Buoyant particles of materials such as peat, sawdust or minerals are coated with carbon formed by heating hydrocarbons on the particles and are used to agglomerate oil on the surface of waters.ALSO:Particles of materials with a specific gravity less than water such as peat, sawdust or minerals, are coated with a hydrophobic and oleophilic carbon surface by coating with hydrocarbons, such as petroleum fractions, and heating. |
