Low-density polyethylene (LDPE) was converted to light hydrocarbons and aromatic hydrocarbons over H-, Zn- and Ga-containing MEL and BEA zeolites, using a one-pass reactor in the temperature range 420–500°C with WHSV= 1-5h−1 and employing an appropriate solvent for the feed. The catalysts were synthesized by the sol-gel technique and characterized by FTIR. The acid properties of the catalysts were investigated by FTIR of pyridine as a probe molecule desorbed to vacuum at different temperatures and by temperature-programmed ammonia desorption (TPAD) of NH4- zeolites. The ratilationship between of the nature of the active sites and the products distribution is also discussed. ratilationship between of the nature of the active sites and the products distribution is also discussed. appropriate solvent for the feed.
