METHOD FOR PREPARING STYRENE AND BENZENE

摘要

The present invention relates to a method for producing styrene and benzene, wherein a raw material stream is supplied to a C6 separation column, an upper discharge stream of the C6 separation column is supplied to a hydrodesulfurization process unit, and a lower discharge stream is supplied to a C7 separation column; Supplying an upper discharge stream from the C7 separation column to a dialkylation reaction unit, and supplying a lower discharge stream to a C8 separation column; Recovering styrene from the C8 separation column overhead stream; And recovering benzene from the stream discharged from the hydrodesulfurization process unit and the dialkylation reaction unit.
