Abstract
A process for the conversion of heavy bottoms from aromatic alkylation known as "flux oil" and containing heavier polyalkylaromatic compounds, in which the heavier polyalkylates are fed along with aromatic to a reactor containing an acidic zeolite catalyst for conversion to light mono-, and poly alkylaromatic compounds. The light polyalkylates may then be transalkylated with benzene to form additional monoalkylate.
