Study on preparation of new solid fuel and its combustion performance from bio-oil and waste cooking oil mixture via vacuum distillation
The mixture of bio-oil and waste cooking oil with long carbon-chain was used to produce bio-coal via vacuum distillation, so as to improve its physicochemical properties especially its combustion performance as a new solid fuel. The effect of ratio of meat or vegetable oil represented by lard and soybean oil in the mixture (L-Oil and S-Oil) on the physical and chemical properties of bio-coal was studied emphatically. The results revealed that the bio-coal obtained via vacuum distillation of bio-oil mixed with 40 % S-oil (SBC) including more carbon content and fatty acid presented better physicochemical properties than that of bio-coal obtained by mixing L-oil (LBC) with higher carbon content (82.74 %) and calorific value (34.19 MJ/kg) basically similar to that of the commercial coal. The above bio-coal and anthracite were mixed to investigate their combustion characteristics. The TG analysis revealed that there is a synergistic effect in the combustion of the mixed bio-coal and anthracite, and the combustion temperature range of bio-coal are lower than that of anthracite. Further mixing of bio-coal was helpful to improve the flame stability and reduce the ignition temperature. Kissen-Akahira-Sunose (KAS), Flynn-WallOzawa (FWO) and Starink were used for the kinetic analysis, and the statistical R2 factors of the three methods were greater than 0.973, which reflected the high reliability of the calculation methods, and proved that the kinetics of the process are significantly influenced by the calorific rate. Overall, the high-valued utilization of bio-oil and food waste was realized in this study to produce a sustainable fuel.
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.
