Abstract

Abstract: The performance of LDR-100 FCC catalyst developed by Lanzhou Petrochemical Research Center of PetroChina was investigated on a riser pilot plant unit and applied in commercial FCC unit processing heavy feedstocks. The evaluation results of pilot plant riser unit showed that as compared with a commercial reference catalyst, its propylene yield increased 0.74 percentage points, the RON of its gasoline increased 0.70 units, slurry oil yield reduced 1.45 percentage points and olefin volume fraction of gasoline reduced 6.13 percentage points. Commercial application results showed that compared with based case, the total liquid yield increased 0.42 percentage points, RON of gasoline increased 3 units, the consumption of catalyst reduced from 2.24 kg/t to 1.76 kg/t, an economical benefit of 26.387 7 million RMB could be obtained annually.

Key words: catalyst, olefin, RON, prolylene, catalyst consumption, riser
