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.
