Study on the Preparation of OilCoalWater Slurry

This paper presented a method of a new kind of triplex mixture system of oilwatercoal slurry synfuel containing gasoline, water and coal was prepared using nonionic surfactant. Tween 80 was used as emulsifying agent. The ratio of water, gasoline and coal was optimized. The optimum prescription of oilwatercoal slurry was obtained by means of orthogonal experiment.

Coal slurry impoundment SourceWatch

Coal slurry consists of solid and liquid waste and is a byproduct of the coal mining and preparation processes. It is a fine coal refuse and water. Mining generates enormous amounts of Industrial waste|solid waste in the form of rocks and dirt. This refuse is used to dam the opening of a hollow between adjacent mountains.

Interparticle Interactions in Highly Concentrated Coal ...

Coal/petcoke–water slurry viscosity is affected by interparticle interactions of the solids in water, which, in turn, is governed by the surface chemistry of the solids. To determine interparticle interactions of these carbonaceous solids in water, interfacial energies were determined on the basis of surface chemistries characterized by contact angle and ζ potential measurements.
