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.

Catalytic cracking agent containing phosphorus-modified molecular sieve, preparation process thereof, preparation system and use thereof

A phosphorus-modified MFI-structured molecular sieve is characterized in that the molecular sieve has a K value, satisfying: 70%≤K≤90%; for example, 75%≤K≤90%; further for example, 78%≤K≤85%. The K value is as defined in the specification. A cracking auxiliary or cracking catalyst contains the phosphorus-modified MFI molecular sieve.
