| titleOfInvention | A kind of phosphorus and the rare earth modified molecular sieve catalysts of ZSM 5 and its preparation method and application |
| abstract | The invention discloses a kind of phosphorus and the rare earth modified molecular sieve catalysts of ZSM 5, wherein, in the molecular sieve catalyst, the silica alumina ratio of the phosphorus and the rare earth modified molecular sieves of ZSM 5 is 50 400 to the molecular sieve catalyst：1, particle diameter is 100 500nm, and specific surface area is 160 350m 2 /g；NH 3 TPD characterized by techniques has feature adsorption peak at 170 200 DEG C.Additionally provide a kind of application of the preparation method and the catalyst of catalyst in isopropanol dehydration propylene.It just can be effectively propylene by iso-propanol conversion within the scope of relatively low temperature to use catalyst of the invention, improve the conversion ratio of isopropanol and the selectivity of propylene. |
