The perfermance test on a commercial riser cracker shows that meta-Y-3A molecular sieve cracking catalyst is of high activity and improved gasoline selectivity.
Based on the analysis, the new concept of two-stage riser fluid catalytic cracking (TSRFCC) was proposed, and the advantage of the TSRFCC technology was analyzed.
