Volatile matter in coke

The volatiles in coke are related to the furnace exit temperature; when the furnace exit temperature is high, the volatiles decrease while other operating conditions remain unchanged； The volatile content is related to the time of low-volume steam supply; as this time increases, the thermal cracking reaction continues at higher temperatures within the coke tower. At the same time, low-volume steam supply reduces the vapor pressure of oil and gas in the coke, facilitating their release and thus reducing the volatile content ； Large amounts of steam have little effect on the volatile components, as they cause the coke in the coke tower to cool down rapidly, thereby stopping the thermal decomposition reactions. Moreover, the heavier components in the coke, compared to the oil, cannot turn into gas and escape due to the drop in temperature; hence, large amounts of steam have a minimal impact on the volatile components ； The circulation ratio has a significant impact on the volatile content; the higher the circulation ratio, the lower the volatile content
