Fixed-bed adsorption column design
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 ... Web(22) The fixed-bed adsorption breakthrough apparatus used is shown in Figure 1; its properties are listed in Table 1. The center of a roughly 51 cm long × 5.08 cm outer diameter tube was used to house a packed bed of adsorbent 25.4 cm in height. The remainder of the column was packed with glass beads.
