PREPARATION OF BULK METALLIC GROUP VIII/GROUP VIB METAL CATALYSTS

摘要

Bulk catalysts comprised of a Group VIII metal and a Group VI metals are prepared using commercial scale processes. The catalysts are prepared by a method wherein Group VI and Group VIII metal reagents are mixed and interacted with at least one organic complexing agent, dried, calcined, and sulfided. The catalysts are used for hydroprocessing, particularly hydrodesulfurizaton and hydrodenitrogenation, of hydrocarbon feedstocks.
