Catalysts for dewaxing of hydrocarbon feeds, particularly feeds with elevated sulfur and nitrogen levels, are provided. The dewaxing catalysts include a zeolite with a low silica to alumina ratio combined with a low surface binder, or alternatively the formulated catalyst has a high ratio of zeolite surface area to external surface area.

Hydroprocessing catalysts with low surface area binders

The instant invention relates to a process to produce low sulfur diesel products through the hydrodesulfurization of low nitrogen diesel boiling range feedstreams in the presence of solid acidic materials.

Solid acid assisted deep desulfurization of diesel boiling range feeds

A two stage process for selectively hydrodesulfurizing olefinic and sulfur and nitrogen-containing naphtha feedstreams wherein the first stage is a nitrogen removal stage to produce a naphtha feedstream having reduced levels of nitrogen compounds and a second stage wherein the naphtha feedstream having reduced levels of nitrogen compounds is hydrodesulfuried with a catalyst and under conditions selective to remove sulfur with minimum olefin saturation.

Nitrogen removal from olefinic naphtha feedstreams to improve hydrodesulfurization versus olefin saturation selectivity

The instant invention relates to a process to produce high octane, low sulfur naphtha products through the removal of basic nitrogen-containing compounds with subsequent skeletal isomerization of feed olefins and hydrotreating.

Producing low sulfur naphtha products through improved olefin isomerization

The present invention is directed at a process to isomerize Chydrocarbon feedstreams by contacting a Chydrocarbon feedstream with a steamed catalyst.
