ABSTRACT

This study aims to investigate the thermal and catalytic pyrolysis of crushed instant noodle packs (CINP) and crushed coffee sachets (CCS) with and without calcined- natural zeolite catalysts. The experimental works were conducted using a small scale vertical tubular reactor heated by an electrical heater. The thermal pyrolysis experiments were carried out at the reactor temperature of 400, 450, and 500℃. In the second experiments, catalyst was loaded on the upper side of the reactor at various catalyst to plastic ratio. The results show that CINP produced higher liquid product at lower temperature while CCS produced higher liquid product at higher temperature. The maximum liquid oil yield obtained up to 65% on CCS pyrolysis at the temperature of 500℃. The presence of catalyst reduced the liquid fraction for both feedstocks and modified the chemical composition of the pyrolytic oil. The heating value of the pyrolytic oil was high enough for fueling the engine and other external combustion engines. CCS pyrolysis also produced much more solid product compared to CINP.
