Abstract
The present invention provides a system for producing mesophase coke from an isotropic pitch. The system includes a reactor having a first heating zone to carry out pretreating of the isotropic pitch by operating at a temperature of 250° C.-350° C. under atmospheric pressure. The reactor further includes a second heating zone to carry out heating of the pretreated isotropic pitch by maintaining the temperature of 350° C.-500° C. under the atmospheric pressure to obtain mesophase pitch. The reactor includes a third heating zone to carry out heating of the said mesophase pitch by maintaining the temperature of 500° C.-800° C. under the atmospheric pressure to obtain mesophase coke. The system further includes a pusher unit adapted to physically move the container from the entry zone to the exit zone to obtain the mesophase coke.
