Pyrolytic Decomposition of Polyethylene in the Presence of Aluminosilicate Materials Containing Nickel Oxide
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.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
