    摘要： The present invention relates to a polyurethane ballast layer, the method for preparing the same and a railway comprising the polyurethane ballast layer. The polyurethane ballast layer provided in this invention comprises a polyurethane-filled ballast layer and a polyurethane external protective layer, wherein the polyurethane-filled ballast layer comprises ballasts and polyurethane foam filled in the space among the ballasts. The polyurethane ballast layer provided in this invention can reduce the probability of ballast crashing, shifting and cracking under heavy load, and separate the ballast track from the outside environment to prevent rain, snow and wastes from entering into the internal space of the ballast track bed. Furthermore, the polyurethane ballast layer can keep the polyurethane foam filled in the ballasts layer away from water in the outside environment to avoid hydrolysis. The polyurethane ballast layer presented in this invention can be used in the railway ballast track bed to extend the track bed maintenance cycle, and save maintenance cost significantly.

    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： The present invention relates to a heavy oil catalytic cracking catalyst and preparation method thereof. The catalyst comprises 2 to 50% by weight of an ultra-stable rare earth type Y molecular sieve, 0.5 to 30% by weight of one or more other molecular sieves, 0.5 to 70% by weight of clay, 1.0 to 65% by weight of high-temperature-resistant inorganic oxides, and 0.01 to 12.5% by weight of rare earth oxide. The ultra-stable rare earth type Y molecular sieve is obtained as follows: the raw material, NaY molecular sieve, is subjected to a rare earth exchange and a dispersing pre-exchange, and the molecular sieve slurry is filtered, washed and subjected to a first calcination to produce a “one-exchange one-calcination” rare earth sodium Y molecular sieve, wherein the order of the rare earth exchange and the dispersing pre-exchange is not limited; and the “one-exchange one-calcination” rare earth sodium Y molecular sieve is further subjected to ammonium salt exchange for sodium reduction and a second calcination. The catalyst provided in the present invention is characteristic in its high heavy-oil-conversion capacity, a high total liquid yield and a high light oil yield.
