Abstract
PURPOSE: To effect a high-yield, short-period, high-quality pitch production by treatment under specific condition of tar pitch obtained from thermal cracking stock oil using ACR thermal cracking process.
CONSTITUTION: Thermal cracking stock oil which contains heavy oil with b.p. 350°C or more, and from which asphalt, S, metals, and N are removed is subjected to ACR thermal cracking with adiabatic decomposition at 700W1000°C thereby providing ethylene-contg. gas, light tar, heavy tar, and quench oil. The light tar, heavy tar, and quench oil are mixed to provide a 20W80wt% of pitch content, then introduced into a extratubular heating type heater 13, and treated at 450W550°C, under pressure of 50W150kg/cm2G, for 1W15min. Then, the mixture is introduced into a soaker 14 having stirrer 17 and treated at 350W450°C, under pressure of 0.5W10kg/cm2G, for 15minW1hr. The mixture is next supplied into the softening point adjustment tank 18, where it is adjusted to a desired softening point, and discharged from the pipe 19.
