Experimental, Kinetics and Isotherm Modeling of Carbon Dioxide Adsorption with 13X Zeolite in a fixed bed column
In this work, zeolite 13X with porosity structure has been used as an adsorbent for adsorption of CO2 flue gas. The effect of operating conditions including pressure and time on adsorption capacity were investigated. The experiments conditions are constant temperature, the range of pressure 1 - 9 bar and the registration of adsorption capacity with passing of time. Experimental data were adjust...
متن کاملApplication of mathematical empirical models to dynamic removal of lead on natural zeolite clinoptilolite in a fixed bed column
This study examined the applicability of the mathematical empirical models by Bohart-Adams, Wolborska, Thomas and Yoon-Nelson on lead removal from aqueous solutions on a fixed bed of natural zeolite. Applicability of these models has been evaluated by fitting the experimental breakthrough curves with the curves obtained from the applied model. Experimental results have shown that the values of ...
متن کاملSustainable Treatment Method of a High Concentrated NH3 Wastewater by Using Natural Zeolite in Closed-Loop Fixed Bed Systems
The aim of this study is to investigate ammonium removal from a wastewater resulted after homogenization and anaerobic digestion of a mixture of wastes and wastewater from animal processing units and sewage sludge, by using natural zeolite clinoptilolite. Batches as well as closed loop fixed bed system (CLFB) are studied, offering an alternative to conventional fixed bed systems. The experiment...
متن کاملElimination of Cd2+ and Mn2+ from Wastewaters Using Natural Clinoptilolite and Synthetic Zeolite P
This study deals with the uptake of Cd2+ and Mn2+ ions from contaminated water using two Iranian natural clinoptilolite-rich tuffs from Meyaneh (Z-m), and Semnan (Z-s) regions , and a synthetic zeolite-P from Z-m sample (Z-P) under static (batch operation) and dynamic (column operation) conditions. To investigate the selectivity of the zeolites towar...
متن کاملAqueous Cadmium Ions Removal by Adsorption on APTMS Grafted Mesoporous Silica MCM-41 in Batch and Fixed Bed Column Processes
Highly ordered mesoporous MCM-41silica with hexagonal structure was synthesized using extracted amorphous silica from sedge (Carex riparia) ash. Obtained mesoporous materials functionalized by 3-(Aminopropyl) trimethoxysilane (APTMS) and their structures characterized by means of X-ray diffraction (XRD), nitrogen adsorption-desorption, thermogravimetric analysis (TGA) and Fourier transform infr...
