A simple kinetic model, including a first-order catalyst deactivation rate, is applied to upgrading of coal-derived feedstocks prepared from two solvent refined coal fractions. A catalyst deactivation mechanism is proposed which involves the adsorption and surface reaction of coke precursors on catalytic active sites. The effect of feedstock composition, temperature, and pressure on kinetic parameters, and in particular, the catalyst deactivation rate, is determined.
