“…The ). It was noted that the greater (k YN ) magnitude was obtained when both the initial MG dye concentration and flow rate were higher, but the magnitude decreased with the greater bed height, and the same results were observed by [51]. In addition, the (τ) value decreased with an increase in the flow rate and initial concentration of the MG dye, but increased when the height of bed was increased due to the increase of the MG initial concentration increased the rivalry among the dye molecules for the adsorption location, which eventually yielded a greater rate of uptake [52].…”

In this study, a Methyl Green (MG) dye pollutant was separated by Mobil Composition Matter No. 41 (MCM-41) in a fixed-bed continuous column with investigated three parameters, namely a bed height (2-6 cm), initial MG concentration (10-30 mgL -1 ) and a process flow rate (0.8-1.6 mL min À1 ). Results indicated that the highest bed capacity of 20.97 mg/g was obtained with respective to optimal values such as; 6 cm for a column height, 0.8 mL min À1 for flow rate, and an initial MG concentration 20 mgL -1 . Furthermore, a quantity of the adsorbed pollutant decreased as the flow rate increased, while increasing the initial MG concentration yielded the opposite effect. The column apparatus was performed properly at the low flow rate, whereas both the breakthrough and exhaustion time increased with the bed depth. Thomas and Yoon-Nelson models were applied for predicting the breakthrough curves and calculating the characteristic factors of the laboratory fixed-bed adsorption column, which were beneficial for process design. Based on regression coefficient analyses, results of employing the Yoon-Nelson model was found to be superior to the Thomas one. Breakthrough performance indicated that MCM-41 was suitable for applications in continuous adsorption regimes for MG dye. The mesoporous MCM-41 was recovered effectively by calcinations and employed again for four times in the continuous system successfully.

Ion exchange resins (IER) possess a catalytically flexible structure which enables them to be easily applied for renewable energy production and environmentally friendly reactions. More specifically, they can be used as catalyst or catalyst support in other industrialized processes such as; esterification, transesterification and hydrogenation reactions. Several works on esterification, transesterification and hydrogenation reactions are in literature. This study reviews some of these works which includes the utilization of IER in esterification, trans-esterification and hydrogenation reactions. Recent reports show that IER are conventionally used as catalyst in esterification and transesterification reactions. For hydrogenation reactions, IER have been utilized as support for metallic catalyst, raising questions on their inability to be applied as catalyst. Hence, this study has itemized these various reactions, detailing their applications which are highly industrialized reaction processes.
