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.

摘要： The present invention pertains to a process for activating a catalyst composition comprising at least one hydrogenation metal component of Group VI and/or Group VIII of the Periodic Table, and an S-containing organic additive, wherein the catalyst is contacted with hydrogen at a temperature between room temperature and about 600° C., preferably about 100-450° C., and prior to or during the contacting with hydrogen the catalyst is contacted with an organic liquid. Preferably, the contacting with the organic liquid is carried out prior to the contacting with hydrogen. The organic liquid may be a hydrocarbon with a boiling range of 150-500° C., preferably white oil, gasoline, diesel, or gas oil or mineral lube oil. It was found that the application of an organic liquid prior to or during the hydrogen treatment results in catalysts with an increased activity. The invention also comprises catalyst made by the above process and the use of such catalyst in hydrotreating.

摘要： The process has as an object the regeneration of catalysts containing at least one contaminating metal of the vanadium, nickel and iron group. The operation is conducted as follows:(a) The catalyst (1) is roasted in the presence of an oxygen-containing gas so as to remove at least 90% of the sulfur;(b) The catalyst obtained in step (a) is contacted with a hydrogen peroxide aqueous solution containing at least one organic compound comprising an acidic functional group, so as to remove at least 10% of the deposited metals of the vanadium, nickel and iron group; and(c) The regenerated catalyst (11) is separated from the aqueous solution of metal ions (5). The latter can be regenerated by passage over a complexing resin (6).The process is applicable to the regeneration of used catalysts, particularly to hydrotreatment catalysts in the oil industry.
