摘要： A method for disposing of a mixture of oxidizable catalyst material and inert support media. The method comprises introducing inert gas into an enclosure. The enclosure contains a plurality of stacked screens, the stacked screens have openings that decrease in size from a top of the stack to a bottom of the stack. The method also comprises introducing the mixture to an uppermost one of the plurality of stacked screens; moving the plurality of stacked screens to cause the oxidizable catalyst material to separate from and migrate to a location beneath the inert support media; conveying the separated inert support media to a location outside the enclosure for disposal as non-hazardous waste; and conveying the separated oxidizable catalyst material to a location outside the enclosure for at least one of reclamation, or thermal destruction.

摘要： A process for the fluorination of a chlorinated C3 alkane or alkene compound having at least one chlorine atom into a fluorinated C3 alkane or alkene compound having at least one fluorine atom includes the following steps: a) contacting, in a reactor, the chlorinated compound with hydrogen fluoride in gas phase in the presence of a fluorination catalyst to produce a fluorinated compound, and b) regenerating the fluorination catalyst used in step a). The step (b) of regenerating the fluorination catalyst comprises (c) the treatment of said fluorination catalyst with an oxidizing agent-containing gas flow to form an oxidized fluorination catalyst, and (d) the treatment of the oxidized fluorination catalyst obtained in step (c) with a gaseous mixture comprising a reducing agent and an inert gas. The catalyst regenerated in step b) is reused in step a) and the reducing agent is selected from C1-C10 hydrohalocarbons.

摘要： Methods for regenerating a spent catalyst are disclosed. Such methods may employ a step of chlorinating the spent catalyst in the gas phase, followed by decoking the chlorinated spent catalyst, and then fluorinating the de-coked catalyst in a fluorine-containing solution of a fluorine-containing compound.

摘要： 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.
