The present invention concerns a moving bed catalyst regenerator (1) comprising a vessel (2) extending in a vertical direction, said vessel being divided into at least two regeneration zones extending along the vertical height of said vessel, in which particles of catalyst move under gravity, the regenerator being configured such that each regeneration zone is capable of separately regenerating a different composition of catalyst and in which each regeneration zone comprises, in succession and in the order in which the catalysts move: a) a combustion section (CO); b) an oxychlorination section (O) disposed below the combustion section and comprising means for bringing catalyst from the combustion section (CO) to the oxychlorination section (O); c) a calcining section (CA) disposed below the oxychlorination section.

An integrated process and associated system for naphtha reforming and benzyl toluene production. The process includes providing a first toluene stream and a chlorine gas stream to a halogenation reactor to generate a benzyl chloride stream and a first HCl effluent stream then providing the benzyl chloride stream, a second toluene stream, and a Lewis acid stream to an alkylation reactor to generate a benzyl toluene stream and a second HCl effluent stream through a Friedel-Crafts reaction. The process further includes providing naphtha to a catalytic reforming unit to generate a reformate stream and a spent catalyst stream and then providing the spent catalyst stream and at least one of the first HCl effluent stream and the second HCl effluent stream to a catalyst regenerator to regenerate the spent catalyst stream.
