Výroba syntézního plynu pomocí suchého reformování plynných uhlovodíků z termokatalytické pyrolýzy odpadních polyolefinů

Abstract

This thesis deals with the thermocatalytic transformation of waste polypropylene to aromatic hydrocarbons and synthesis gas via multi-stage catalytic process. A zeolite catalyst TZM-25 was used for the catalytic pyrolysis, which provides a better pyrolysis oil with a high content of aromatic hydrocarbons (mainly BTEX). In the next step, the pyrolysis gas was treated by dry reforming using prepared nickel catalysts with defined nickel content on alumina. Optimization of the reaction conditions was carried out at 800, 700, 650 and 600 °C. The best results were obtained at 800 °C where the highest conversion was achieved. The results of this work represent a contribution to the field of plastics recycling and, especially through the use of CO2, to the decarbonization of the chemical and petrochemical industries.
