Abstract
AbstractThe use of biochar produced from waste biomass is growing in popularity for addressing the most important ecological issues. Biochar is a carbon-rich by-product produced through the pyrolysis or carbonization of plant and animal biomass. Biochar (BC) shows great potential as an adsorbent in decontaminating waters. The question of the beneficial application of biochar has raised multidisciplinary research concerns in both science and engineering. Feedstock composition and type and pyrolysis conditions, such as temperature and time, significantly influence the properties of pyrolyzed biochar. Another particular application for biochar is activating its properties so as to eliminate specific contaminants. A microwave-based heating method is an alternative healing method that has been successfully used in biomass pyrolysis for biochar because of its rapid, volumetric, selective, and efficient heating. Biochar production from a wide variety of biomass sources, factors affecting its properties, biochar utilization for organic and inorganic contaminants remediation, and microwave-assisted pyrolysis (MWP) of biomass are discussed here. Along with this, the study focuses on the characteristics of biochar derived from MWP, microwave absorbers (MWAs), and catalysts applied to MWP, in addition to comparisons of biochar derived from MWP and conventional pyrolysis (CP).KeywordsBiocharProduction techniquesModification methodsMWPInorganic and organic pollutants removal
