Abstract:
... Furfural is considered to be one of the top 30 potential chemicals derived from lignocellulosic biomass. Compared to conventional diluted acid catalysis, furfural production from lignocellulose was significantly improved by the addition of an immiscible organic solvent into the diluted acid solution. However, high conversion is usually achieved under a high water/solid ratio (>1, v/m), and the fur ...

Subject:
Cryptomeria japonica; biomass; energy efficiency; lignocellulose; particle size; renewable energy sources; saccharification; vibration
Abstract:
... Japanese cedar pulverization differences related to mill chamber size on the vibration mill with ring media (tandem ring mill) were investigated to accumulate data for scaled-up pulverization as pretreatment for enzymatic saccharification. Pulverization was conducted using tandem ring mills of three types: HV30, TR3000, and HV70. Their respective mill chamber inner diameters and interior lengths w ...

Abstract:
... Lignocellulose biorefinery produces fuel ethanol and lignin residue byproduct. The combustion ash of lignin residue after electricity generation contains high amount of phosphorous and potassium elements and the recycling to farmland provides a sustainable nutrients supply. This study demonstrated a maximum scenario of water- soluble phosphorous and potassium recycling through a dry biorefining pr ...

bioethanol; biomass; computer software; corn stover; economic feasibility; energy efficiency; fossil fuels; furfural; heat; lignocellulose; liquids; profitability; surveys
Abstract:
... In a quest of alternative energy source of fossil fuels, lignocellulosic biomass is intensively studying to produce different liquid fuels and chemicals. Both fuel (bioethanol) and chemical (furfural) were produced simultaneously in this study through two different production routes, biochemical and thermochemical route. Actually, this study firstly defined production pathway in details for each p ...
