Abstract: | The economic success of feedstock recycling procedures for plastic wastes is increasingly demanding the conversion of the
starting residue into more valuable chemicals. Thermal cracking of polyethylenes leads to the preparation of equimolar mixtures
of n-paraffins and 1-alkenes within the C2–C100 range. These 1-olefins can be catalytically upgraded by selective oxidation processes to more valuable products (e.g., ketones
and fatty acids) with different uses such as polar waxes, cetane improvers, varnishes, and printer inks. The results obtained
on oxidation in a modified Wacker system of a model 1-olefin (1-dodecene) as well as of a distillate cut (C10–C25) of the product from the thermal cracking of urban polyethylene waste are described. |
