Abstract
A catalyst system for treating sulfur and nitrogen contaminated hydrocarbon feedstock including a matrix, at least one support medium substantially uniformly distributed through said matrix, a first catalytically active metal phase supported on said support medium, said first catalytically active metal phase comprising a first metal and a second metal each selected from group VIII of the periodic table of elements, said first metal being different from said second metal, a second catalytically active metal phase supported on said matrix, said second catalytically active metal phase comprising a third metal and a fourth metal each selected from group VIII of the periodic table of elements and a fifth metal selected from group VIb of the periodic table of elements, said third metal being different from said fourth metal. The catalyst system is prepared in a method which provides the system with excellent hydroisomerization, HDS, and HDN properties.
