METHODS OF PREPARING BULK GROUP VIII/GROUP VIB METAL CATALYSTS

摘要

Bulk metallic catalysts comprised of a Group VIII metal and a Group VIB m etal and methods for synthesizing bulk metallic catalysts are provided. The catalysts are prepared by a method wherein precursors of both metals are mix ed and interacted with at least one organic acid, such as glyoxylic acid, dr ied, calcined, and sulfided. The catalysts are used for hydroprocessing, par ticularly hydrodesulfurization and hydrodenitrogenation, of hydrocarbon feed stocks.
