Acidic promotion of transition metal sulfide catalysts for selective hydrogenation |
摘要 |
It has now been discovered that hydrocarbon feeds containing a polycyclic aromatic compound or mixtures thereof can be selectively hydrogenated by contacting the feed with a transition metal catalyst and hydrogen in the presence of an acid to provide a hydrocarbon mixture in which the aromatic content consists substantially of mono- and di-aromatic compounds. Useful acids include Lewis acids and acids having a pKa in the range of 0 to about -10.
