Zeolites were synthesized from fly ash and used as catalysts for pyrolysis of polypropylene(PP). Zeolite synthesis was carried out by fusion methods employing three different NaOH/Fly ash ratios in weight. The catalytic performance of the fly ash-derived zeolite was assessed in terms of the yield and simulated boling point distribution of the liquid pyrolysis products. The properties of the fly ash-derived zeolites were characterized by XRD, SEM, BET, NH₃-TPD. It was found that the optimum NaOH/fly ash weight ratio was 1.2 in terms of the simulated boiling point distribution. The catalytic performance of the fly ash-derived zeolite was significantly improved by ion exchanging of zeolite from Na form(FAZ) to H form(HFAZ). The boiling point distributions of liquid pyrolysis products obtained over HFAZ were significantly lower than that obtained zeolite.
