Parallelly Aligned, Activated Carbon Coated Plates Operating as Adsorption Columns for Removing VOCs

Removing Undesirable Vocs from Biogases Using the Electrochemical Swing Adsorption onto Activated Carbon Fiber Cloths

Introduction The development of alternative and renewable energies is one of the crucial opportunities exhibited by governments to remediate the diminishing resources of the fossil feedstock. Biogases collected from landfill, digester and wastewater plants constitute a large and disposable supply to produce a rich methane stream, though these resources remain mostly unused. The biogas should be...

Adsorption capacity of activated carbon for n-alkane VOCs

The volatile organic compounds (VOCs) in the indoor air come from many sources including building materials, furnishings, occupant activities and in some cases, the ventilation air. Granular activated carbons (GAC) have been increasingly used to remove these contaminants, particularly for small commercial buildings and those located in urban centers or near industrial plants where the quality o...

Comparison of Adsorption Characteristics for VOCs on Activated Carbon and Oxidized Activated Carbon

In this investigation, the selected activated carbon is treated in NaOH solution or gas fluid with ozone from an ozone generator. FTIR, BET specific surface area and element analysis instruments were used to identify the difference in the chemical and physical characteristics between the activated carbon and oxidized activated carbon. The system of adsorption apparatus consists of a fixed adsor...

Hydrogen Adsorption on Activated Carbon

The adsorption of hydrogen on carbon nanotubes and activated carbons has generated considerable interest in relation to hydrogen storage for fuel cells applications[1-3]. However, the widespread use of hydrogen as a fuel is limited by the lack of a convenient and cost-effective method of hydrogen storage. Adsorption of supercritical hydrogen is limited by the low interaction energy between hydr...
