Abstract
This disclosure relates to supported multi-metallic catalysts for use in the hydrotreating of hydrocarbon feeds. The catalysts are prepared from a catalyst precursor comprised of at least one Group VIB metal, at least one Group VIII metal and an organic acid. The catalyst precursor is thermally treated to partially decompose the organic acid, then sulfided. The catalysts have a high carbon-as-carboxyl to total carbon ratio (Ccarboxy/Ctotal) as a result of a unique post-metal calcination method employed during the manufacture of the catalyst.
Claims11
A process for hydrotreating a hydrocarbon feedstock, comprising:
- contacting the feedstock with a hydrotreating catalyst under hydrotreating conditions to produce a hydrotreated effluent, wherein the hydrotreating catalyst comprises:
- (a) an inorganic catalyst support;
- and
- (b) a partially oxidized metal-organic component;
- wherein the catalyst has (i) a loss-on-ignition of greater than 1 to 20 wt. % and (ii) a carbon-as-carboxyl to total residual carbon ratio (Ccarboxy/Ctotal) of at least 0.10 as determined by X-ray photoelectron spectroscopy.
