The overall objective of this project is to develop a fundamental understanding of the reactions occurring at the onset of coke formation during the co-processing of coals with petroleum residua. Specific objectives include examination of chemical components, or groups of components, in coals and petroleum feedstocks to quantify and rank the effects of these components in retarding or enhancement of coke formation. The work involves bench scale reactions in microautoclaves, supplemented by studies of the carbonaceous residues by such techniques as diffuse reflectance Fourier transform infrared spectroscopy and {sup 13}C nuclear magnetic resonance spectrometry. This quarter microautoclave testing of mixtures of model compounds and coal was concluded. In addition mixtures of coals and petroleum feedstocks were reacted under the same reaction conditions as used for the model compounds experiments. The petroleum resids were also independently tested in absence of coal. For a set of coal/resid feedstock pairs tests were performed in both horizontal and vertical microautoclaves in order to compare the mixing properties of these two different designs. 7 refs., 25 figs.
