Bulk bi-metallic catalysts made from precursors containing an organic agent

A method for preparing a catalyst precursor composition represented by the formula:

• (X)a(Y)b[(CH3CH2)cN(CH3)3]dOz
• wherein X is a Group VIII non-noble metal, Y is selected from Mo and W, c is an integer from about 10 to about 40, and the molar ratio of a:b is about 0.5/1 to about 3/1;
• which method comprises:
• (a) preparing a first aqueous solution of a Group VIII non-noble metal water soluble salt;
• (b) preparing a second aqueous solution of a Group VIB metal water soluble salt;
• (c) heating both said first and second solutions to a temperature from about 60° C. to about 150° C.;
• (d) adding an effective amount of an organic agent into said first aqueous solution;
• (e) introducing at least a portion of said second aqueous solution into said first aqueous solution;
• and
• (f) heating the resulting solution of step e) to an effective temperature to cause the precipitation of said catalyst precursor composition.

A process wherein a hydrocarbon feedstock is hydroprocessed at hydroprocessing conditions, which process comprises:
