    摘要： Methods and systems are provided for selective catalytic reduction of NOx with a low molecular low molecular weight hydrocarbon, e.g., propylene, as a reductant using a catalyst system including two catalysts. An exhaust stream containing an amount of NOx from a combustion operation is provided. A portion of the exhaust stream and a reductant stream including a low molecular weight hydrocarbon is introduced to a first catalytic reactor, which comprises a first catalyst including alumina loaded with silver. The NOx-reduced exhaust stream from the first catalyst is then directed to a second catalyst including zirconia loaded with at least one metal.

    摘要： A catalytic hydrocracking process for use in refining various petroleum based feedstocks to lighter hydrocarbons. The hydrocracking process for treatment of petroleum fractions utilizes a catalyst comprising (a) a layered metal oxide of the titanometallate type intercalated with an interspathic polymeric chalcogenide, e.g., polymeric silica, (b) a transition hydrogenation metal selected from Group IVA, VIA, and VIIIA of the Periodic Table such as platinum and the like, and optionally, (c) a conventional cracking component, e.g., a large pore crystalline silicate component.

    摘要： Emissions of nitrogen oxides (NO.sub.X) to the atmosphere are reduced by treatment of gases containing nitrogen oxides with a reducing agent such as ammonia in the presence of a catalyst containing a mesoporous crystalline catalyst. The mesoporous crystalline catalyst comprises an inorganic, non-layered, porous, crystalline phase aluminosilicate material which exhibits a benzene adsorption capacity of greater than about 15 grams benzene per 100 grams at 50 torr and 25.degree. C. In its preferred catalytic form, the crystalline material has a uniform, hexagonal arrangement of pores with diameters of at least about 13 .ANG. and exhibiting, after calcination, an X-ray diffraction pattern with at least on d-spacing greater than about 18 .ANG. and a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 .ANG. which corresponds to at least one peak in the X-ray diffraction pattern.

    摘要： Emission of noxious nitrogen oxides with the flue gas from the regenerator of a fluid catalytic cracking plant are reduced by incorporating into the circulating inventory of cracking catalyst separate additive particles that contain a copper-loaded zeolite material having a characteristic structure with a defined X-ray diffraction pattern. The preferred material of this type is zeolite MCM-22. The copper may be exchanged onto the zeolite or impregnated into the catalyst. In addition, the catalyst may include titanium or zirconium to provide stability and further improvements in stability may be obtained with the addition of rareearth metal cations, especially cerium or yttrium. NOX and CO emissions from the regenerator are reduced, and the gasoline produced in the unit may have an improved octane number.
