We studied the disproportionation reaction of BTX in the refining process and found that the disproportionation of xylene took place when the xylene was percolated through activated clay. This disproportionation reaction is generally found with many kinds of clays which are commercially available. Using the Alumina poor clay, olefines were polymerized but the disproportionation of xylene did not take place at the same conditions.
