Abstract
The instant invention relates to a process to produce liquid products through the hydroprocessing of hydrocarbonaceous feedstreams in the presence of a bulk metal hydroprocessing catalyst.
Claims30
A process for producing liquid products from a hydrocarbonaceous feedstream comprising:
- a) contacting a hydrocarbonaceous boiling range feedstream containing aromatics, nitrogen and organically bound sulfur contaminants in a reaction stage with a bulk metal hydroprocessing catalyst in the presence of hydrogen-containing treat gas thereby producing a reaction product comprising at least a vapor product and a liquid product, wherein said hydrocarbonaceous feedstream is contacted with said bulk metal catalyst under effective hydroprocessing conditions and said bulk metal hydroprocessing catalyst comprises:
- i) a single Group VIB metal component selected from molybdenum and tungsten;
- ii) a Group V metal component selected from vanadium, niobium, tantalum, and mixtures thereof;
- and
- iii) a Group VIII metal component selected from nickel, cobalt, iron, and mixtures thereof, wherein the metal components (calculated as oxides) comprise at least 50 wt. % of the catalyst, wherein the metal components are present in a ratio defined as (Group VIB+Group V):(Group VIII) such that said ratio, based on oxide forms of the metal components, is from 0.35:1 to 2:1.
