Abstract: PROBLEM TO BE SOLVED: To provide an improved process for the preparation of an iron-doped ruthenium catalyst supported on carbon, and to provide its use for a selective liquid phase hydrogenation of a carbonyl compound to give a corresponding alcohol. SOLUTION: In the process for the preparation of the catalyst comprising iron in addition to ruthenium on the carbon support, the process comprises a stage of simultaneously precipitating the catalytically active components onto the support. The catalyst prepared can be used to obtain geraniol or nerol in good selectivity by in particular the hydrogenation of citral. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a process for carrying out reactions involving a liquid phase, a gaseous phase and a solid phase with improved mass transfer between the gas phase and the liq. and with isothermal processing. SOLUTION: The above purpose is achieved by an apparatus comprising (i) a dispersing element for dispersing a gas phase in a liq. phase to generate a reaction fluid, (ii) at least one reactor which processes an inlet, an outlet and a reactor space bounded by heat-removing wall which are spaced apart substantially uniformly along the main flow axis of the reaction fluid and which is fitted with a catalyst-coated metal fabric and (iii) a feed line which routes the reaction fluid from the dispersing element to the reactor inlet and is sufficiently short that the degree of dispersion of the reaction fluid does not substantially change in the course of the passage through the feed line.

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 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 reduce the residual content of an unsaturated compound after hydrogenation by using a catalyst containing a metal having the hydrogenation activities on an alumina carrier and representing the reflection of a specified X-ray refraction pattern as the catalyst used in the case of hydrogenating selec tively the unsaturated compound in hydrocarbon flows. SOLUTION: When an unsaturated compound in hydrocarbon flows containing the unsaturated compound is selectively hydrogenated by using a catalyst, the catalyst having at least a metal of one kind provided with hydrogenation activities on an alumina carrier and representing the reflection of the X-ray refraction pattern corresponding to the lattice face interval in the state of not being used represented by a separate table is used. As the metal of one kind provided with hydrogenation activities or a plurality of metals provided with hydrogenation activities, one kind or a plurality of kinds of metals selected from group VIII, group IX or group X of the periodical table are used as the metal provided with the hydrogenation activities. As the metal provided with hydrogenation activities, preferably a platinum and/or a palladium is used.

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.
