Abstract: Methods for resin hydrogenation and decoloration may comprise reacting a resin mixture with a sulfided bimetallic catalyst and excess hydrogen under conditions effective to form a hydrogenated resin mixture, the resin mixture comprising an oligomerized reaction product of at least one polymerizable monomer containing an olefinic unsaturation and a solvent; providing the hydrogenated resin mixture directly to a noble metal catalyst; and reacting the hydrogenated resin mixture in the presence of the noble metal catalyst under conditions effective to form a decolorized resin mixture. Decolorized resin compositions comprising a decolorized resin mixture formed in accordance with the foregoing may have a yellowness index of about 10 or below, as measured by ASTM E313.

Abstract: Disclosed are novel processes for making cyclohexanone compositions, from a mixture comprising phenol, cyclohexanone, and cyclohexylbenzene. The process includes hydrogenation of a feed stream comprising phenol, cyclohexanone, and cyclohexylbenzene. The feed stream may be subjected to one or more pre-hydrogenation treatments, such as passing through one or more sorbents, addition of basic chemical agents, and/or addition of water, so as to improve catalyst activity, minimize undesired side reactions, and/or remove catalyst poisons from the feed stream. The feed stream may be provided to a hydrogenation reaction zone in the vapor phase, with periodic alterations to hydrogenation reaction conditions such that the feed is provided in mixed liquid and vapor phase in order to carry out liquid washing of a hydrogenation catalyst bed within the hydrogenation reaction zone.

Abstract: A thermal neutron detector and method employ Gd-containing nanoscintillators. Thermal neutron radiation is detected by observing scintillation events from the nanoscintillators.

Abstract: High strength presulfided catalyst for hydrogenating hydrocarbon resins without an in situ sulfiding step. The catalyst particles have a supported metal catalyst structure with presulfided interstitial surfaces with about 20 weight percent of a low molecular weight hydrocarbon resin, based on the weight of the porous supported metal catalyst structure, filling from 90 to 95 percent of the pore volume to improve a crush strength of the catalyst particles. The presulfided catalyst can be stored and/or shipped in an airtight container with an inert atmosphere. The catalyst particles are made by preparing the oxidized catalyst, presulfiding the catalyst, contacting the catalyst with the low molecular weight hydrocarbon resin in an inert atmosphere, sealing the catalyst in a storage/shipping container, loading the reactor with the presulfided, filled catalyst, and contacting the catalyst with an unsaturated hydrocarbon resin under hydrogenation conditions.

Abstract: A process for forming acids from aldehydes which comprises reacting an oxo aldehyde with water in the presence of an acid-forming catalyst and in the absence of hydrogen, and at a pressure of about 0.1 to 6.99 MPa and a temperature of about 93.degree. to 205.degree. C., thereby converting aldehyde to an oxo acid.

Abstract: The hydrogenation steps and hydrofinishing steps of the cobalt catalyst oxo process for preparation of the alcohols by the hydroformylation of olefin are carried out using a catalyst containing Ni/Mo on alumina or silica alumina prepared by depositing an organic acid solution of Ni and Mo salts on the support, the acid being phosphorous free.

Abstract: The hydrogenation steps and hydrofinishing steps of the cobalt catalyst oxo process for preparation of the alcohols by the hydroformylation of olefin are carried out using a nickel-molybdenum catalyst on an alumina or silica alumina support which has a phosphorous content of O.1 wt. % to 1.0 wt. % phosphorus.

Abstract: The hydrogenation steps and hydrofinishing steps of the cobalt catalyst oxo process for the preparation of alcohols by the hydroformylation of olefin are carried out using a trimetallic catalyst composed of metal oxides, particularly nickel oxide, molybdenum oxide and cobalt oxide supported on alumina or an alumina-silica in sulfided and non-sulfided form.

Abstract: A vertical fabric vane weight system is used to interconnect a plurality of fabric vanes. The vertical vanes are secured at their top end to a head rail and the botton ends are freely movable. An enclosed pocket is formed adjacent to the bottom of each vertical vane, each vane having a weight positioned in its respective pocket. A continuous chain member interconnects the weights along one edge of the vanes. Clips are used to interconnect the continuous chain to each of the weights and are removable should the chain not be a desirable feature.

Abstract: Synthesis gas is produced by the reaction of light hydrocarbons, primarily methane, in a fluid bed reaction zone of attrition resistant nickel on alpha-alumina catalyst, with steam and oxygen and the conversion level is preserved by limiting the loss of nickel from the reaction and thereby limiting the back reaction of the synthesis gas to form methane in the presence of entrained catalyst in a cooling zone.
