In this research hydrogenation kinetic of alpha-methylstyrene (AMS) on Pd/Al2O3
catalyst was studied. The reaction is mildly exothermic (ÄH=-109 kJ/mol). Intrinsic
kinetic law was investigated under wide range of operating conditions 0.1 and 0.2 gm
catalyst loading, 0.5-100 wt% AMS, 10, 15 and 20 bar pressure and 343-373 K
The experiment data are fitted to estimate the kinetic parameters for different reaction
mechanisms by using ACM (Aspen Custom Modeler) software. Finally the results of
produced reaction mechanisms are compared with experimental results to obtain the
optimum reaction mechanism
