Supported Ruthenium catalyst and process for hydrogenation of aromatic amines in presence of this catalyst
摘要
Hydrogenation of an amine with at least one aromatic ring-bonded amine group by reaction with hydrogen in presence of a supported catalyst with 0.01-20 wt.% active metal comprising ruthenium alone or with a sub-Group I, VII or VIII metal is such that the support has: (I) a BET surface area above 30 but below 70 m2/g; and (II) a macropore (diameter above 50nm) content above 50% and a mesopore (diameter 2-50nm) content below 50%.
