Abstract
En 中文
The innovative recycling of waste tires into fuel is essential for promoting sustainable development, enhancing waste valorization, and advancing waste-to-energy technologies. For the processing of fr. <= 200 degrees C, separated from the liquid products of the pyrolysis process of waste tires, polycondensation with formaldehyde and extraction with a polar solvent (N-methyl-2-pyrrolidone) was used. Due to the sequential application of these processes, a raffinate product is produced that contains significantly fewer undesirable compounds, such as reactive unsaturated hydrocarbons and aromatics, which can negatively affect gasoline. Additionally, this raffinate demonstrates chemical stability during storage. Due to its operational properties, the obtained raffinate can serve as a high-quality component for gasoline production, which is advisable when mixed with low-octane gas condensate. As a result of compounding, Euro 4 gasoline is obtained with an octane number equal to 93 according to the experimental method. The possibility of effectively using the extract (concentrate of aromatic and unsaturated compounds) as a plasticizer for waterproofing mastic was shown. Overall, the valorization of waste tire pyrolysis processing contributes to waste reduction and is consistent with promoting sustainable industrial innovation by replacing primary petrochemical feedstocks with secondary feedstocks and supporting the development of alternative energy sources.
