The amount plastic waste is increasing which results in a chronic problem to the environment. There is many efforts to reduce as well as reuse the plastic waste. In this project, we investigate about the use of pyrolysis of plastic waste to produce fuel oil. For example, Plastic carrier bags, considered a low-density polyethylene (LDPE), can be used as raw material for the production. A commercial natural zeolite namely magnesium carbonate is to be used as a catalyst to enhance the oil conversion. We use approximately two kilogram of plastic waste is crushed will be loaded into the reactor chamber for pyrolysis process. For obtaining liquid fuel from pyrolysis process a fixed bed pyrolysis system has been designed and fabricated. The major components of the system are: fixed bed reactor, fractionating cylinder and liquid condenser. A 6 inch diameter and 2 feet high fixed bed reactor is used to pyrolized externally heating the small sized LDPE. The reactor is heated by means of a LPG source. The production of pyrolysis fuel from waste polyethylene leads to production of large amount of gaseous product, some of them are non- condensable at room temperature. The gaseous products can serve as feedstock and as fuel gas.

Keywords : pyrolysis, waste plastics, reaction chamber, fabrication cylinder, condenser, pyrolysis fuel and fuel properties.
