Abstract: A supported catalyst has a support and a metal active component disposed on the support. The metal active component is at least one selected from the group consisting of a Group VIB metal element and a Group VIII metal element. The support contains at least one of heat-resistant inorganic oxides and molecular sieves and includes an internal channel penetrating the support. The ratio of the cross-section area of the channel to the cross-section area of the support is 0.05-3:100. The difference R between the water absorption rate and the BET pore volume of the support is not less than 0.2 mL/g. The supported catalyst can be used as a hydrogenation catalyst. When used in the hydrocracking of hydrocarbon oils, it can achieve high catalytic activity and high yield of jet fuels at the same time. The supported catalyst can also be used as a Fischer-Tropsch synthesis catalyst.

Abstract: Disclosed are a phosphorus-containing high-silica molecular sieve, its preparation and application thereof, wherein the molecular sieve comprises about 86.5-99.8 wt % of silicon, about 0.1-13.5 wt % of aluminum and about 0.01-6 wt % of phosphorus, calculated as oxides and based on the dry weight of the molecular sieve, the molecular sieve has an XRD pattern with at least three diffraction peaks, the first strong peak is present at a diffraction angle of about 5.9-6.9°, the second strong peak is present at a diffraction angle of about 10.0-11.0°, and the third strong peak is present at a diffraction angle of about 15.6-16.7°. The phosphorus-containing high-silica molecular sieve shows an improved hydrocracking activity in the presence of nitrogen-containing species when used in the preparation of hydrocracking catalysts.

Abstract: A hydrocracking catalyst comprises a support, at least one of VIII Group metal components, and at least one of VIB Group metal components. The support comprises an acidic silica-alumina component and alumina derived from a pseudo-boehmite component, wherein the content of the acidic silica-alumina component is 3-80 wt %, the content of alumina derived from the pseudo-boehmite component is 20-95 wt %, based on the support. The support is obtained by mixing, molding, drying and calcining the acidic silica-alumina component with the pseudo-boehmite component, wherein said pseudo-boehmite component comprises pseudo-boehmite PB1 and pseudo-boehmite PB2, wherein the content of PB1 is 10-90 wt % and the content of PB2 is 0-60 wt % on a dry basis and based on the support.
