<p>Herein disclosed is a method for coal liquefaction comprising: supersaturating a hydrocarbonaceous liquid stream in a high shear device with a gas stream comprising hydrogen and optionally one or more C1-C6 hydrocarbons to form a supersaturated dispersion; and contacting the supersaturated dispersion with coal in the high shear device or in a coal liquefaction reactor to generate a product stream. In some embodiments, the method further comprises utilizing a conversion catalyst, wherein the catalyst is provided as a slurry, a fluidized bed, or a fixed bed. In some embodiments, the method further comprises feeding a conversion catalyst into the high shear device. In some embodiments, the method further comprises recycling at least a portion of an off gas from the reactor, recycling at least a portion of the product stream from the reactor, or both. Herein also disclosed is a system for coal liquefaction.</p> |
