Pyrolysis oil production from municipal polyethylene (pe) plastic waste
The world is full of plastics. However, plastics are not biodegradable and are rather difficult to be decomposed in the environment. The buildup of huge amount of plastic waste in landfills have become a global concern, hence, a solution needs to be found. One possible solution is by recycling with thermal decomposition, namely pyrolysis. Pyrolysis is a thermal process that converts plastic back into petroleum. To assist the pyrolysis process, several catalysts were used in this research as well, these catalysts are the active carbon and activated bentonite clay. Bentonite clay was activated by thermal activation at 500oC for two hours in a furnace. Catalysts affected the product generated as well as the properties of the product, with activated bentonite clay beingrnthe more effective catalyst rather than active carbon. Nevertheless, the product generated are still in the crude condition. However, the addition of activated bentonite clay successfully increased the product yield and removed the contaminant in the product, although the product appeared to be more waxy and solid in room temperature. The contaminants present in the pyrolysis product are the aromatic hydrocarbons and vinyl olefins, however, clay could remove the aromatic hydrocarbons but not the vinyl olefins. Hence, a further refining process needed to be done for further research.
