Production of bioadsorbent from phosphoric acid …

High mineral (ash) content in agricultural biomass such as PKS and CS creates a significantly different challenge for preparing high-quality activated carbon. Currently, carbon from this high-ash agricultural biomass generated in thermochemical conversion has only been used as a soil amendment or low-grade fuel [ 7 , 8 ]; this inherently limits the market demand for this type of carbon.

Carbon - Compounds | Britannica

Although carbon is usually a reducing agent, under acidic conditions elemental carbon is a moderately strong oxidizing agent. The large energy of the carbon–carbon bond makes activation energy requirements for the reaction so high that direct reduction of carbon—e.g., to methane (formula CH 4 )—is impractical.

Preparation of high surface area activated carbon from …

Abstract The present study attempts to utilize Eupatorium adenophorum to prepare high surface area activated carbon (HSAAC) with K 2 CO 3 activation using microwave heating. The operational variables including microwave power, K 2 CO 3 /C mass ratio and heating time on the adsorption capability and yield were identified. Additionally, the surface characteristics of HSAAC were characterized by
