    • A catalyst and a method for selectively reducing nitrogen oxides ('''NOx'') with ammonia are provided. The catalyst includes a first component comprising a zeolite or mixture of zeolites selected from the group consisting of ZSM-5, ZSM-I l, ZSM-12, ZSM-18, ZSM-23, MCM-zeolites, mordenite, faujasite, ferrierite, zeolite beta, and mixtures thereof; a second component comprising at least one member selected from the group consisting of cerium, iron, copper, gallium, manganese, chromium, cobalt, molybdenum, tin, rhenium, tantalum, osmium, barium, boron, calcium, strontium, potassium, vanadium, nickel, tungsten, an actinide, mixtures of actinides, a lanthanide, mixtures of lanthanides, and mixtures thereof; optionally an oxygen storage material and optionally an inorganic oxide. The catalyst selectively reduces nitrogen oxides to nitrogen with ammonia at high temperatures. The catalyst has high hydrothermal stability. The catalyst has high activity for conversion of low levels of nitrogen oxides in exhaust streams. The catalyst and the method may have special application to selective reduction of nitrogen oxides in exhaust gas from gas turbines and gas engines, although the catalyst and the method have broad application to a wide range of gas streams that have excess oxygen and high temperatures. The temperature of exhaust gas from gas turbines and gas engines is high. Both the high temperature and the low levels of inlet NOx are challenging for selective catalytic reduction (SCR) catalysts.
    • 提供了一种用氨选择还原氮氧化物(“NO x”)的催化剂和方法。 催化剂包括第一组分,其包含选自ZSM-5,ZSM-11,ZSM-12,ZSM-18,ZSM-23,MCM-沸石,丝光沸石,八面沸石,镁碱沸石的沸石或沸石混合物, 沸石β及其混合物; 包含选自铈,铁,铜,镓,锰,铬,钴,钼,锡,铼,钽,锇,钡,硼,钙,锶,钾,钒中的至少一种的第二组分, 镍,钨,锕系元素,锕系元素的混合物,镧系元素,镧系元素的混合物及其混合物; 任选的储氧材料和任选的无机氧化物。 该催化剂在高温下用氨选择性还原氮氧化物至氮气。 该催化剂具有很高的水热稳定性。 该催化剂具有高的活性,用于转化废气流中低含量的氮氧化物。 催化剂和方法可能特别适用于选择性还原来自燃气轮机和燃气发动机的废气中的氮氧化物,尽管催化剂和方法广泛应用于具有过量氧气和高温的大范围气流。 燃气轮机和燃气发动机的废气温度高。 入口NOx的高温和低水平都是选择性催化还原(SCR)催化剂的挑战。

    • A thin film for reflection films or semi-transparent reflection films which comprises a matrix comprising silver or a silver alloy and, dispersed therein, a compound phase comprising at least one of the nitrides, oxides, composite oxides, nitroxides, carbides, sulfides, chlorides, silicides, fluorides, borides, hydrides, phosphides, selenides, and tellurides of dysprosium, gadolinium, erbium, praseodymium, samarium, lanthanum, and yttrium. This thin film may further contain, dispersed therein, at least one of the nitrides, oxides, composite oxides, nitroxides, carbides, sulfides, chlorides, silicides, fluorides, borides, hydrides, phosphides, selenides, and tellurides of silver and/or of gallium, palladium, and copper, besides the dysprosium and other compounds. The thin film is less apt to decrease in reflectance even in long-term use and can prolong the life of various apparatuses employing a reflection film, such as optical recording media and displays. The thin film is usable also as a semi-reflective/semi-transparent film for optical recording media.
    • 一种用于反射膜或半透明反射膜的薄膜,其包含由银或银合金构成的基体,并分散在其中,包含氮化物,氧化物,复合氧化物,氮氧化物,碳化物,硫化物,氯化物中的至少一种的化合物相 ,硅化物,氟化物,硼化物,氢化物,磷化物,硒化物和镝,钆,铒,镨,钐,镧和钇的碲化物。 该薄膜还可以分散在其中的至少一种氮化物,氧化物,复合氧化物,氮氧化物,碳化物,硫化物,氯化物,硅化物,氟化物,硼化物,氢化物,磷化物,硒化物和银的碲化物和/ 镓,钯和铜,除了镝等化合物。 即使在长期使用中,薄膜的反射率也不易降低,并且可以延长使用诸如光学记录介质和显示器的反射膜的各种装置的寿命。 薄膜也可用作光记录介质的半反射/半透明膜。
