摘要:
The present invention relates to a process for nonoxidatively dehydroaromatizing a reactant stream comprising C1-C4-aliphatics, comprising the steps of I. feeding reactant stream E into a reaction zone 1, converting reactant stream E under nonoxidative conditions in the presence of a particulate catalyst to a product stream P comprising aromatic hydrocarbons and discharging product stream P from reaction zone 1, II. transferring the catalyst with reduced activity as a result of deposited coke into a reaction zone 2, III. at least partly regenerating the catalyst with supply of a hydrogen-comprising gas stream H in a reaction zone 2, at least some of the coke deposited being converted to methane to form a methane-comprising gas stream M which is fed at least partly to reaction zone 1, IV. discharging the catalyst from reaction zone 2 and V. recycling at least a portion of the discharged catalyst into reaction zone 1, reaction zone 1 and reaction zone 2 being arranged spatially adjacent to one another in the same reactor.
