|a 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. 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. This quarter, a number of aspects of diffusivity at room temperature were studied. First, a method was developed for estimating the bulk diffusivity of polyaromatic compounds from extrapolation of both experimental data on related compounds and of well-accepted correlations. A tortuosity of 1.3 was determined from measured effective diffusivities for three different solutes using three different sized NiMo catalysts. A series of experimental batch runs on hydrogenation of Ni-tetraphenyl porphyrin in mesitylene and decalin solvents were carried out a 750 psig and temperatures of 300 and 350/degree/C with the NiMo catalysts. 4 refs., 6 figs., 5 tabs.
