Abstract: A process for producing phenol is described in which a feed comprising alkylbenzene hydroperoxide is contacted with a cleavage catalyst under cleavage conditions effective to convert at least part of the hydroperoxide into phenol, the process is characterized in that at least a part of the deactivated catalyst is regenerated using a oxidizing material comprising hydrogen peroxide and then return to the process. A method of regenerating the cleavage catalyst is also described.
