The steps of the ammonium exchange and the phosphorus modification can be conducted continuously or non-continuously, the second calcination is conducted after the ammonium exchange for reducing sodium, the phosphorus modification can be conducted before or after the second calcination. The catalyst provided by the invention has the characteristics of high heavy oil conversion capacity, high total liquid yield, and high yield of light oil.

摘要： The present invention provides a magnesium-modified ultra-stable rare earth type Y molecular sieve and the preparation method thereof, which method is carried out by subjecting a NaY molecular sieve as the raw material to a rare earth exchange and a dispersing pre-exchange, then to an ultra-stabilization calcination treatment, and finally to a magnesium modification. The molecular sieve comprises 0.2 to 5% by weight of magnesium oxide, 1 to 20% by weight of rare earth oxide, and not more than 1.2% by weight of sodium oxide, and has a crystallinity of 46 to 63%, and a lattice parameter of 2.454 nm to 2.471 nm. In contrast to the prior art, in the molecular sieve prepared by this method, rare earth ions are located in sodalite cages, which is demonstrated by the fact that no rare earth ion is lost during the reverse exchange process. Moreover, the molecular sieve prepared by such a method has a molecular particle size D(v,0.5) of not more than 3.0 μm and a D(v,0.9) of not more than 20 μm. Such a molecular sieve has both high stability and high selectivity for the target product, while cracking catalysts using the molecular sieve as an active component is characterized by a high heavy-oil-conversion capacity and a high yield of valuable target products.

摘要： A method for preparing cracking catalyst. The method comprises making catalyst slurry having a homogeneous distribution of molecular sieve slurry, pseudoboehmite, clay, inorganic acid and aluminum-containing binder; and subsequent spray drying. Inorganic acid is added prior to the addition of pseudoboehmite; addition of molecular sieve is added after the addition of inorganic acid; and a phosphatic dispersant is added during preparation. Compared to conventional methods of preparing FCC catalyst slurry, the inventive catalyst slurry viscosity is decreased and the fluidity thereof is improved, while catalyst anti-friction is maintained. The solid content of the FCC catalyst slurry can be increased to about 40% or more. The gel forming time is significantly reduced with increased productivity and decreased catalyst production cost. Meanwhile, the catalyst has high pore volume and improved micro-reactivity. Overall reactivity performance of the catalyst is also improved.
