Qualitative Investigation of Petroleum Coke Production Condition

Petroleum coke is produced by thermal cracking of vacuum distillation residue is in the form of raw and calcined coke. Most of calcined coke consumed in aluminum industry. Feed properties such as conradson carbon residue and operating conditions such as pressure and temperature is affected the quality and quantity of petroleum cokes. In this paper, one of the Iranian refinery vacuum distillation residue was performed under delayed coking conditions in the pressures of 1 and 4 bar and temperatures of 420oC and 520oC to investigate the effect of operating conditions on the yield and sulfur content of coke. Increasing the reaction temperature at a given reaction pressure led to decrease the yield and sulfur content of coke. Increasing the reaction pressure at a given reaction temperature led to higher yields of coke and as well as a decrease in the sulfur content of coke. So, the high pressure and optimum temperature will be good to production of petroleum cokes.
