Abstract: Heavy oil feeds are hydroprocessed in the presence of a solvent and in the presence of a catalyst with a median pore size of about 85 ? to about 120 ? under conditions that provide a variety of benefits. The solvent can be an added solvent or a portion of the liquid effluent from hydroprocessing. The processes allow for lower pressure processing of heavy oil feeds for extended processing times or extended catalyst lifetimes be reducing or mitigating the amount of coke formation on the hydroprocessing catalyst.

Abstract: This invention is directed to a process for producing a hydroprocessed product. The invention is particularly advantageous in that substantially less hydrogen is absorbed during the process relative to conventional hydroprocessing methods. This benefit is achieved by using a particular solvent as a co-feed component. In particular, the solvent component contains at least one single ring aromatic compound and has a relatively low boiling point range compared to the heavy hydrocarbon oil component used as another co-feed component.

Abstract: A polymer electroluminescent device is provided. The device includes an anode, a light-emitting layer, a cation-containing water-soluble polymer layer and a cathode formed in this order on a substrate wherein the cation-containing water-soluble polymer layer is formed by wet coating. The cation-containing water-soluble polymer layer as a secondary thin film layer is not dissolved in a solvent for the formation of the underlying light-emitting layer to prevent intermixing between the two layers, thereby enabling the formation of a multilayer structure by wet coating. In addition, the cation-containing water-soluble polymer layer attracts electrons injection from the cathode by an attractive Coulomb force to effectively increase the mobility of the electrons while blocking high-mobility holes from the anode at an interface between the light-emitting layer and the water-soluble layer. Further provided is a method for fabricating the electroluminescent device.

Abstract: A process for increasing the hydrogenation activity, particularly the carbon monoxide hydrogenation activity, of a catalyst or catalyst precursor comprised of a particulate solids support component and a catalytic metal, or metals component, preferably cobalt; cobalt alone or cobalt and an additional metal, or metals added to promote or modify the reaction produced by the cobalt. Treatment of the catalyst, or catalyst precursor is conducted at low temperature ranging from ambient to about 275° C. sufficient to form on the surface of a catalyst precursor, e.g., a cobalt catalyst precursor, a cobalt metal hydroxide, low valence cobalt metal oxide, or mixture of cobalt metal hydroxide and low valence cobalt metal oxide. Sometimes also metallic metal, e.g., cobalt, is also formed, and dispersed on the surface of the support.

Abstract: A catalyst precursor comprising a composite of a solids support, or powder component, and a compound or salt of a metal, or metals component, inclusive of cobalt, is upon reduction rendered catalytically active for conducting hydrogenation reactions, especially carbon monoxide hydrogenation reactions by contact at low temperature with liquid water, or steam, or a mixture of liquid water and steam, sufficient to oxidize and convert the metal, or metals component of the catalyst precursor to a metal hydroxide, low oxygen-containing metal oxide, or mixture of metal hydroxide and low oxygen-containing metal oxide. On reduction, as may be produced by contact and treatment of the oxidized catalyst precursor with hydrogen, the now well dispersed oxide or hydroxylated catalytic metal, or metals component of the catalyst, is reduced to metallic metal, e.g., Co, and the catalyst thereby activated.
