Reactor for solvent refined coal
An improved reactor and method for use in solvent refining of coal is described, wherein the reactor is divided into a number of compartments and has an inlet port at the bottom thereof for receiving a mixture of a solvent, coal, recycle gas and hydrogen. The compartments in the reactor are defined by a plurality of vertically spaced, perforated plates, each plate having bubble caps in the perforations thereof to permit an upflow of the feed mixture in which reactions occur as the mixture passes sequentially through the various compartments and to form vapor zones below the plates. In one embodiment, a coolant from an external source is directed into the regions below at least certain of the plates to control the reaction temperature in the zone above the plates by cooling the feed to the next sequential zone. In another embodiment, a portion of the gas below each plate is removed from the housing, cooled and then returned to the compartment above the plate to cool the reaction therein.
