Pellet catalyst library

Senkan and Ozturk (52) reported the synthesis and screening of a 66-member discrete heterogeneous catalyst library L7, containing Pt, Pd, and In, for the dehydrogenation of cyclohexane to benzene at 300 °C. The structure of L7 and its synthesis are reported in Fig. 11.8. Sixty-six jxrrous alumina pellets (30 mg each) were shaped into 0.3-cm-diameter, 0.1-cm-high cylinders (step a), then immersed in aqueous HCl solutions containing the 66 appropriate mixtures of InCh, PdCli, and HiPtCle (step... 

In the second example, the selective oxidation of propylene to propylene oxide (PO) was investigated with a huge library of y-alumina pellets impregnated with various single metals, binary metal combinations and catalyst loadings [40],... 

The non-linear two-point boundary value differential equation of the catalyst pellet is best solved using the orthogonal collocation method as described by Elnashaie et al. (1988a). The bulk phase initial value differential equations should be solved using standard integration routines with automatic step size to ensure accuracy (e.g. DGEAR-IMSL library).
