A HYDROGENATION CATALYST AND ITS PREPARATION

摘要

The present invention relates to an amorphous alloy hydrogenation catalyst and its preparation. The catalyst comprises 60 SIMILAR 98 wt.% of Ni, 0 SIMILAR 20 wt.% of FC, 0 SIMILAR 20 wt.% of a metal selected from the group consisted of Cr, Co, Mo, Mn and W, and 0.5 SIMILAR 30 wt.% Al, wherein the content of Fe and the content of the metal selected from the group consisted of Cr, Co, Mo, Mn and W are not simultaneously equal to 0; XRD shows that the catalyst has a wide diffraction peak only at the site where 2 theta is equal to 45+/-1 DEG in the range of 20 SIMILAR 80 DEG . The catalyst of the present invention is suitable for the hydrogenation processes of unsaturated compounds such as aromatic hydrocarbons, alkynes, alkenes, nitrocompounds, carbonyl compounds, nitriles etc., and especially, suitable for the hydrogen refining of caprolactam.
