LDPE was converted to a mixed of lower and higher hydrocarbons over Co-ZSM-5. One-pass reactor in a temperature range of 400-500°C and atmospheric pressure was employed. We observed the complete conversion of LDPE, in the range of temperatures studied. The catalysts were characterized by several physicochemical techniques: XRD, FTIR, Surface area (BET) and AA. The feed was analyzed by FTIR and thermal analysis TG-DSC. Reaction products were studied by gas chromatographic and gas chromatography/mass spectrometry. By means of the development of a competitive catalytic system, we determine the feasibility of the process of degradation of LDPE remainders towards the synthesis of gaseous and liquid HC.
