Conversion of levulinic acid into γ-valerolactone using Fe3(CO)12: mimicking a biorefinery setting by exploiting crude liquors from biomass acid hydrolysis.
نویسندگان
چکیده
The conversion of biomass-derived levulinic acid (LA) into gamma-valerolactone (GVL) using formic acid (FA) and Fe3(CO)12 as the catalyst precursor was achieved in 92% yield. To mimic a biorefinery setting, crude liquor (containing 20% LA) from the acid hydrolysis of sugarcane biomass in a pilot plant facility was directly converted into GVL in good yield (50%), without the need for isolating LA.

High performing and stable supported nano-alloys for the catalytic hydrogenation of levulinic acid to γ-valerolactone
The catalytic hydrogenation of levulinic acid, a key platform molecule in many biorefinery schemes, into γ-valerolactone is considered as one of the pivotal reactions to convert lignocellulose-based biomass into renewable fuels and chemicals. Here we report on the development of highly active, selective and stable supported metal catalysts for this reaction and on the beneficial effects of meta...

The current transition to a sustainable source of chemicals and energy is being driven by political, economic, and environmental concerns associated with petroleum-derived feed stocks. In this context, the conversion of lignocellulosic biomass, a renewable resource, into platform molecules and fuels has received increasing interest. In order for biomass to effectively contribute to reducing our...
متن کاملRational Synthesis to Optimize Ruthenium-based Biomass Conversion Catalysts
With worldwide petroleum resources dwindling, it is urgent to look for renewable fuels. One of major potential products from plant biomass is γ-valerolactone (GVL), which is renewable, safe to store and can be used as a liquid fuel, food additive, green solvent and an intermediate in the synthesis of many value-added chemicals. The synthesis of GVL is commonly accomplished by hydrogenation of l...
متن کاملConversion of Levulinic Acid to γ-Valerolactone over Few-Layer Graphene-Supported Ruthenium Catalysts
Few-layer graphene (FLG) supported ruthenium nanoparticle catalysts were synthesized and used for the hydrogenation of levulinic acid (LA), one of the “top 10” biomass platform molecules derived from carbohydrates. FLG-supported ruthenium catalyst showed 99.7% conversion and 100% selectivity toward γ-valerolactone (GVL) at room temperature in a batch reactor under high-pressure hydrogen. This c...
متن کاملMicrowave-Assisted γ-Valerolactone Production for Biomass Lignin Extraction: A Cascade Protocol.
The general need to slow the depletion of fossil resources and reduce carbon footprints has led to tremendous effort being invested in creating "greener" industrial processes and developing alternative means to produce fuels and synthesize platform chemicals. This work aims to design a microwave-assisted cascade process for a full biomass valorisation cycle. GVL (γ-valerolactone), a renewable g...
