Hydrogenation of 2,4-dinitrotoluene using a Pd/A1_2O_3 catalyst in a slurry reactor: A molecular level approach to kinetic modeling and nonisothermal effects

摘要

The kinetics of hydrogenation of 2,4-dinitrotoluene (2,4DNT) using a 5/100 Pd/Al_2O_3 catalyst was studied in a semibatch slurry reactor in a temperature range of 323-363 K. Experimental data on the concentration-time and H_2 consumption-time profiles were obtained, and the effects of 2,4-DNT noncentration, H_2 pressure, and catalyst loading were studied under both isothermal and nonisothermal conditions.
