Developing 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 کاملAdsorption 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 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 کاملUltrasonic Assisted Adsorption of Basic Dyes from Binary Component Systems onto ZnO Nanoparticles Loaded on Activated Carbon Derived from Almond Shell: Optimization by Central Composite Design
In this study, ZnO nanoparticles were loaded on activated carbon prepared from almond shell (ZnO-NP-AC). Then, this novel material applied as an efficient adsorbent for the ultrasonic assisted simultaneous removal of Basic Blue 41(BB41) and Basic Red 46 (BR46) in binary solution. The efficiency of proposed activated carbon was enhanced by acid treatment and subsequent modification by physical ...
متن کاملStudy of Hexane Adsorption on Activated Carbons with Differences in Their Surface Chemistry.
The study of aliphatic compounds adsorption on activated carbon can be carried out from the energetic change involved in the interaction; the energy values can be determined from isotherms or by the immersion enthalpy. Vapor phase adsorption isotherms of hexane at 263 K on five activated carbons with different content of oxygenated groups and the immersion enthalpy of the activated carbons in h...
