Summary
An extensive literature survey has been conducted on the kinetics of hydrotreatment of coal derived liquids and shale oils. The relevant articles are classified under hydrotreatment kinetics, hydrotreatment studies, model compound kinetics, and model compound studies. A bibliographic listing of these articles is given at the end of this report. Only the articles listed under hydrotreatment kinetics were subjected to a systematic summary and are presented in this report. The following conclusions can be drawn from this survey: (a) The number of actual hydrotreatment kinetic studies is very limited. (b) Batch and continuous flow packed-bed reactors have usually been used in kinetic studies, but no comparable results for two types of reactors can be found. (c) The kinetic models that have been developed or tested on coal or shale liquids have been almost entirely simple n-th order models. Predominantly the first order system is favored, and especially for the narrow boiling range liquids. The wide boiling range liquids require higher order or modified models. (d) No generalized model could be obtained from this survey for representing the hydrotreating kinetics of generic classes of coal or shale liquids. (e) The temperature effect is correlated by the Arrhenius equation. The data fit has not always resulted in constant preexponential factors or activation energies. The discrepancies have been attributed to a change in reaction mechanisms. (f) Hydrogen pressure has been shown to be a significant parameter especially at low pressures. (g) Co-Mo and Ni-Mo catalysts have commonly been used, and apparently the type of catalyst has little or no effect on the kinetic model. (h) No definite conclusions can be made for the kinetic models of HDS, HDN and HDO. Often a first order model has been used to correlate the kinetic data. 17 references.
