The present invention relates to a catalytic process for removing organonitrogen species from hydrocarbon mixtures such as refinery process feedstreams. More particularly, this invention relates to a new operating and catalyst loading strategies based on organonitrogen concentration, composition, and structure.

Operating method for hydrodenitrogenation

This invention relates to a process for activating a hydroprocessing catalyst and the use of activated catalyst for hydroprocessing. More particularly, hydroprocessing catalysts are activated in the presence of carbon monoxide. The catalysts that have been activated by CO treatment have improved activity.

Activating hydroprocessing catalysts using carbon monoxide and use of catalysts for hydroprocessing

This invention relates to supported multi-metallic catalysts for use in the hydroprocessing of hydrocarbon feeds, as well as a method for preparing such catalysts. The catalysts are prepared from a catalyst precursor comprised of at least one Group VIII metal and a Group VI metal and an organic agent selected from the group consisting of amino alcohols and amino acids. The catalyst precursor is thermally treated to partially decompose the organic agent, then sulfided.
