摘要：

Coking due to possible cracking reactions in a Ni-Mo/Al2O3 hydrotreatment catalyst was studied independently of the sulfur present. A model has been tested to predict the carbon concentration profiles obtained during the reaction. Simulated and experimental results are compared and several kinetic equations are tested in the simulation. The model predicts well the average carbon level in the catalytic bed and gives a slightly higher maximum carbon concentration. (C) 2001 Elsevier Science B.V. All rights reserved.
