摘要
Catalytic pyrolysis process(CPP)producing ethylene and propylene from paraffin base atmospheric residue was developed by RIPP and its first in the world unit was put into commercial operation successfully.The results of performance test showed that the yield of ethylene and propylene reached 14.84% and 22.21% ,respectively,at a reaction temperature of610℃by using Daqing atmospheric residue as the feedstock under an operation mode of producing ethylene and propylene at the same time,and the aromatic content of cracked naphtha reached 82.46% .The successful operation of this unit has opened a novel route for producing light olefins and aromatics from heavy oil,which is also a good example symbolizing the integration of refining technology with petrochemical process.
