  • Patent number: 8557105
    Abstract: 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.

  • Patent number: 8445399
    Abstract: Hydrocarbon-soluble molybdenum catalyst precursors include a plurality of molybdenum cations that are each bonded with a plurality of organic anions to form an oil soluble molybdenum salt. A portion of the molybdenum atoms are in the 3+ oxidation state such that the plurality of molybdenum atoms has an average oxidation state of less than 4+, e.g., less than about 3.8+, especially less than about 3.5+. The catalyst precursors can form a hydroprocessing molybdenum sulfide catalyst in heavy oil feedstocks. The oil soluble molybdenum salts are manufactured in the presence of a reducing agent, such as hydrogen gas, to obtain the molybdenum in the desired oxidation state. Preferably the reaction is performed with hydrogen or an organic reducing agent and at a temperature such that the molybdenum atoms are reduced to eliminate substantially all molybdenum oxide species.

  • Publication number: 20120132591
    Abstract: 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.

  • Patent number: 8097149
    Abstract: Oil soluble catalysts are used in a process to hydrodesulfurize petroleum feedstock having a high concentration of sulfur-containing compounds and convert the feedstock to a higher value product. The catalyst complex includes at least one attractor species and at least one catalytic metal that are bonded to a plurality of organic ligands that make the catalyst complex oil-soluble. The attractor species selectively attracts the catalyst to sulfur sites in sulfur-containing compounds in the feedstock where the catalytic metal can catalyze the removal of sulfur. Because the attractor species selectively attracts the catalysts to sulfur sites, non-productive, hydrogen consuming side reactions are reduced and greater rates of hydrodesulfurization are achieved while consuming less hydrogen per unit sulfur removed.

  • Patent number: 7960440
    Abstract: The particle sizes of agglomerates of carbon nanospheres are reduced by dispersing the carbon nanospheres in an organic solvent. The carbon nanospheres are multi-walled, hollow, graphitic structures with an average diameter in a range from about 10 nm to about 200 nm, more preferably about 20 nm to about 100 nm. Spectral data shows that prior to being dispersed, the carbon nanospheres are agglomerated into clusters that range in size from 500 nm to 5 microns. The clusters of nanospheres are reduced in size by dispersing the carbon nanospheres in an organic solvent containing at least one heteroatom (e.g., NMP) using ultrasonication. The combination of organic solvent and ultrasonication breaks up and disperses agglomerates of carbon nanospheres.
