conversion

“…For the hydrogenation of ethyl levulinate, the 1% Pt/ZSM-35 catalyst provided 100% ethyl levulinate conversion and 99% g-valerolactone selectivity, outperforming Pt catalysts supported on SAPO-34, ZSM-35, ZSM-5, HY, USY, and MOR zeolites. 134 Abundant metallic Pt NPs and optimum surface acidity of ZSM-35 were the primary reasons for achieving high yields of g-valerolactone. The synergistic effect of metal sites and zeolite acid sites was also observed in Zn/ZSM-5 catalysts for the conversion of g-valerolactone to aromatic compounds.…”

Cascade catalytic hydrogenation–cyclization of methyl levulinate to form γ-valerolactone over Ru nanoparticles supported on a sulfonic acid-functionalized UiO-66 catalyst

“…1,2 In this context, biomass, an inexpensive, renewable, and widely available resource, has been recognized as a promising alternative to replace fossil fuel resources for the sustainable production of biochemicals and biofuels. 3,4 Among the various chemicals synthesized from biomass to date, gvalerolactone (GVL) has been identied as an important molecule for use as a fuel additive, a food ingredient, a renewable solvent, and an ideal intermediate for production of alkenes and other valuable chemicals due to its benign properties and versatility. [5][6][7][8][9] In addition, the upgrade of GVL to a liquid hydrocarbon fuel has also been reported, with Dumesic and coworkers designing a system that integrates the conversion of GVL to butene via decarboxylation over a silica/alumina catalyst with the subsequent oligomerization of butene over an acidic catalyst (HZSM-5 or Amberlyst 70).…”

Highly stable Ru nanoparticles incorporated in mesoporous carbon catalysts for production of γ-valerolactone

“…With the depletion of fossil resources and concern for environment, the conversion of biomass to chemicals and liquid fuels has attracted interest worldwide. γ-valerolactone (GVL), a naturally occurring chemical in fruits, is a safe and value-added product that can be widely used as liquid fuel, renewable solvent, food additives, and intermediate in the synthesis of fine chemicals [1][2][3]. In the past few years, attention was highly focused on GVL obtained by hydrogenation of levulinic acid (LA).…”
