(57) [Abstract] A method for alkylating benzene contained in a refinery mixed stream is disclosed. According to this method, first, a refinery stream (2) is hydrogenated with higher olefins ( After the treatment in 14), benzene is alkylated with the selected type and amount of the lower olefin (1). Streams containing sulfur compounds can be pretreated by hydrodesulfurization. To take advantage of such a mode of operation, it is advantageous to carry out all of the process steps in the distillation column reactor (10). |
