Process for producing catalyst composition containing nickel, aluminum oxide and zirconium dioxide for hydrogenating nitrile, aromatic hydrocarbon, nitro compound, catalyst composition and hydrogenating nitrile, aromatic hydrocarbon, nitro compound Method

摘要

The present invention relates to a process for preparing a catalyst composition containing nickel, alumina and zirconia by simultaneous precipitation of nickel, aluminium and zirconium from a mixed salt solution by means of an aqueous solution of an excess of a basic compound as precipitant at pH 7 to 10 and 60 to 120 DEG C, deposition on a support material, filtration, drying and reduction, and to specific catalyst composition and the use thereof as catalyst for the hydrogenation of nitriles, aromatic hydrocarbons, nitro compounds and olefins in the liquid phase.
