Oil and gas production from the pyrolytic transformation of recycled plastic waste: An integral study by polymer families
نویسندگان
چکیده
Different plastics recovered from a local urban solid waste plant were collected before landfilling, separated, and classified by families, i.e. polyethylene (PE), polypropylene (PP), high impact expanded polystyrene (HIPS EPS, respectively), terephthalate (PET), polyvinyl chloride (PVC). A systematic pyrolysis study was carried out to compare the different behavior registered in each plastic type, an integral analysis of produced oils synthetic gas conducted. In general terms, oil yield followed order EPS > PP PE HIPS PET PVC, reaching maximum values over 500 °C after 1 h treatment. The HIPS, PET, rich light compounds, i.e., C5-C9 hydrocarbons. Almost 100 % aromatic. aromatic fraction important case PVC (57 %) (45 %). with most varied distribution compounds but olefins (67 non-condensable composition showed that all gases methane 50 (vol.), ethane importance. CO PET.

Pyrolytic Waste Plastic Oil and Its Diesel Blend: Fuel Characterization
The authors introduced waste plastic pyrolysis oil (WPPO) as an alternative fuel characterized in detail and compared with conventional diesel. High density polyethylene, HDPE, was pyrolyzed in a self-designed stainless steel laboratory reactor to produce useful fuel products. HDPE waste was completely pyrolyzed at 330-490°C for 2-3 hours to obtain solid residue, liquid fuel oil, and flammable ...

Besides the second generations bio fuels, one of the most promising products is the bio gas oil, which is a high iso-paraffin containing fuel, which could be produced by the catalytic hydrogenation of different triglycerides. To broaden the feedstock of the bio gas oil the catalytic hydrogenation of waste lard over sulphided NiMo/Al(2)O(3) catalyst, and as the second step, the isomerization of ...
