Abstract

Bulk metallic catalysts comprised of a Group VIII metal and a Group VIB metal and methods for synthesizing bulk metallic catalysts are provided. The catalysts are prepared by a method wherein precursors of both metals are mixed and interacted with at least one organic acid, such as glyoxylic acid, dried, calcined, and sulfided. The catalysts are used for hydroprocessing, particularly hydrodesulfurization and hydrodenitrogenation, of hydrocarbon feedstocks.
