Coal-oil slurry preparation (Patent) | DOepatents

Abstract The feasibility of substituting alcohol fermentation wastewater of maize and cassava for water to prepare coal slurries was explored. The rheological and stability properties of coal alcohol fermentation wastewater slurries were studied and compared with that of coal water slurry. The results showed that both coal maize and cassava alcohol fermentation wastewater slurries exhibited ...

Fine Coal Filtration - Peterson Filters

The rheological behaviour of coal-water slurries from two low-rank coals in South Australia has been studied as a function of solids concentration, particle size and size distribution. Coal slurries consisting of particles finer than 45 micron dispersed in water were found to exhibit a wide spectrum of flow behaviour ranging from Newtonian at low solids concentrations to shear-thinning and ...

The size consist of these products is generally in the range of 28 mesh X 0. Some Peterson Filters are used on "raw coal" applications where the filter slurry contains a large portion of coal fines nearer the 28 mesh size. However, most current day clean coal filter applications are found in "flotation" circuits.
