  • Publication number: 20110303585
    Abstract: The instant invention pertains to a process for treating a feed, for example a Light Cycle Oil (LCO), having a high content of S and/or N impurities and/or a high content of aromatics, comprising the following steps, in particular in such an order a step of desulphurisation (HDS) and denitrification (HDN) of a feed, in particular LCO, is passed in presence of hydrogen over a catalyst, containing metals of the group VI B and VIII, leading to an effluent, optionally a step of stripping of the effluent, at least a subsequent step for dearomatization (HDA) in which at least a portion of the effluent, optionally stripped, is passed in presence of hydrogen over a catalyst comprising a combination of platinum and palladium supported on a carrier comprising silica-alumina dispersed in an alumina binder wherein the amount of alumina binder is 5-50 wt. % based on the total weight of the silica-alumina and alumina binder present in the carrier and wherein the silica-alumina comprises 5-50 wt.

  • Publication number: 20070090023
    Abstract: The invention relates to a process for upgrading hydrocarbonaceous feedstreams by hydroprocessing using bulk bimetallic catalysts. More particularly, the invention relates to a catalytic hydrotreating process for the removal of sulfur and nitrogen from a hydrocarbon feed such as a fuel or a lubricating oil feed. The catalyst is a bulk catalyst containing at leas one Group VIII metal and at least one Group VIB metal. The catalyst is prepared hydrothermally.

  • Publication number: 20050040080
    Abstract: A method for upgrading a naphtha feed to a naphtha product containing less than about 10 wppm of nitrogen and less than about 15 wppm sulfur, the method comprising contacting said naphtha feed with hydrogen in the presence of a bulk multimetallic catalyst under effective reactor conditions to hydrodesulfurize and hydrodenitrogenize said naphtha feed to produce said naphtha product, wherein said bulk multimetallic catalyst comprises at least one Group VIII non-noble metal and at least two Group VIB metals.
