WebApr 10, 2024 · Fixed-bed column adsorption tests 2.3.1. Lab-scale column. Lab-scale adsorption tests were conducted in a cylindric column made of polyethylene of 2.3 cm internal diameter (D) and 50 cm length. The influence of bed height Z (14, 24, and 34 cm) and flow rate Q (10, 20, 30 mL/min) were analyzed with an initial concentration of Mn (II) … Webters, i.e. length-diameter ratio of bed and column diameter to particle diameter ratio mentioned by Wang at al. and Inglezakis [13]; [14]. Simulation of sulfur adsorption, in the liquid phase, on a fixed bed, has been reported in a few studies. The scope of the present study was relat-ed to mathematical adsorption modeling in a packed bed with ...
