Limitations of Breakthrough Curve Analysis in Fixed-Bed Adsorption

Mathematical Modeling of Fixed Bed Adsorption: Influence of Main Parameters on Breakthrough Curve

Dynamic modeling and simulation of fixed bed adsorption process was carried out by explaining the behavior of breakthrough curve parameter. Adsorption of sulfur compound, present in road fuel, has posed a great challenge. A model of fixed bed adsorption of benzothiophene from fuel was formulated with non-ideal plug flow behavior and considered velocity variation along a column. The model was so...

Removal of chlorinated volatile organic compounds by fixed bed adsorption technique: Adsorption equilibrium and breakthrough analyses

The adsorption equilibrium and dynamic breakthrough behaviour of chlorinated volatile organic compounds (CVOCs), namely chloroform and carbon tetrachloride, were experimentally investigated by using pelleted activated carbon in a fixed bed. The experimental studies were carried out at atmospheric pressure, the temperature of 313 K, the gas flow rate of 3 L/min and various inlet gas phase concen...

An Experimental Study of Adsorption Breakthrough Curves for CO2/CH4 Separation in a Fixed Bed of Nanoporous Shaped Copper Trimesate Metal Organic Framework

Copper trimesate (Cu-BTC) MOF has been pointed out as a promising adsorbent for separating carbon dioxide from methane. However, MOF’s need to be shaped prior to their use in packed bed adsorbers in order to reduce pressure drop; on the other hand, the production of mechanically resistant shaped bodies reduces their adsorption performance. In this work, Cu-BTC tablets provided by BASF are evalu...

Removal of Paracetamol on Biomass - Derived Activated 1 Carbon : Modeling the Fixed Bed Breakthrough Curves Using 2 Batch Adsorption Experiments

kinetic modeling of heavy metals adsorption on fixed bed column

the adsorption of lead (11) and copper (11) in a fixed bed column using activated carbonprepared from nipa palm nut was investigated. thomas model and yoon and nelson kinetic models were used to analyze the column performance. the rate constant for thomas model increased with increase in flow rate and initial ion concentration but remained constant at varying bed height. adsorption capacity for...
