Catalytic cracking in the presence of guaiacol

▶ When gasoil is cracked at 535 °C in the presence of guaiacol, overall conversion increases. ▶ An increase in benzene, toluene and xylene (BTX) was observed in the presence of guaiacol. ▶ At constant conversion, the ZSM-5 additive reduces the xylene yield without affecting benzene and toluene.
