Refining of Mixed Plastic Waste to Produce Low Pour Point Diesel Fuel

The possibility of obtaining low pour point diesel fuel by dewaxing of feedstock containing hydrotreated thermolysis oil obtained from a mixture of plastic wastes is presented. It has been established that in the process of dewaxing the n-alkanes of the feedstock, regardless of the length of the carbon chain, undergo almost complete conversion, leading to the improved low-temperature and rheological properties of the hydrotreated product. It is concluded that the obtained petroleum products are characterized by a high degree of environmental purity, since they do not contain chlorine, and the concentration of sulfur- and nitrogen-containing compounds, as well as polycyclic aromatic hydrocarbons, is minimal.
