Industrial test of refining reformed C5 oil in deep catalytic cracking unit
The industrial test of refining reformed C5 oil recycle was carried out in a 220 kt/a deep catalytic cracking(DCC)unit of Ningbo Daxie Petrochemical Co Ltd,CNOOC.The results showed that the unit ran stably during the refining process,under the condition of the outlet temperature of the riser at 620 ℃,the conversion rate of reformed C5 oil was 42.90％,of which the conversion rate of pure C5 oil was 25.65％.After refining reformed C5 oil,the ethylene volume fraction in dry gas of DCC unit in-creased by 0.55 percentage point,and the propylene yield increased by 0.12 percentage point.
