Fluorescence microscopy has commonly been employed in coal and kerogen characterization, but has not been widely used in liquefaction process development research. This study applies existing quantitative fluorescence microscopical techniques to non-

The trend of vitrinite fluorescence intensity within the bituminous rank range, peaking in high volatile A coals, is thought to be due mainly to the development of the mobile or molecular phase with thermal maturation. A strong parallelism exists bet
A goal of this work was to reduce the cost associated with hydrogen ion reagent `A`. Microautoclave tests were previously conducted using `A`/dry coal = 1.0. This quarter test were completed using a ratio of 2.0. Conversion was poor at the low ratio.

Work this quarter concentrated on evaluating the effects of low- severity, first stage reaction conditions on coal conversions, exploring the effect of solvent-to-coal ratio on filtration performance, exploring the effects of pretreatment on disperse

Dry catalytic hydrogenation, using an impregnated molybdenum catalyst, has been used to explore the processes of coal liquefaction and their relation to coal structure. It was found that for high activity the molybdenum must be present as MoS 2 and t

Carbonization studies of petroleum vacuum distillation residua have been carried out on a laboratory scale with the objective of developing a better understanding of the causes and mechanisms of the incidence of shot coke formation in delayed coking.
