Aromatic reduction of residue oil of naphtha cracking over bimetallic Pt−Pd catalysts supported on mesoporous molecular sieve

Article

Abstract

An Al-containing mesoporous molecular sieve (Al-MMS) was prepared by hydrolysis of H2SiF6 and Al(NO3)3·9H2O. NH3-TPD results suggest that the acidity of Al-MMS was less than that of dealuminated zeolite. Y. The potential use of mesoporous molecular sieve as a new support material for dearomatization of residue oil of naphtha cracking was described. In case of C9 + and PGO feed, Pt−Pd/Al-MMS showed a higher activity than Pt−Pd/dealuminated zeolite Y catalyst. This is ascribed to its better accessibility of bulky molecules, and much less cracking activity due to mild acidity, indicating high yield of liquid. Thus, Pt−Pd/Al-MMS catalyst can be applied effectively to the hydrogenation of aromatic compounds in the residue oil of a commercial naphtha cracker.
