  • Patent number: 10259765
    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.

  • Publication number: 20130184411
    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.

  • Patent number: 5663388
    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.

  • Patent number: 5094287
    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.

  • Patent number: 4888131
    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.
