Abstract

The development of green and efficient biomass pretreatment methods is of great significance for the conversion of lignocellulosic biomass into biofuels. The main objective of this work is to demonstrate a novel recyclable CuFeO₂ catalytic pretreatment way that can be used to promote the production of bioethanol and bio-jet fuel from corncob. Compared to untreated corncob, the biomass pretreated with CuFeO₂ catalyst showed higher sugar production (39.9 %) and higher ethanol production (35.6 %). Especially, the directional transformation of corncob to bio-jet fuel has been achieved by integrating biomass fermentation and catalytic synthesis process. The ethanol conversion of 94.3 % and jet fuel selectivity of 64.7 % were obtained in the process of biofuel synthesis. Based on biomass characterizations, catalyst characterizations and reactive oxygen species analysis, the possible role and mechanism of the CuFeO₂ catalytic pretreatment were outlined. The CuFeO₂ catalytic pr-treatment can be carried out by using the recyclable catalyst at atmospheric pressure and room temperature, which may provide a useful pretreatment way for promoting the biofuel production from lignocellulosic biomass.

期刊介绍： Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials. The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy. Key areas covered by the journal: • Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation. • Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal. • Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes • Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation • Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
