SEARCH Articles Figures Tables 1 contains plots of the data obtained in n-butanol dehydration trials conducted with each of these batches of catalyst at 600 F and 1 atm. Figure PI2.8-2 contains cross plots of the smoothed data in Figure P12.8-1 that indicate the dependence of the observed rate on the diameter of the catalyst beads at conversions of 7, 14, and 21 . The experimental conditions are such that the catalyst beads are at the same temperature throughout and that there are no significant temperature gradients within the fixed bed. [Publishers Imprint]
