Abstract: The invention relates to a process for preparing cyclohexanol and/or cyclohexanone, in which cyclohexene in a feed stream containing cyclohexene, cyclohexane and benzene is hydrated into cyclohexanol and/or oxidized into cyclohexanone, the cyclohexanol and/or cyclohexanone formed is separated from the reaction mixture thus obtained and the remaining cyclohexane and benzene are recycled to a preconnected cyclohexene preparation section, part of the stream that is recycled to the cyclohexene preparation section being subjected to a dehydrogenation reaction and the remaining part to a hydrogenation reaction, and the reaction streams thus obtained being combined to form the feed stream to the hydration and/or oxidation step.

Abstract: The invention relates to the preparation of a benzaldehyde by hydrogenation of a corresponding benzoic acid in the gas phase in the presence of a manganese containing catalyst on an acid carrier. The invention is characterized in that use is made of a catalyst prepared by a) coprecipitation, at a pH between 7 and 10, of a manganese salt and a salt from which an acid carrier is formed, b) subsequent calcination at a temperature between 300 and 700 &loz& C, c) followed by reduction with a hydrogen containing gas mixture. Preferably the catalyst contains oxides of aluminium, zirconium, titanium, hafnium and/or niobium.

Abstract: The invention is concerned with a process for removing mercury from organic, especially non-polar, media like liquid hydrocarbon mixtures, most preferably natural gas condensates, by contacting the media to be treated with a solid adsorbens, preferably an ion exchange resin, containing active thiol groups. By this method it is possible to remove mercury from the treated media in an amount of more than 97 %.

Abstract: The invention relates to a process for the preparation of cyclohexanol and/or cyclohexanone from cyclohexane, in which process the cyclohexane is dehydrogenated to cyclohexene preferably at a temperature of 200 to 700 DEG C and a pressure of 0.01 to 10 Mpa, the cyclohexene hydrated to cyclohexanol preferably at a temperature of -50 to 150 DEG C and a pressure of 0.01 to 10 MPa, and/or oxidized to cyclohexanone preferably at a temperature of 0 to 350 DEG C and a pressure of 0.01 to 200 MPa, the cyclohexanol and/or the cyclohexanone separated, and the unconverted cyclohexane and/or cyclohexene returned to the dehydrogenation step.
