The heavy oil conversion additive RCA has been put into use in FCC unit since 2013 June in Sinopec Jiujiang branch. When in a considerable amount of processing and the accounting system reserves 20%

it could increase the gasoline yield of 3% and reduced diesel yield 2%

while the dry gas

liquefied petroleum gas yield and oil slurry was varying degrees of decline

the coke yield was essentially flat. So it explanation that after RCA heavy additives added to enhance heavy oil conversion capacity of the device

and a significant increased in gasoline yield and light liquid yield. It is a significant increasing in economic efficiency.
