Study on Regularities of Polyethylene Waste Low-Temperature Pyrolysis
AI summary Read the abstract
Researchers studied the low-temperature pyrolysis of polyethylene waste to characterize the fractional composition and properties of the resulting pyrocondensate at varying temperatures and reaction times. X-ray fluorescence analysis revealed the composition of the gasoline, diesel, and residual fractions, establishing relationships between pyrolysis conditions and product properties relevant to plastic waste recycling.
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.
