The mechanism of "Activated Clay Treatment" in the refining process of BTX was studied with toluene containing with heptene-2 or 1, 3-pentadiene.
As the results, it was confirmed that the polymerization of olefines took place when the olefins were percolated through clay. In other words, the clay obviously acts as a solid acid catalyst for polymerization of olefines in the course of refining of BTX. This catalytic ability is influenced by adsorbed water on the clay at low temperature.
