Parallel Chemical Activation and Surface Modification Activated Carbon for Lead Adsorption

Chemical Engineering &Technology, Volume 49, Issue 9, September 2026.
A novel parallel chemical activation and surface modification (PAM) approach was developed to produce palm kernel shell‐derived activated carbon in a simplified single‐step process. The resulting adsorbent achieved Pb2+ adsorption capacities comparable to conventionally prepared activated carbon (57.95 mg/g) while reducing adsorption costs by 36.6 ...

Oxidative Fast Pyrolysis Enabling Autothermal Production of Porous Functionalized Biochar and Anhydrosugar/Phenol‐Rich Bio‐Oil From Biomass

Carbon Energy, Volume 8, Issue 9, September 2026.
Oxidative fast pyrolysis of biomass enables autothermal production of value‐added products. ABSTRACT Oxidative fast pyrolysis can potentially overcome the heat‐supply bottleneck of conventional fast pyrolysis by enabling autothermal operation while also tailoring product quality through controlled oxygen addition.

Lead contents of coal, coal ash and fly ash

Water, Air, and Soil Pollution, 1975
Flameless atomic absorption spectrometry is applied for the determination of Pb in coal, coal ash and fly ash. Lead concentrations in coal and coal ash ranging from respectively 7 to 110 µg g−1 and 120 to 450 µg g−1 are found. A mean concentration of 1520 µg g−1 in fly ash corresponding to a concentration of 117 µg m−3 in the effluent gas suggests the ...

Retention of boron by coal ash

Environmental Science & Technology, 1982
Adsorption of boron by the hydrous oxides of aluminum, iron, and silicon appears to be the major process that controls the net release of boron from fly ash when the ash is leached at loading rates of greater than 25 g of ash/L. Coprecipitation of borate species with the hydrous oxides also contributes to the retention.
