Abstract: The present invention relates to a method for the catalytic synthesis of lactide from lactic acid. The method relates to the synthesis of lactide from lactic acid under the catalysis of a zinc oxide nanoparticle aqueous dispersion as a catalyst. The present invention has four technical characteristics: I. the zinc oxide nanoparticle aqueous dispersion catalyst has a sufficient surface area, and the size of nanoparticles is merely 30-40 nm, providing a sufficient contact area between the substrate (lactic acid) and the catalyst; II. the new catalyst has a milder catalytic effect on polymerization, allowing the molecular weight distribution of a prepolymer within a range of 400-1500 g/mol, which is advantageous for depolymerization to proceed; III. the new catalyst is stable, thus avoiding oxidation or carbonization in a high temperature reaction; and IV. the new catalyst has a low toxicity and a small threat to human health.

Abstract: Provided herein is a hydrotreating catalyst for hydrocarbon oil having high desulfurization activity, and high abrasion strength and high compressive strength. A process for producing the hydrotreating catalyst is also provided. The hydrotreating catalyst uses an alumina-phosphorus support. The support contains 0.5 to 2.0 mass % of phosphorus in terms of an oxide. The support loads a metal in Group 6A of the periodic table, and a metal in Group 8 of the periodic table. The hydrotreating catalyst has a specific surface area of 150 m2/g or more. The hydrotreating catalyst has a total pore volume of 0.40 to 0.75 ml/g as measured by a mercury intrusion method. The hydrotreating catalyst has two maximal peaks in a pore diameter range of 6 nm to 13 nm in a log differential pore volume distribution measured by a mercury intrusion method. The hydrotreating catalyst has an abrasion strength of 0.5% or less. The hydrotreating catalyst has a compressive strength of 15 N/mm or more. The support is produced from, for example, a hydrate obtained by adding phosphorus to an alumina hydrate obtained by using two mixtures of an acidic aqueous aluminum salt solution and a basic aqueous aluminum salt solution.

Abstract: The present invention provides an 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. The molecular sieve comprises 1 to 20% by weight of rare earth oxide, not more than 1.2% by weight of sodium oxide, has a crystallinity of 51 to 69%, and a lattice parameter of 2.451 nm to 2.469 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. 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.

Abstract: In this fuel cell electrode catalyst layer, a catalyst is supported on a carrier comprising inorganic oxide particles. The fuel cell electrode catalyst layer is provided with a porous structure. When a mercury penetration method is used to measure the pore size distribution of the porous structure, a peak is observed in the range spanning from 0.005 μm to 0.1 μm inclusive, and a peak is also observed in the range spanning from over 0.1 μm to not more than 1 μm. When P1 represents the peak intensity in the range spanning from 0.005 μm to 0.1 μm inclusive, and P2 represents the peak intensity in the range spanning from over 0.1 μm to not more than 1 μm, the value of P2/P1 is 0.2-10 inclusive. It is preferable that the inorganic oxide be tin oxide.
