Abstract:
1. A process, comprising: feeding a reactant stream E comprising a C converting reactant stream E under nonoxidative conditions in the presence of a particulate catalyst into a product stream P, comprising an aromatic hydrocarbon, discharging product stream P from reaction zone 1, transferring the catalyst into a reaction zone 2, the catalyst having reduced activity as a result of deposited coke, at least partly regenerating the catalyst with a supply of a hydrogen-comprising gas stream H in a reaction zone 2, thereby converting at least some of the coke deposited into methane to form a methane-comprising gas stream M, feeding the gas stream M at least partly to reaction zone 1, discharging the catalyst from reaction zone 2, to obtain a discharged catalyst, and recycling at least a portion of the discharged catalyst into reaction zone 1, wherein reaction zone 1 and reaction zone 2 are adjacent to one another in a reactor and wherein essentially no gas backmixing occurs between reaction zone 1 and reaction zone 2.
