In order to utilize petroleum resources efficiently and greenly,and solve the problems of high coke yield,highsulfur coke utilization,and environmental protection concerns in China’s refineries,a resid contact cracking and coke gasification integrated technology is being developed by the Research Institute of Petroleum Processing(RIPP).Based on the three technical characteristics including thin films cracking,partial oxidation,and rapid cracking,this technology not only can reduce the production rate of coke and dry gas formed during the process,but also can increase the liquid yield.Moreover,the in-situ low-temperature gasification technology is used to solve the clean utilization of high-sulfur petroleum coke,which can play the role of“Utility Island”and is a green and low-carbon technology for low-quality heavy oil upgrading.
