    Abstract: PROBLEM TO BE SOLVED: To produce a carried catalyst used for converting a carboxylic acid or its ester into an aldehyde by a selective hydrogenation reaction, having reasonable stability, capable of being regenerated, hardly or quite not forming a by-product, having at least comparable selectivity with the corresponding non-carried catalyst. SOLUTION: This method for producing an aldehyde of formula I (R is an aliphatic, alicyclic, aromatic or aromatic aliphatic group which may be substituted, if necessary, with one or more substituents and/or if necessary, may have more heterogeneous atom) comprises selectively hydrogenating an acid of the formula: R-COOH or an ester of the acid with a 1-10C alcohol with hydrogen in the presence of a metal oxide catalyst in a gaseous phase. Therein, the hydrogenation is carried out in the presence of the carried catalyst containing a metal oxide suitable for the selective hydrogenation of the carboxylic acid or the carboxylate ester as an essential catalyst on SiC (silicon carbide) as a carrier at a temperature of 150-450 deg.C under a pressure of 0.1-150 bars.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing corresponding aldehydes in high yield and selectivity by reacting a carboxylic acid or an ester thereof with hydrogen. SOLUTION: This method for synthesizing the aldehyde of general formula I [R1 to R3 are each hydrogen, a 1-6C alkyl, a 3-8C cycloalkyl, an aryl, a 7-12C alkylphenyl or a 7-12C phenylalkyl, or R1 and R2 may form a 3- to 7-membered alicyclic ring by bonding to each other] comprises reacting the carboxylic acid or the ester thereof, represented by general formula II [R1 to R3 are same as the above; R4 is hydrogen, a 1-6C alkyl, a 3-8C cycloalkyl, an aryl, a 7-12C alkylphenyl or a 7-12C phenylalkyl] with the hydrogen in a vapor phase in the presence of a catalyst containing zirconium oxide and one or more kinds of lanthanoid elements in the presence of water.

    Abstract: PROBLEM TO BE SOLVED: To provide a highly dispersed active component and to ensure high sintering stability and aggregation stability by applying a catalytically active metal to a support modified in the form of a chloride-free dissolved amine complex, acetylacetonate complex or allyl complex. SOLUTION: An inner support material such as granular SiO2 is pretreated by heating before coating with a modifier preferably used in the form of an alkoxide. The inner support material is then impregnated into a liquid phase, e.g. in an aqueous or organic phase or into a gaseous phase, e.g. by chemical vapor deposition. The resulting support material modified in the form of a chloride-free amine complex, acetylacetonate complex or allyl complex is optionally hydrolyzed, dried and calcined. A catalytically active metal such as Pd or Pt is applied to the modified support material by impregnation or ion exchange and then drying and optional calcination are carried out.

    Abstract: PROBLEM TO BE SOLVED: To provide a process for catalytically hydrogenating a hydrocarbon stream by which the fewest possible undesired secondary components such as oligomers and/or polymers and/or cracking products are formed. SOLUTION: The hydrocarbon stream is catalytically hydrogenated by adding a basic compound to the starting material stream without using a different solvent from the hydrocarbon stream to be hydrogenated. Thereby, the formation of undesired secondary components on the catalyst is effectively prevented. COPYRIGHT: (C)2003,JPO

    Abstract: PROBLEM TO BE SOLVED: To mold a catalytically active monolith without largely generating the peeling of an active compsn. by using an impregnation medium the surface tension of which is specific value or less when a catalytically active substance is applied to a structural carrier or monolith. SOLUTION: When a catalytically active substance is applied to a structural carrier or monolith, a carrier web is allowed to advance at a predetermined known speed from a roll R1 so as to be passed through a bending system and the bath B of a container containing an impregnation medium with surface tension of 50 mN/m or less through a tensile roll to be fed to a heating zone. In this heating zone, the carrier web is heated to drying temp. T1 by a plurality of radiation heaters H and subsequently heated to calcination temp. T2 and this heated carrier web coated with an active compsn. is cooled to be gathered on a roll R2 for further processing. By this constitution, a catalytically active monolith can be molded without generating the large peeling of the active compsn.
