| titleOfInvention | MFI structure molecular sieve of a kind of phosphorous and transition metal and preparation method thereof |
| abstract | MFI structure molecular sieve of a kind of phosphorous and transition metal and preparation method thereof, in the MFI structure molecular sieve of described phosphorous and transition metal, the distribution D of phosphorus meets 0≤D≤0.8, D=P (S)/P (C), P (S) represents that the zeolite crystal adopting TEM-EDX method to characterize is from edge to the phosphorus content of 1/5th of center, P (C) represents the phosphorus content of zeolite crystal center, and its infrared spectrum obtained as probe with trimethylpyridine is at 1633cmn -1 place is without absorption peak.The preparation method of described molecular sieve, comprising: mix with silicon source by baked phosphorous and MFI structure molecular sieve that is transition metal, in 145 ~ 190 DEG C of reaction crystallization 2 ~ 80 hours, and then separation, drying, roasting at 400 ~ 800 DEG C.This molecular sieve is used for catalytic cracking, and productivity of low carbon olefin hydrocarbon is high, and coke, hydrogen and dry gas yied reduce. |
