The main constituentsof liquid pyrolysates are 1-n-alkenes, n-alkanes and terminal n-dienes. Thecomposition of liquid products indicates that the performed pyrolysis of HDPEcould not serve as a standalone operation for the production of gasoline ordiesel, but preferably as a pre-treatment to yield a product to be blended into arefinery or petrochemical feed stream. The advantage of a liquid pyrolysate incomparison to crude oil is the extremely low content of aromatic hydrocarbonsand the absence of polar compounds. The gaseous products have desirablecomposition and consist mainly of methane and ethene. The solid residues donot produce ash by combustion and have high calorific values. Co-pyrolysis ofHDPE with mineral-rich lignite indicated positive synergetic effect at 450 and500 °C, which is reflected through the increased experimental yields of liquidand gaseous products in comparison to theoretical ones.",
