    摘要： Aromatic amines are produced by hydrogenation of the associated aromatic nitro compounds in the gas phase over fixed catalysts. The catalysts contain active hydrogenation metals on supports. The reaction is conducted at a pressure of 2-50 bar and at a temperature in the range 250.degree.-500.degree. C. under adiabatic conditions. A circulating gas is passed over the catalyst, which circulating gas contains 3-150 moles of hydrogen, 2-100 moles of the amino groups to be formed per mole of nitro groups, and 2 to 6 moles of water per amino group equivalent. The amine and water formed, as well as a purification stream, are separated from the circulating gas. Thereafter the circulating gas is enriched with volatilised aromatic nitro compound and fresh hydrogen and recycled.

    摘要： The catalyst according to the present invention can be utilized effectively as an ozone decomposing catalyst for catalytically decomposing to eliminate ozone contained in a gas or as an ozone deodorizing catalyst for decomposing offensive odor ingredients contained in a gas by catalytic oxidation under the pretense of ozone, and it comprises a composition containing Mn oxide, metal Pd and/or Pd oxide as the essential ingredients formed as a thin film on a support. Further, the performance of the catalyst can be improved by using Mn oxide and Pd as the essential ingredient and using an alumina sol as a binder upon preparation.

    摘要： The invention relates to a process for the production of a catalyzer and a catalyzer for the removal of polluting components from exhaust gases of internal combustion engines, particularly Otto-engines, by using carrier materials provided with catalytically effective metallic compounds. The catalyzer is not only simple and cost-effective to produce but also is very efficient at removing polluting components from exhaust gases, can be operated with leaded gasoline and has a comparatively long life components of the catalyzer include approx. 22-26% by weight of cobalt oxide, approx. 8-15% by weight manganous oxide, approx. 4-6% by weight copper oxide, approx. 25-35% by weight clay, and approx. 27-35% by weight talc. All these components are first premixed together in a dry powder form, homogenized and brought to the desired final particle size. Subsequently the powder mixture to be plastified is agitaled in a mixer and granulated through a sieve resultant granulate is then pressed into molds to be dried at approx. 50-150 degrees C and then burned at a temperature of approx. 850-900 degrees C.
