Abstract
Bulk metallic catalyst precursors are provided that include a Group VIB metal, such as Ni, a Group VIII metal, such as Mo or W, an organic-compound based component, and an organo-metalloxane polymer or gel. The catalyst precursors can further include a binder. Amorphous sulfided catalysts formed from the catalyst precursors are also provided. The catalyst precursor can have a surface area of about 50 m2/g or less.
