In this work, ZSM-5, a size selective heterogeneous catalyst was employed for the synthesis of p-xylen from durene by cracking. The reaction was carried out in gas phase using a fix bed reactor. During the reaction, benzene was used as solvent together with durene. To optimize the reaction conditions, temperature, feed ratio, feed flow rate, reaction time and catalyst load weight were investigated. The products were analyzed by gas chromatography (GC). The selectivity of p-xylene and the conversion of durene was 20.04% and 40.09% respectively when the reaction was carried out at 450 ˚C for 1 h using 1.0 g catalyst with feed ratio 1: 8 and flow rate 2.0 ml/h.
