Enhanced recovery of platform chemicals from bio-oil via multistage liquid-liquid extraction: Solvent selection and separation mechanism
The current study used groundnut shell biomass to produce bio-oil using a micro-scale pyrolysis gas chromatography-mass spectrometry (PY-GCMS) and a semi-pilot rotary kiln system. The micro-scale study was employed to understand the impact of temperature on the chemical composition of condensable volatiles. The bio-oil chemical composition was determined using GC-MS. Based on the identified chemical components in the bio-oil, multistage liquid-liquid extraction was conducted using different organic solvents (hexane, ethyl acetate, toluene, and chloroform) to separate the major chemical groups. Results revealed that the predominant chemical groups in the bio-oil were phenolics, ketones, and aromatics. A plausible interaction mechanism between the organic solvents and the chemical groups was proposed. This study provides a basis for selecting appropriate organic solvents for the selective extraction of specific chemical groups.
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.
