Abstract
Abstract A PROCESS FOR PRODUCING NEEDLE-LIKE COAL PITCH COKE BY DELAYED COKING METHOD CHARACTERIZED BY STEPS OF REMOVING QUINOLINE-INSOLUBLE MATTER FROM THE COAL PITCH, HEATING SAID PITCH AT A TEMPERATURE ABOVE 450* C., INTRODUCING THE HEATED PITCH INTO A COKING REACTOR AT A SURFACE VELOCITY TONS/HR./M.2 OF CROSS SECTION OF THE COKING REACTOR) LESS THAN THE VALUE OF (TO-450)/34.D, WHEREIN TO REPRESENTS TEMPERATURE (* C.) OF THE STARTING PITCH AT THE INLET OF THE COKING REACTOR AND D REPRESENTS RATIO BY WEIGHT OF DISTILLATE LIGHTER THAN 400* C. IN THE STARTING PITCH, AND MAINTAINING THE AVERAGE TEMPERATURE IN THE REACTOR AT A TEMPERATURE ABOVE 400* C. FOR AT LEAST 20 HOURS, WHILE LIGHT OIL AND OTHER MINOR COMPONENTS WHICH DO NOT TAKE PART IN THE REACTION ARE WITHDRAWN FROM THE TOP OF THE REACTOR.
