The paper d&Is with the ‘formaion oyf emulsion’f;el;‘and their evaluation as boiler fuels. The results of this evaluation show that the emulsion fuels are compatible with the corresponding fuel oil. The prepared emulsion fuels were fuel oil-water emulsions with calorific values of 33.9-42.3 MJkg-’ and fuel oil-water-charcoal emulsions with calorific values of 30.637.8 MJkg.‘. These emulsion fuels have relatively low sulphur and wax contents, undergo the water gas shift reaction during combustion and make use of solid charcoal. The results also show that the presence of surfactants in the emulsion fuels acts as an inhibitor of the c&rosion activity of the water and fuel oil.

The higher stirring speed of 1300 rpm at 450 Ae, 90 min, and 13 MPa gave a higher oil yield above 70% based on daf coal due to the better dispersion of the NiMosupported KB catalyst of fine particles. 96104814 Rheologlcal water-coal suspenslons

For coal liquefaction using dispersed MO sulphide catalyst from either water-soluble or oil-soluble precursors, the addition of water can dramatitally improve coal conversion at temperatures that are much lower than those used in conventional processes. Some important factors affecting water-promoted cataytic conversion include H,O-coal ratio, coal rank, and temperature.
