Ruthenium(iii) polyethyleneimine complexes for bifunctional ammonia production and biomass upgrading

Directional liquefaction of biomass for phenolic compounds and in situ hydrodeoxygenation upgrading of phenolics using bifunctional catalysts

Phenolic compounds derived from biomass are important feedstocks for the sustainable production of hydrocarbon biofuels. Hydrodeoxygenation is an effective process to remove oxygen-containing functionalities in phenolic compounds. This paper reported a simple method for producing hydrocarbons by liquefying biomass and upgrading liquefied products. Three phenolic compounds fractions (1#, 2#, and...

Integrated supply chain design for commodity chemicals production via woody biomass fast pyrolysis and upgrading.

This study investigates the optimal supply chain design for commodity chemicals (BTX, etc.) production via woody biomass fast pyrolysis and hydroprocessing pathway. The locations and capacities of distributed preprocessing hubs and integrated biorefinery facilities are optimized with a mixed integer linear programming model. In this integrated supply chain system, decisions on the biomass chipp...

Solvent-enabled nonenyzmatic sugar production from biomass for chemical and biological upgrading.

We recently reported a nonenzymatic biomass deconstruction process for producing carbohydrates using homogeneous mixtures of γ-valerolactone (GVL) and water as a solvent. A key step in this process is the separation of the GVL from the aqueous phase, enabling GVL recycling and the production of a concentrated aqueous carbohydrate solution. In this study, we demonstrate that phenolic solvents-se...
