COAL HYDROGENATION PROCESS HAVING INCREASED SOLIDS RETENTION IN EBULLATED BED REACTOR

摘要

In e.g. the catalytic hydrogenation of coal, the concentration of unconverted coal solids in the reactor is increased by use of a coal solids deflecting means such as a baffle 30 located in the upper portion of the reactor upstream of the effluent stream withdrawal conduit opening. The solids deflection means preferably comprises a solid baffle attached to the reactor effluent withdrawal conduit upstream of its opening, and is preferably made removable from the reactor upper end.
