DEFINITION
Classification: 44/280
SOLID CARBONACEOUS FUEL DISPERSED IN A LIQUID MEDIUM (E.G.,DISPERSED COAL, COKE, CARBON POWDER, PEAT, ETC.):
(under the class definition) Compositions wherein a liquid medium acts as dispersant for a solid carbonaceous fuel.
(1) Note. Asphalt and asphaltenes are considered to be mineral oil substances, even if solid. Class 208, particularly subclasses 15+, provides for fuel compositions which are mixtures having mineral oil components only.
(2) Note. Examples of compositions provided for herein are aqueous coal slurries to which has been added a surfactant.
(3) Note. Included in the solid carbonaceous fuels encompassed are coal, charcoal, lignite, wood, coke, peat, carbon black, carbon powder, shale, solid asphalt, solid asphaltene, and solid bitumen.
