The present invention relates to the processing of hydrocarbon-containing feedstreams in the presence of an interstitial metal hydride comprised of at least one chemical element selected from Groups 3-11 (including the lanthanides, atomic numbers 58 to 71), and at least one chemical element selected from Groups 13-15 from the IUPAC Periodic Table of Elements. These interstitial metal hydrides, their catalysts and processes using these interstitial metal hydrides and catalysts of the present invention improve overall hydrogenation, product conversion, as well as sulfur reduction in hydrocarbon feedstreams.

Group 13-15 interstitial metal hydride catalysts and associated processes

Catalysts for experimentation are produced having a controlled matrix pore structure. The manufacturing process utilizes tape casting in the drying procedure in which a catalyst slurry is cast on a substrate and dried at a temperature of between about 50&#xb0; C. to 200&#xb0; C. for a period of time of about 0.1 to 1.0 hour. The dried catalyst particles can be removed from the substrate by several techniques, including scraping, burning, and deforming the substrate material. The resulting catalytic particles can be produced in an amount of about ca. 3 g to 300 g from slurries with volumes between 5 cc to 500 cc, which are suitable for small scale FCC reactors and for high throughput experimentation.

Drying device for producing small quantities of controlled particle size catalysts which are appropriate for use in fluidized bed operations such as fluid catalytic cracking

A three-step process of removing sulfur from naphtha feeds. The steps include a first hydrotreating step, a mercaptan removal agent and an adsorbent containing a reactive metal on an inorganic support. Step one removes at least 95 wt. % of the sulfur compounds while preserving at least 50 wt. % of the olefins. Treatment with the mercaptan removal agent lowers the sulfur content to 30 wppm total sulfur and final naphtha product contains leas than 10 wppm total sulfur.

Process for removing sulfur from naphtha

A process for hydroprocessing a distillate stream to produce a stream exceptionally low in sulfur, with total aromatics and polynuclear aromatics being moderately reduced. A distillate stream is hydrodesulfurized in a first hydrodesulfurization stage. The product stream thereof is passed to a first separation stage wherein a vapor phase product stream and a liquid product stream are produced. The liquid phase product stream is passed to a second hydrodesulfurization stage and the product stream thereof is passed to a second separation stage wherein a vapor phase product stream and a liquid product stream low in sulfur are produced. At least a portion of the vapor product stream from said second separation stage can be cascaded to the first hydrodesulfurization stage.

Production of low sulfur distillates

A distillate fuel composition boiling in the range of about 190&#xb0; C. to 400&#xb0; C. with a T10 point greater than 205&#xb0; C., and having a sulfur level of less than about 100 wppm, a total aromatics content of about 15 to 35 wt. %, a polynuclear aromatics content of less than about 3 wt. %, wherein the ratio of total aromatics to polynuclear aromatics is greater than about 11.

Low sulfur distillate fuels

The invention relates to a process for forming a low-sulfur motor gasoline and the product made therefrom. In one embodiment, process involves separating a catalytically cracked naphtha into at least a light fraction boiling below about 165&#xb0; F. and a heavy fraction boiling above about 165&#xb0; F. The light fraction is treated to remove sulfur by a non-hydrotreating method, and the heavy fraction is hydrotreated to remove sulfur to a level of less than about 100 ppm.

Low-sulfur fuel

The invention relates to a process for converting cycle oils produced in catalytic cracking reactions into olefin and naphtha. More particularly, the invention relates to a process for hydroprocessing a catalytically cracked light cycle oil, and then re-cracking it in an upstream zone of the primary FCC riser reactor.

Cycle oil conversion process

A process for producing distillate boiling range streams that are low in both sulfur and aromatics. A distillate feedstock is treated in a first hydrodesulfurization stage in the presence of a hydrogen-containing treat gas and a hydrodesulfurization catalyst, thereby resulting in partial desufurization of the stream. The partially desulfurized distillate stream is then treated in a second hydrodesulfurization stage, also in the presence of a hydrogen-containing treat gas and a hydrodesulfurization catalyst. The hydrogen-containing treat gas is cascaded from the next downstream reaction stage, which is an aromatics hydrogenation stage.

Production of low sulfur/low aromatics distillates

The invention relates to a process for converting cycle oils produced in catalytic cracking reactions into light olefin and naphtha. More particularly, the invention relates to a process for hydroprocessing a catalytically cracked light cycle oil in order to form a hydroprocessed cycle oil containing a significant amount of tetralins. The hydroprocessed cycle oil is then re-cracked in an upstream zone of the primary FCC riser reactor.

A process for producing polypropylene from olefins selectively produced from a catalytically cracked or thermally cracked naphtha stream is disclosed herein. The naphtha stream is contacted with a catalyst containing from about 10 to 50 wt. % of a crystalline zeolite having an average pore diameter less than about 0.7 nanometers at reaction conditions which include temperatures from about 500&deg; C. to 650&deg; C. and a hydrocarbon partial pressure from about 10 to 40 psia. The catalyst may be pre-coked with a carbonaceous feed. Alternatively, the carbonaceous feed used to coke the catalyst may be co-fed with the naphtha feed.

Process for selectively producing propylene in a fluid catalytic cracking process

The invention relates to a method for treating naphtha, such as catalytically cracked naphtha, in order to remove acidic impurities, such as mercaptans. In particular, the invention relates to a method for mercaptans having a molecular weight of about C (C H S&equals;90 g/mole) and higher, such as recombinant mercaptans.

Continuous naphtha treatment method

The invention relates to a process for forming a low-sulfur motor gasoline and the product made therefrom. In one embodiment, process involves separating a catalytically cracked naphtha into at least a light fraction boiling below about 165&deg; F. and a heavy fraction boiling above about 165&deg; F. The light fraction is treated to remove sulfur by a non-hydrotreating method, and the heavy fraction is hydrotreated to remove sulfur to a level of less than about 100 ppm.

Low-sulfur fuel and process of making

A fluid catalytic cracking (FCC) process performed in a FCC process unit containing a reactor, a regenerator and an outboard vessel. Catalyst particles containing vanadium are circulated back and forth from the reactor to the regenerator and back and forth from the regenerator and the outboard vessel. The outboard vessel contains a vanadium trap material that removes vanadium from at least a portion of the catalyst particles.

Vanadium removal in FCC by use of an outboard vessel

A process for removing sulfur compounds from hydrocarbon feedstreams, particularly those boiling in the naphtha range, by contacting the feedstream with an adsorbent comprised of cobalt and one or more Group VI metals selected from molybdenum and tungsten on a refractory support. This invention also relates to a process wherein a naphtha feedstream is first subjected to selective hydrodesulfurization to remove sulfur but not appreciably saturate olefins. A product stream is produced containing mercaptans that are removed by use of the cobalt-containing adsorbents of the present invention.

Removal of sulfur compounds from hydrocarbon feedstreams using cobalt containing adsorbents in the substantial absence of hydrogen

The invention relates to a process for converting cycle oils produced in catalytic cracking reactions into olefinic naphthas. More particularly, the invention relates to a process for hydroprocessing a catalytically cracked light cycle oil, and then re-cracking in an out-board FCC reactor it in order to form a naphthenic blend-stock.
