    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an amine at a high conversion without yielding by-products, and to obtain a catalyst for producing the amine. SOLUTION: This method comprises production of an amine by the reaction of a primary or secondary alcohol with a nitrogen compound selected from ammonia and primary and secondary amines at 80-250 deg.C, 0.1-40 MPa in the presence of a catalyst consisting of zirconium, copper, and nickel. The catalytically active ingredient contains 20-85 wt.% of an oxygen-containing zirconium compound (as calculated as ZrO2 ), 1-30 wt.% of an oxygen-containing copper compound (as calculated as CuO), 4-70 wt.% of an oxygen-containing nickel compound (as calculated as NiO), and 0-10 wt.% of an oxygen-containing aluminum and/or manganese compound(s) (as calculated as Al2 O3 and/or MnO2 ), but no oxygen-containing cobalt or molybdenum compound.

    Abstract: PROBLEM TO BE SOLVED: To enable to industrially simply and profitably obtain the subject compound from a primary amine and a diol by using a specific copper- containing hydrogenation/dehydrogenation catalyst. SOLUTION: This method for producing an N-substituted cyclic amine of formula I comprises reacting (C) a compound of the formula: R -NH2 [R is an (alkoxy)alkyl, an aryl, etc.,] with (D) a compound of the formula: HO-A-OH A is an alkylene (substituted by a group of the formula: R (R is R ), a group of the formula: (CH2 )n -[O-(CH )m ]r , [(m), (n) are each 2-8; (r) is 1-3]} in the presence of a coppercontaining catalyst. The copper-containing catalyst is obtained by impregnating an inactive carrier (e.g. silicon dioxide, a silicate or zeolite) with (A) hydrogen and (B) the aqueous ammine complex solution of an easily pyrolytic copper compound (e.g. copper carbonate, copper oxalate or copper formate)(preferably an ammoniacal copper carbonate solution), drying the impregnated carrier, and subsequently calcining the dried product, and contains the copper in an amount of 5-50wt.% converted into CuO on the basis of the whole amount of the calcined catalyst.

    Abstract: PROBLEM TO BE SOLVED: To produce an open-cell inorganic foam product without removing the amount of an organic material expressed in terms of weight by thermal decomposition and without beating relatively large cells and closing the foam cells. SOLUTION: A slip material comprising a baking inorganic powder, an evaporable liquid material capable of making the slip material flowable and, as necessary, an expanding gas forming material are converted into one expanded product under liberating the expanding gas in an expansion process and one treatment of the expanded product is carried out so as to make the slip material unflowable. An intermediate of open cells is formed and the residual material is removed from the liquid material. Optional other materials are removed from the intermediate to form a green foam material, which is then baked to form a baked open-cell inorganic foam product.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an amine by a reaction in the presence of a catalyst using a nitrogen compound selected from ammonia, a primary and a secondary amines and hydrogen. SOLUTION: A catalytically active composition of a catalyst after the production and prior to the treatment with hydrogen comprises 22-45 mass % of an oxygen-containing compound of zirconium, 1-30 mass % of an oxygen-containing compound of copper and 5-50 mass % of an oxygen-containing compound of nickel in >1 molar ratio of nickel to copper and further comprises 5-50 mass % of the oxygen-containing compound of cobalt calculated as CoO, 0-5 mass % an oxygen-containing compound of molybdenum and 0-10 mass % of an oxygen-containing compound of the calculated aluminum and/or manganese. Thereby, the economical efficiency of a conventional method is improved and the amine is produced by a technically simple method which can be carried out with a high aldehyde conversion rate and a high ketone conversion rate, a high yield, a high selectivity, a high catalyst useful life and a high mechanical stability of a catalyst molded product.

    Abstract: PROBLEM TO BE SOLVED: To provide catalyst composition by which oxidation of SOx in exhaust combustion gas containing oxygen is mostly avoided and also NOx is reduced. SOLUTION: TiO2 , WO3 and V2 O5 are contained in the catalyst composition for reduction of NOx . Distribution of pore diameter at least on both sides is in the ranges within 5-30nm and 45-100nm. V2 O5 is mainly distributed in the whole of larger pore in the distribution of pore diameter at least on both sides. In a method for producing the catalyst composition, firstly TiO2 , WO3 and an arbitrary additive are kneaded/mixed. V2 O5 or its precursor is dissolved in a solvent. The obtained solution is mixed with an organic polymer. Then, the solution mixed with the above-mentioned polymer is mixed with the first mixture. The produced composition is molded, dried and burned.
