A lumped kinetic model for hydrotreating 850+ /sup 0/F coal extract is proposed in this study. This model distinguishes hydrogenation and cracking reactions that occur in the catalytic hydrotreating of coal extract. The reaction rates of aged Shell 324M Ni/Mo catalyst used to hydrotreat Illinois No. 6 coal extract were determined. Using these results, the effects of temperature and space rate on the 850+ /sup 0/F conversion, as well as donor hydrogen content, were investigated. In addition, the effects of feed properties and catalyst aging on the hydrotreating performance were illustrated.
