Intrinsic Kinetic Study on Hydrogenation of 2-amylanthraquinone

The intrinsic kinetics for hydrogenation of 2-amylanthraquinone over Pd/Al2O3 commercial catalysts was studied at temperature from 313.15 to 343.15 K and hydrogen pressures from 0.1 to 0.2 MPa. The hydrogenation reaction of 2-amylanthraquinone was carried out in the mixture medium which consists of trimethylbenzene and trioctylphosphate with the volume ratio of 3:1. An exponential model was employed to describe the reaction rate, and the kinetic parameters were obtained by multivariate linear regression analysis. The results show that the reaction rate is zero order for the concentration of 2-amylanthraquinone and 0.48 order for hydrogen pressure, respectively, and the activation energy for hydrogenation is 15663 J·mol-1.
