摘要

abstract "supported hydrotreating catalysts having enhanced activity, hydrotreating method and supported catalyst formation process". This invention provides supported catalysts comprising a carrier, phosphorus, at least one group vi metal, at least one group viii metal and a polymer. in the catalyst, the molar ratio of phosphorus to group vi metal is about 1: 1.5 to less than about 1:12, the molar ratio of group vi metal to group viii metal is about 1: 1 to about 5: 1, and the polymer has a carbon backbone and comprises functional groups having at least one heteroatom. There is also provided a process for preparing such supported catalyst, as well as methods for hydrotreating, hydrodenitrogenation and / or hydrodesulfurization using supported catalysts. 1/1
