Abstract
Efficient management of renewable energy sources is crucial for sustainable economic development and reducing carbon footprint. The use of biomass agricultural residues through thermochemical conversion processes, such as gasification, offers a promising solution by producing eco-friendly fuels and chemicals. Biomass properties, type of gasifier and its operating conditions have important roles on the quality and characteristics of gasification products. Entrained flow gasifiers (EFR) and droptube furnaces (DTF) represent popular technologies that can operate at higher temperatures with various feedstock types. They are easy to scale up and commercially available. However, the released syngas may contain impurities like polycyclic aromatic hydrocarbons and soot, impacting the syngas cleaning system and equipment performance. Therefore, the understanding of biomass gasification at a laboratory scale is a preliminary step in evaluating its relevance for industrial applications, for which EFR and DTF can provide extremely useful information. The present manuscript reviews experimental works on biomass gasification in these types of reactors and discusses the effect of the operating conditions (temperature, gasifying agent, diameter, residence time and ash effect) in the current used approaches to identify the existent gaps, such as related to impurity release and handling. It was shown that the presence of ashes catalyzes the conversion of tars, inhibiting the formation of soot during biomass gasification. The retrieved information is anticipated to be useful for researchers, end users as well as energy planners.
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.
