Formation of oil shale sludge mainly occurs in the retorting process in which a large amount of shale dust contained in the retorting gas and vapor is absorbed by fine shale oil mist to generate a sort of oleophilic
substance, which then goes through a violent agitation to transform into colloidal semisolid material, i.

Hydrophobic Oil-Capturing Water Permeable Drag-Net," William Redvers Belisle (New Orleans, Louisiana, USA).
They have good hydrophobic and oleophilic
properties, but their non-biodegradability is a major disadvantage (Wei et al, 2003).
They are naturally oleophilic
but can be treated to increase wettability.
Rival teams have applied nanotechnology to the problem to produce ultra-lightweight sponges that are oleophilic
and hydrophobic -- they love oil but repel water.
To improve the dispersion of LCB in aqueous solution, LCB was pretreated by means of SDBS, by which SDBS was adsorbed onto the surface or into pores of LCB, and the hydrophilic and oleophilic
features of MLCB were improved.
Lead author Daniel Hashim, a graduate student in the Rice lab of materials scientist Pulickel Ajayan, said the blocks are both superhydrophobic (they hate water, so they float really well) and oleophilic
(they love oil).
Before treatment, the purchased common cast iron substrate is hydrophilic and oleophilic
because the water and oil contact angles are 50 [+ or -] 1.
Printing areas are oleophilic
and hydrophobic, they attract ink and repel water, while non-printing areas are completely different--hydrophilic and oleophobic, attract water and repel ink.
3] which enables them to adsorb water-based fountain solution, while printing areas are built from oleophilic
and hydrophobic photoactive layer which in the printing process adsorbes oil-based printing ink.
The oil lubricates between the oleophilic
silica (treated silica) and the rubber matrix, and between the rubber-rubber chains (ref.
