초록

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.

What is claimed is: 1. An amorphous bulk metallic catalyst precursor composition comprising a) cobalt, b) molybdenum or tungsten, and c) from at least about 20 wt. % to about 60 wt. % of a carbon-containing compound based on a carboxylic acid-containing organic complexing agent, the catalyst precursor composition having a surface area of 16 m2/g or less based on BET.
