polyethylene waste

A low-temperature pyrolysis with pyrocondensate as a target product is one of the options for processing polyethylene waste. The fractional composition and properties of the pyrocondensate obtained at different temperatures and times were studied. Pyrocondensate was separated into gasoline, diesel fractions, and the residue. The composition and properties of mentioned fractions were established and related to the conditions of the pyrolysis process. X-ray fluorescence analysis of pyrocondensate and narrow fractions isolated from it was carried out.

One of the options for utilization of polyethylene waste is low-temperature pyrolysis, the target product of which is pyrocondensate. In the work, the fractional composition and properties of the pyrocondensate of pyrolysis of polyethylene waste were studied. It was established that pyrocondensate and its fractions practically do not contain heavy metals characteristic of oil fractions. Pyrocondensate is divided into gasoline, diesel fraction and residue. The composition and properties of these fractions were studied in detail.
