The slurry column is a second-generation process developed at the Idaho National Engineering Laboratory (INEL) for the beneficiation of fine (60 mesh × 10 μm) coal by a combination of the physical separation of mineral matter and the biooxidation o

An improved variant of the integral boundary-layer theory was presented in Part I of this paper for flow around axisymmetric bodies with rigid or moving surfaces in the intermediate range of Reynolds numbers. It is applied here to predict the mass tr

A new variant of integral boundary-layer theory is applied to the flow around axisymmetric fluid bodies (bubbles and drops) at Reynolds numbers of order 100. A fourth order polynomial velocity profile is matched to the inviscid flow solution at some

Millimeter-sized bubbles rise through most liquids with Reynolds numbers of several hundred. A boundary layer solution is given for flow over the upper surface of spherical or spherical-cap bubbles when surface-active solutes adsorb on the bubble int

The flood/drain reactor consists of a bed of intermediate-sized coal (roughly 0.5 to 5 mm) periodically fluidized by pumping in a mixed bacterial culture. Metabolic products and coal fines are washed out of the bed, and large pyritic inclusions and o

An optimum coal depyritization process may combine the physical removal of large liberated inclusions and the microbial degradation of the micropyrite. This was demonstrated in a 1501 aerated trough slurry reactor divided into six sections. An Illino

The effective-medium approach is used to derive expressions for the thermal conductivity of concentrated, solid-in-liquid suspensions containing varying concentrations of a third component that adsorbs on the solid surface and acts as a steric stabil

Several organic chemicals, including methane and ethanol, may be produced by the bioprocessing of coal. This may be done either by direct microbial attack on the coal, or indirectly by the bioprocessing of solubilized coal. As in chemical liquefactio
