Abstract

A catalytic cracking agent has an active component consisting of a phosphorus-modified molecular sieve and a non-phosphorus-modified molecular sieve or only consisting of a phosphorus-modified molecular sieve. According to an electron probe microanalysis (EPMA), the D value of phosphorus in the catalytic cracking agent is ≥65%, preferably ≥68%, provided that the active component consists of the phosphorus-modified molecular sieve and the non-phosphorus-modified molecular sieve, or the D value of phosphorus in the catalytic cracking agent is ≥82%, preferably ≥84%, provided that the active component only consists of the phosphorus-modified molecular sieve.
