Slurries of water-saturated coal and liquid hydrocarbon carriers having the properties of low apparent viscosity, controlled sedimentation and easy separation, which properties render the slurries transportable over long distances in conventional oil pipelines to predetermined destinations where they are easily separated into their constituent parts, are prepared by combining coal with a liquid hydrocarbon carrier, a minor amount of water in excess of the amount in the water-saturated coal and, optionally, a surfactant to form a mixture and then agitating the mixture under high shear conditions to form agglomerated coal particles in which water acts as a coordinator bridging layer around and/or among the agglomerated particles.
A mixture of carbonaceous solids and a liquid hydrocarbon carrier, said mixture being easily separable and having controlled sedimentation properties which render it suitable for transport through a pipeline and the subsequent separation of said solids from said carrier, which mixture comprises:
A mixture of coal and a liquid hydrocarbon carrier having an apparent viscosity of less than about 300 centipoises at 40.degree. F., said mixture being easily separable and having controlled sedimentation properties which render it suitable for transportation through a pipeline and the subsequent separation of said coal from said carrier, which mixture is made by the process comprising:
A process for making a mixture of carbonaceous solids and a liquid hydrocarbon carrier, said mixture being suitable for transportation through a pipeline and the subsequent separation of said solids from said carrier, which process comprises:
A process for preparing a mixture of coal and a liquid hydrocarbon carrier, transporting said mixture through a pipeline, and subsequently separating said coal from said liquid hydrocarbon carrier, which process comprises:
A process for making a mixture of coal and a liquid hydrocarbon carrier, said mixture being suitable for transportation through a pipeline and the subsequent separation of said coal from said carrier, which process comprises:
