    摘要: Disclosed herein is a process for producing phenol. The process includes oxidizing at least a portion of a feed comprising cyclohexylbenzene to produce an oxidation composition comprising cyclohexyl-1-phenyl-1-hydroperoxide. The oxidation composition may then be cleaved in the presence of an acid catalyst to produce a cleavage reaction mixture comprising the acid catalyst, phenol and cyclohexanone. At least a portion of the cleavage reaction mixture may be neutralized with a basic material to form a treated cleavage reaction mixture. In various embodiments, the cleavage reaction mixture contains 1 wt % to 30 wt % phenol, 1 wt % to 30 wt % cyclohexanone and a complexation product.

    摘要: This invention is directed to controlling regenerator temperature in an oxygenate to olefin process. Because a significant amount of heat can produced in the regenerator during the regeneration process, at least a portion of the heat must be removed to keep the system from getting too hot. This invention removes heat during the regeneration of the catalyst, using appropriate circulation of catalyst between the reactor and the regenerator. Sufficient circulation can eliminate the need for the use of a catalyst cooler in the regeneration system.
