Abstract
A self-lubricating fuel composition is provided formed from powdered coal, a hydrocarbon fraction, water, a surfactant and a strong electrolyte. This composition develops a lubricating layer between the mechanical parts in relative movement with respect to the fluid and the fluid. Such self lubrication causes a reduction of the friction and consequently of the pressure losses during transport in ducts.
