The aim of this project is to develop a methodology to predict, from a knowledge of feed and catalyst properties, effectiveness factors for catalytic hydroprocessing of coal and coal liquids. To achieve this aim, it is necessary to account for restrictive diffusion, which has not hitherto been done from a fundamental approach under reaction conditions. The research entails a study of hydrodenitrogenation of model compounds and coal-derived liquids using three NiMo/alumina catalysts of different pore size to develop, for restrictive diffusion, a relationship that can be used for estimating reliable effectiveness factors. The research program includes: Task A - measurement of pertinent properties of the catalysts and of several coal liquids; Task B - determination of effective diffusivities and turtuosities of the catalysts; Task C - development of restrictive diffusion correlations from data on model N-compound reactions; Task D - testing of correlations with coal-liquid cuts and whole coal-liquid feed. Results are presented and discussed from Tasks B and D. 9 refs., 6 figs., 4 tabs.
