Novel methods for manufacturing carbon nanostructures (e.g., carbon nanospheres) that are highly dispersed include forming a precursor composition, polymerizing the precursor composition, applying a long chain hydrocarbon surfactant to the polymerized carbon material, and carbonizing the polymerized material (e.g., through pyrolysis) to form the carbon nanostructures. The long chain hydrocarbon surfactant facilitates the formation of dispersed carbon nanostructures during the carbonization step.

Novel methods for manufacturing carbon nanostructures (e.g., carbon nanospheres) that are highly dispersed include forming a precursor composition, polymerizing the precursor composition, extracting water from the polymerized carbon material using an organic solvent, and carbonizing the polymerized material (e.g., through pyrolysis) to form the carbon nanostructures. The extraction-treated polymerized carbon material forms carbon nanostructures that are less agglomerated than carbon nanostructures manufactured using a similar technique without solvent extraction of water.

A hydrocracking system involves introducing a heavy oil feedstock and a colloidal or molecular catalyst, or a catalyst precursor capable of forming the colloidal or molecular catalyst, into a hydrocracking reactor. The colloidal or molecular catalyst is formed in situ within the heavy oil feedstock by 1) premixing the catalyst precursor with a hydrocarbon diluents to form a catalyst precursor mixture, 2) mixing the catalyst precursor mixture with the heavy oil feedstock, and 3) raising the temperature of the feedstock to above the decomposition temperature of the catalyst precursor to form the colloidal or molecular catalyst. The colloidal or molecular catalyst catalyzes upgrading reactions between the heavy oil feedstock and hydrogen and eliminates or reduces formation of coke precursors and sediment. The colloidal or molecular catalyst can be the sole or primary hydrocracking catalyst in a stand-alone hydrocracking reactor or it can be used together with a porous supported catalyst within a fixed bed or ebullated bed reactor.


An ebullated bed hydroprocessing system, and also a method for upgrading an existing ebullated bed hydroprocessing system, involves introducing a colloidal or molecular catalyst, or a catalyst precursor capable of forming the colloidal or molecular catalyst, into an ebullated bed reactor. The colloidal or molecular catalyst is formed by intimately mixing a catalyst precursor into a heavy oil feedstock and raising the temperature of the feedstock to above the decomposition temperature of the catalyst precursor to form the colloidal or molecular catalyst in situ. The improved ebullated bed hydroprocessing system includes at least one ebullated bed reactor that employs both a porous supported catalyst and the colloidal or molecular catalyst to catalyze hydroprocessing reactions involving the feedstock and hydrogen. The colloidal or molecular catalyst provides catalyst in what would otherwise constitute catalyst free zones within the ebullated bed hydroprocessing system. Asphaltene or other hydrocarbon molecules too large to diffuse into the pores of the supported catalyst can be upgraded by the colloidal or molecular catalyst. A slurry phase reactor may be positioned upstream from one or more ebullated bed reactors or converted from an existing ebullated bed reactor.

A novel zeolite membrane is manufactured using zeolite seeds that are deposited on a support material. The seeds are then further grown in a secondary growth step to form a membrane with inter-grown particles. The pore size of the zeolite membrane is in a range between 3 angstrom and 8 angstrom, which allows water to flow through the membrane at a relatively high flux rate while excluding dissolved ions. The novel zeolite membrane is surprisingly efficient for desalinating sea water using reverse osmosis. The zeolite membrane is capable of high rates of water flux rate and high percentage of ion rejection.

Methods and systems for hydroprocessing heavy oil feedstocks to form upgraded material use a colloidal or molecular catalyst dispersed within heavy oil feedstock, pre-coking hydrocracking reactor, separator, and coking reactor. The colloidal or molecular catalyst promotes upgrading reactions that reduce the quantity of asphaltenes or other coke forming precursors in the feedstock, increase hydrogen to carbon ratio in the upgraded material, and decrease boiling points of hydrocarbons in the upgraded material. The methods and systems can be used to upgrade vacuum tower bottoms and other low grade heavy oil feedstocks. The result is one or more of increased conversion level and yield, improved quality of upgraded hydrocarbons, reduced coke formation, reduced equipment fouling, processing of a wider range of lower quality feedstocks, and more efficient use of supported catalyst if used with the colloidal or molecular catalyst, as compared to a conventional hydrocracking process or a conventional thermal coking process.

The present invention relates to novel composites that incorporate carbon nanospheres into a polymeric material. The polymeric material can be any polymer or polymerizable material compatible with graphitic materials. The carbon nanospheres are hollow, graphitic nanoparticles. The carbon nanospheres can be manufactured from a carbon precursor using templating catalytic nanoparticles. The unique size, shape, and electrical properties of the carbon nanospheres impart beneficial properties to the composites incorporating these nanomaterials.

Methods for hydrocracking a heavy hydrocarbon feedstock (e.g., heavy oil and/or coal resid) employ a catalyst composed of well dispersed metal sulfide catalyst particles (e.g., colloidally or molecularly dispersed catalyst particles, such as molybdenum sulfide), which provide an increased concentration of metal sulfide catalyst particles within lower quality materials requiring additional hydrocracking. In addition to increased metal sulfide catalyst concentration, the systems and methods provide increased reactor throughput, increased reaction rate, and higher conversion of asphaltenes and lower quality materials. Increased conversion of asphaltenes and lower quality materials also reduces equipment fouling, enables processing of a wider range of lower quality feedstocks, and leads to more efficient use of a supported catalyst if used in combination with the well dispersed metal sulfide catalyst particles.

Supported reactive catalysts having a controlled coordination structure and methods for their production are disclosed. The supported catalyst comprises catalyst particles having top or outer layer of atoms in which at least a portion of the atoms exhibit a controlled coordination number of 2. Such catalysts may be manufactured from intermediate precursor compositions that include a control agent in which a preponderance of the molecules are straight-chained rather than branched. The supported catalysts of the present invention are useful for the preparation of hydrogen peroxide with high selectivity in addition to other chemical conversion reactions. The catalyst and methods may be used for the concurrent in situ and ex situ conversion of organic compounds. In addition, a process is provided for catalytically producing hydrogen peroxide from hydrogen and oxygen feeds by contacting them with the catalysts of the invention and a suitable organic liquid solvent having a Solvent Selection Parameter (SSP) between 0.14 x 10^(-4) and 5.0 x 10^(-4).

Hydrocarbon-soluble molybdenum catalyst precursors include a plurality of molybdenum cations and a plurality of carboxylate anions having at least 8 carbon atoms. The carboxylate anions are alicyclic, aromatic, or branched, unsaturated and aliphatic, and can derived from carboxylic acids selected from 3-cyclopentylpropionic acid, cyclohexanebutyric acid, biphenyl-2-carboxylic acid, 4-heptylbenzoic acid, 5-phenylvaleric acid, geranic acid, 10-undecenoic acid, dodecanoic acid, and combinations thereof. The molybdenum salts have decomposition temperatures higher than 210 C. The catalyst precursors can form a hydroprocessing molybdenum sulfide catalyst in heavy oil feedstocks. Also disclosed are methods for making catalyst precursors and hydrocracking heavy oil using active catalysts.
