FIELD: chemistry.
SUBSTANCE: invention relates to a benzene alkylation method which includes: A) obtaining at least a portion of a stream from a transalkylation area; B) combining said at least portion of a stream from a transalkylation area with a fuel gas stream containing an alkylation-effective amount of one or more alkanes which is obtained at least in part from the tail gas of a hydrogen purification process; C) feeding at least a portion of said combined stream into a benzene methylation area. The output stream from the transalkylation area is fed into a stripping area, wherein said at least portion of the stream from the transalkylation area is obtained from said stripping area.
EFFECT: method provides more flexible use of material.
