Adsorption of volatile organic compounds by pecan shell- and almond shell-based granular activated carbons.
The objective of this research was to determine the effectiveness of using pecan and almond shell-based granular activated carbons (GACs) in the adsorption of volatile organic compounds (VOCs) of health concern and known toxic compounds (such as bromo-dichloromethane, benzene, carbon tetrachloride, 1,1,1-trichloromethane, chloroform, and 1,1-dichloromethane) compared to the adsorption efficienc...
متن کاملDeveloping almond shell-derived activated carbons as CO2 adsorbents
Two series of carbon dioxide adsorbents were prepared from almond shells, by carbonisation followed either by activation with CO2 or by heat treatment in the presence of ammonia gas (amination). Both procedures gave carbons with high CO2 adsorption capacities in pure CO2 as well as in a binary mixture of 15 % CO2 in N2. Activation with carbon dioxide significantly developed porosity in the samp...
متن کاملActivated carbons prepared from peanut shell and sunflower seed shell for high CO2 adsorption
Biomass wastes are considered as cost-effective and sustainable precursors to prepare activated carbons for CO2 capture. In this study, two biomass-derived activated carbons were prepared using peanut shell and sunflower seed shell, and the optimal activated carbons were obtained at low KOH/carbon ratio of about 1. The peanut shell derived activated carbon (P-973-1.00) and sunflower seed shell ...
متن کاملUnderstanding Phenol Adsorption Mechanisms on Activated Carbons
The interactions between phenol molecules and activated carbons were investigated in order to understand the adsorption mechanism of this aromatic compound. A series of activated carbons with varied chemical composition but similar porous features were synthesized and submitted to phenol exposure from aqueous phase, followed by thermogravimetric analysis and identification of the desorbed speci...
متن کاملAdsorption of metal ions by pecan shell-based granular activated carbons.
The present investigation was undertaken to evaluate the adsorption effectiveness of pecan shell-based granular activated carbons (GACs) in removing metal ions (Cu(2+), Pb(2+), Zn(2+)) commonly found in municipal and industrial wastewater. Pecan shells were activated by phosphoric acid, steam or carbon dioxide activation methods. Metal ion adsorption of shell-based GACs was compared to the meta...
