    • A durable Pd-based alloy is used for a H2-selective membrane in a hydrogen generator, as in the fuel processor of a fuel cell plant. The Pd-based alloy includes Cu as a binary element, and further includes “X”, where “X” comprises at least one metal from group “M” that is BCC and acts to stabilize the β BCC phase for stability during operating temperatures. The metal from group “M” is selected from the group consisting of Fe, Cr, Nb, Ta, V, Mo, and W, with Nb and Ta being most preferred. “X” may further comprise at least one metal from a group “N” that is non-BCC, preferably FCC, that enhances other properties of the membrane, such as ductility. The metal from group “N” is selected from the group consisting of Ag, Au, Re, Ru, Rh, Y, Ce, Ni, Ir, Pt, Co, La and In. The at. % of Pd in the binary Pd—Cu alloy ranges from about 35 at. % to about 55 at. %, and the at. % of “X” in the higher order alloy, based on said binary alloy, is in the range of about 1 at. % to about 15 at. %. The metals are selected according to a novel process.

    • The invention provides for a method of making isoalcohols using syngas-to-alcohol catalyst and method of making it. The catalyst is a highly dispersed, alkali promoted, La stabilized, microcrystalline Cu.sub.2 O having a particle size of .ltoreq.6 nm in the presence of an alumina structural promoter, wherein on a mole % alkali free metals-only basis Cu is present in from 45 to 55%, Zn from 10 to 20%, Al from 10 to 25%, La from 5 to 15%, and wherein the alkali is from 0.01 to 0.91% K and from 3 to 6.5% Cs. The method of making it involves coprecipitation at a constant pH from a solution of soluble metal salts of copper, zinc, lanthanum and aluminum with an alkali hydroxide, washing the coprecipitate in the essential absence of CO.sub.2, drying and calcining it, then contacting it with K and Cs to form the promoted catalyst. The promoted catalyst is dried and recalcining to produce a catalyst precursor with highly dispersed CuO crystallites. The catalyst is activated in flowing hydrogen.
    • 本发明提供了使用合成气 - 醇催化剂制备异构醇的方法及其制备方法。 该催化剂是在氧化铝结构促进剂的存在下具有大小分散的碱促进的La稳定的微晶Cu2O,其具有的颗粒尺寸为<6nm,其中基于无碱金属的摩尔%的Cu存在于 45〜55%,Zn为10〜20%,Al为10〜25%,La为5〜15%,碱为0.01〜0.91%,Cs为3〜6.5%。 其制备方法涉及在铜,锌,镧和铝的可溶性金属盐与碱金属氢氧化物的溶液的恒定pH下共沉淀,在基本不存在CO 2的情况下洗涤共沉淀物,干燥并煅烧,然后将其与 K和Cs形成促进催化剂。 将促进的催化剂干燥并重新煅烧以产生具有高度分散的CuO微晶的催化剂前体。 催化剂在流动的氢气中活化。
