Impregnated Palm Kernel Shell Activated Carbon for CO2 Adsorption by Pressure Swing Adsorption

Biogas Upgrading by Pressure Swing Adsorption

Activated carbon fiber cloth electrothermal swing adsorption system.

Capture and recovery of hazardous air pollutants (HAPs) and volatile organic compounds (VOCs) from gas streams using physical adsorption onto activated carbon fiber cloth (ACFC) is demonstrated on the bench-scale. This system is regenerated electrothermally, by passing an electric current directly through the ACFC. The adsorbate desorbs from the ACFC, rapidly condenses on the inside walls of th...

Low pressure adsorption of CO2 on multi-wall carbon nanotubes

Volumetric techniques were employed to study the adsorption of CO2 on a purified multi-wall carbon nanotubes (MWNT’s) sample, as a mesoporous material, at isothermal conditions of 288, 293 and 298 K and pressures ranging from 30 to 150 kPa. Langmuir, Freundlich and Sips equations were used to represent the isotherms. Also the parameters of these fitted isotherm models have been determined. The ...

CO2 adsorption by activated templated carbons.

Highly porous carbons have been prepared by the chemical activation of two mesoporous carbons obtained by using hexagonal- (SBA-15) and cubic (KIT-6)-ordered mesostructured silica as hard templates. These materials were investigated as sorbents for CO(2) capture. The activation process was carried out with KOH at different temperatures in the 600-800°C range. Textural characterization of these ...

Co2 Adsorption by Surface Modified Carbon Sorbents

Anthropogenic emissions have increased the CO2 concentration on the atmosphere with over 30% compared to pre-industrialize levels [1]. Most of these anthropogenic emissions are caused by fossil fuel utilization, where around one-third is due to electricity generation from fossil fuel combustion, mainly from coal-fired units. Furthermore, fossil fuel electricity generation units rank as the firs...
