Activated carbon

Synthesis and Application of Granular Activated Carbon from Biomass Waste Materials for Water Treatment

There is an increased global demand for activated carbon (AC) in application of water treatment and purification. Water pollutants that have exhibited a greater removal efficiency by AC included but not limited to heavy metals, pharmaceuticals, pesticides, natural organic matter, disinfection by-products, and microplastics. Granular activated carbon (GAC) is mostly used in aqueous solutions and adsorption columns for water treatment. Commercial AC is not only costly, but also obtained from...

Optimization of heavy metal removal by activated carbon obtained as a co-product from fast pyrolysis of rice husks

The realization of a circular economy calls for maximum utilization of existing resources with no recoverable waste after the process cycle. During fast pyrolysis of biomass to produce bio-oil for energy purposes, solid residues in form of bio-char are generated. In this study, residual char after pyrolytic-oil extraction from rice husks was activated using steam at 800 °C to produce activated carbon (AC). The formed AC was characterized and evaluated...
