Embodiments of the present disclosure are directed to hydrocracking catalysts and methods of making same. The hydrocracking catalyst comprises a platinum encapsulated zeolite having a crystallinity greater than 20% determined by X-ray powder diffraction analysis.

Proposed inventions are a recipe of denitrification-oxidation complex catalyst containing an SCR catalyst and an oxidation catalyst to simultaneously remove nitrogen oxides, carbon monoxide, hydrocarbons, and ammonia, a manufacturing method thereof, an exhaust gas treatment method using the denitrification-oxidation complex catalyst, and an SCR denitrification system including the denitrification-oxidation complex catalyst. The denitrification-oxidation complex catalyst simultaneously removes nitrogen oxides, carbon monoxide, hydrocarbons, and ammonia and exhibits an increased catalytic effect compared to the cases where the denitrification catalyst used alone and the denitrification and the oxidation catalyst ratios are and not properly balanced. When the denitrification-oxidation complex catalyst is applied to an SCR denitrification system, the structure is simplified, space is saved, cost is reduced, and catalyst maintenance is easy.

Provided is a Fluid Catalytic Cracking catalyst additive composition and method of making the same. The catalyst additive composition comprises zeolite about 35 wt% to about 80 wt%, preferably about 40 wt% to about 70 wt%; silica about 0 wt% to about 10 wt%, preferably about 2 wt% to about 10 wt%; about 10.5 wt% to 20 wt% alumina and about 7 wt% to 20 wt% P.sub.2O.sub.5, preferably about 11 wt% to about 18 wt%, and the balance clay which can fall between 0 and 50 wt%. The alumina is typically derived from more than one source, such as at least an amorphous or small crystallite size pseudo-boehmite alumina and then either a either a large crystallite size alumina or other reactive alumina.

A supported catalyst for decomposing an organic substance that includes a carrier and catalyst particles supported on the carrier. The catalyst particles contain a perovskite-type composite oxide represented by A.sub.xB.sub.yM.sub.zO.sub.w, where A contains at least one of Ba and Sr, B contains Zr, M is at least one of Mn, Co, Ni, and Fe, y+z=1, x>1, z<0.4, and w is a positive value that satisfies electrical neutrality. An organic substance decomposition rate after the supported catalyst is subjected to a heat treatment at 950° C. for 48 hours is greater than 0.97 when the organic substance decomposition rate before the heat treatment is regarded as 1, and an amount of the catalyst particles peeled off when the supported catalyst is ultrasonicated in water at 28 kHz and 220 W for 15 minutes is less than 1 wt % of the catalyst particles before untrasonication.

A layered catalyst reactor system and process for hydrotreatment of hydrocarbon feedstocks. The layered catalyst system reactors comprise vertical bed layers including a demetallization catalyst layer, multiple layers of supported hydrotreating catalyst layer, and multiple alternating layers of supported hydrocracking catalysts and self-supported hydrotreating catalysts. The arrangement of the catalyst layers mitigates the risk of temperature run-aways, with improvements in hydrotreatment performance.
