Pyrolysis of high-density polyethylene in the presence of aluminosilicate materials containing nickel oxide has been studied. The catalytic pyrolysis of plastics makes it possible to convert polymers into chemical compounds, which can later be used as additional sources of fuels and raw materials for chemical industry or polymer production. The physicochemical parameters of the materials containing nickel oxide were determined by Fourier-transform IR spectroscopy, X-ray diffraction analysis, N2 physical adsorption method, thermogravimetric analysis, and pyrolytic gas chromatography. The chemical composition of polyethylene pyrolysis products was found to depend on the type of support used and the presence of nickel oxide in it. The presence of nickel oxide in the studied aluminosilicates increases the Lewis acidity and the content of aromatic compounds in the pyrolysis products. The activation energy of polyethylene pyrolysis in the presence of MSM-41 containing nickel oxide was calculated from the experimental data.
