Abstract A phosphonus-contained cracking catalyst for hydrocarbons is prepared from Y molecular sieve or Y molecular sieve and MFI molecular sieve and/or beta molecular sieve (10-60 wt.%), clay (0-75), dual-alumina adhesive (10-60), P and rare-earth through treating molecular sieve with P-contained solution, mixing molecular sieves and then with clay and said adhesive, calcining at 500 deg.C or spray drying, and treating with P-contained solution. It can reduce the olefin content in gasoline fraction to 20-26 wt.%.
