Nikkeli/aluminiumoksidi-katalysaattori, menetelmä sen valmistamiseksi, sen käyttö sekä menetelmä aromaattisten hiilivetyjen hydraamiseksi katalysaattorin avulla

摘要

The invention relates to a nickel/aluminium oxide catalyst having a nickel content of 10 to 60% by weight, based on the overall catalyst, the nickel crystallites having an average diameter of 15 nm to 50 nm. The nickel/aluminium oxide catalyst is produced by mixing a nickel compound with an aluminium oxide precursor compound, moulding the mixture, drying the moulding and activating the resulting catalyst precursor in a hydrogen-containing gas stream at temperatures of 230 to 550@C. The nickel/aluminium oxide catalyst can be used in a process for the hydrogenation of aromatic hydrocarbons.
