    • Anode catalysts for conversion of hydrocarbon feeds in solid oxide fuel cell membrane reactors. An anode catalyst may be a mixture of a metal with a metal oxide, for example a mixture of copper or copper-nickel alloy or copper-cobalt alloy with Cr2O3. Mixed oxides can be prepared by dissolving into water soluble salts of the different metals, chelating the metal ions with a chelating agent, neutralizing the solution, removing water by evaporation to form a gel which then is dried, and finally heating the dried gel to form a mixed oxide of the different metals. The chelating agent can be citrate ions, and ammonia can be added to the solution until the pH of the solution is about 8. The mixed oxide so formed then is reduced, for example by hydrogen, to form a composite comprising the metal (Cu, Cu—Co, Cu—Ni) and metal oxide, here Cr2O3. Typically, the composite oxides so formed comprise approximately spherical nanoparticles, and the reduced composites are nanoparticles comprising very small particles of the metal within a network of the oxide, Cr2O3.

    • A recycling system for hydroxylamine formation and oximation is proposed. The recycling system includes a hydroxylamine formation zone, an oximation zone, a purification zone, and an adjusting zone having a nitrate absorption tower. An inorganic process solution, used by the recycling system, partially enters the nitrate absorption tower supplementing nitrate, followed by mixing with the residual inorganic process solution, thereby reducing the loss rate of hydroxylamine in the inorganic process solution due to degradation. In addition, the organic impurities with high boiling point in the inorganic process solution can be effectively removed in the purification zone. As a result, the reduced activity or selectivity of the catalyst for hydroxylamine formation, caused by the toxic effects of these organic impurities on the catalyst, can be avoided, and hence, a high concentration of hydroxylamine can be obtained.
    • 提出了羟胺形成和肟化的循环系统。 回收系统包括羟胺形成区,肟化区,净化区和具有硝酸盐吸收塔的调节区。 由再循环系统使用的无机工艺溶液部分地进入补充硝酸盐的硝酸盐吸收塔,然后与剩余的无机工艺溶液混合,从而降低由于降解导致的无机工艺溶液中羟胺的损失率。 此外,可以在净化区域中有效地除去无机工艺溶液中具有高沸点的有机杂质。 结果,可以避免由这些有机杂质对催化剂的毒性作用引起的羟胺形成催化剂的活性降低或选择性降低,因此可以获得高浓度的羟胺。
