PREVENTION OF DELETERIOUS DEPOSITSIN A COAL LIQUEFACTION SYSTEMAbstract of the DisclosureA process for preventing the formation of dele-terious coke deposits on the walls of coal liquefactionreactor vessels involves passing hydrogen and a feedslurry comprising feed coal and recycle liquid solventto a coal liquefaction reaction zone while imparting acritical mixing energy of at least 3500 ergs per cubiccentimeter of reaction zone volume per second to thereacting slurry.
