| titleOfInvention | Rare earth Ｙ-zeolite-containing hydrocarbon cracking catalyst and preparation method thereof |
| abstract | The present invention discloses a rare earth Y-zeolite containing catalyst for hydrocarbon cracking and a process for producing the same. The catalyst of the present invention has a rare earth content in the crystal lattice of the rare earth Y-zeolite, in terms of RE 2 O 3 , 4 to 15% by weight, an initial unit cell size of 2.440 to 2.465 nm, and 100 at 800 ° C. for 17 hours. The equilibrium unit cell size after the% steam-aging treatment is larger than 2.435 nm. The catalyst is prepared in the following steps: first, the rare earth Y-zeolite is dried until the moisture content is less than 10% by weight, and then dried in a state in which the weight ratio of SiCl 4 : Y-zeolite is 0.1∼0.9: 1. Reacting with SiCl 4 gas carried by air, purging with dry air and then washing with cation removal water to remove water soluble byproducts; Mixing the obtained rare earth Y-zeolite with a binder and clay, pulping and shaping by spray drying. The zeolite content of the catalyst of the present invention is reduced by 5-25% by weight compared to the catalyst conventionally prepared for heavy oil cracking, reducing the olefin content. The catalyst not only has good cracking activity, high hydrothermal stability, high heavy oil conversion and good selectivity for gasoline, dry gas, coke and the like, but also has the characteristic of effectively reducing the olefin content of the gasoline produced.n n n n Rare earth Y-zeolites, catalysts, hydrocarbon cracking, olefin content, hydrothermal stability, pseudoboehmite |
