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