    摘要: A method of generating power by passing a dimethyl ether-containing fuel to a dry low NOx combustor of a fired turbine-combustor in the presence of an oxygen-containing gas for combustion in the combustor to form flue gas, and then passing the flue gas to the turbine to generate power, wherein the fuel comprises a mixture of dimethyl ether, at least one alcohol and, optionally, a component selected from the group consisting of water and C1-C6 alkanes. The fuel composition used in the inventive method permits a safe and highly efficient operation of a dry low NOx combustion system, while at the same time, minimizing the generation of NOx and carbon monoxide emissions.

    摘要: A process for manufacturing a collapsed composition is described in which the manufactured composition is substantially composed of microcrystallites collectively of the formula: ##EQU1## where M.sup.2+ is a divalent metal, M.sup.3+ is a trivalent metal, and T is vanadium, tungsten, or molybdenum. The microcrystallites are so small as to be undetectable through conventional x-ray diffraction techniques, yet high resolution electron microscopy reveals that a substantial portion of the microcrystallites are composed of a solid solution having aluminum oxide molecularly dispersed in a divalent metal monoxide crystal structure. Another portion of the microcrystallites are constituted by a spinel phase. The collapsed composition is suitable as a sulfur oxide absorbent, having comparatively high capacity and comparatively fast absorption and desorption rates, and is also suitable as a nitrogen oxide reduction catalyst. The collapsed composition may be produced by heat treating a layered mixed hydroxide clay having interlayer anions in monometalate form. The reagents for the manufacturing process are relatively salt-free, as compared to reagents utilized in previous manufacturing processes.

    摘要翻译: 描述了制造塌陷组合物的方法,其中制造的组合物基本上由以下通式组成的微晶体:M2 + 2m Al2-p Mp3 + TrO7 + rxs其中M2 +是二价金属,M3 +是三价金属,T 是钒,钨或钼。 微晶体很小,通过常规的x射线衍射技术是不可检测的,但是高分辨率电子显微镜显示,大部分微晶体由分子内分散在二价金属氧化物晶体结构中的氧化铝的固溶体构成。 微晶的另一部分由尖晶石相构成。 塌陷组合物适合作为硫氧化物吸收剂,具有相对较高的容量和相对较快的吸收和解吸速率,并且也适合作为氮氧化物还原催化剂。 塌陷组合物可以通过以单金属盐形式对具有中间阴离子的层状混合氢氧化物粘土进行热处理来制备。 与以前的制造方法中使用的试剂相比,制造方法的试剂相对不含盐。
