Novel adsorbents and their use in a process for the removal of sulfur compounds from distillate fuels are described herein. The novel adsorbents are comprised of nanocrystals of Ni having adsorbed on their surface phosphorus and/or phosphine species, which nanocrystals can be distributed in a micro-/meso-porous support material.

Adsorbent for ultradeep removal of sulfur compounds from distillate fuels

This invention relates to a two stage hydroprocessing process with stripping zones between the hydroprocessing zones and following the last hydroprocessing zone. The stripping occurs at high pressure and temperature with no disengagement between or following the hydroprocessing zones. There is recycle of high temperature gaseous effluent from the last stripping zone to the first stripping zone.

Hydroprocessing process with integrated interstage stripping

A process for producing a lubricating oil basestock having at least 90 wt. % saturates and a VI of at least 105 by selectively hydroconverting a raffinate from a solvent extraction zone in a two step hydroconversion zone followed by a hydrofinishing zone, and a lubricating oil basestock produced by said process.

Hydroconversion process for making lubricating oil basestocks

A three stage process for producing high quality white oils, particularly food grade mineral oils from mineral oil distillates. The first reaction stage preferably employs a sulfur resistant hydrotreating catalyst and produces a product suitable for use as a high quality lubricating oil base stock. The second reaction stage preferably employs a hydrogenation/hydrodesulfurization catalyst combined with a sulfur sorbent and produces a product stream which is low in aromatics and which has substantially &ldquo;nil&rdquo; sulfur. The final reaction stage employs a selective hydrogenation catalyst that produces a product suitable as a food grade white oil.

Process for the production of medicinal white oil

A process for producing a lubricating oil basestock having at least 90 wt. % saturates and a VI of at least 105 by selectively hydroconverting a raffinate from a solvent extraction zone in a two step hydroconversion zone followed by a hydrofinishing zone.

The present invention is directed to an improved isomerization process employing a catalyst wherein the catalyst comprises a pair of catalyst particles of different acidity utilized either as distinct beds of such discrete particles or as a mixture of such discrete particles. The isomerization process utilizing such a catalyst produces a product which exhibits higher VI as compared to products produced using either catalyst component separately or using a single catalyst having the average acidity of the two discrete catalysts.

Catalyst combination for improved wax isomerization

Plasma initiators that have become deactivated due to the accumulation of carbonaceous deposits, sulfur deposits, or both thereon can be regenerated by contact with a gas containing molecular hydrogen in the presence of microwave radiation.

Regenerating a plasma initiator using molecular hydrogen in the presence

Methane can be effectively converted to acetylene, ethylene, and hydrogen by subjecting the methane to continuous microwave radiation in the presence of at least one plasma initiator that is capable of initiating an electric discharge in an electromagnetic field.
