چکیده

Tire recycling or tire recycling is a process in which car tires are no longer worn out or are no longer suitable for use because of a rupture or unrepairable failure. These tires are among the most significant waste that is very problematic. This problem is due to the persistence and persistence of tires and their high volume of production. It is estimated that 259 million tires are discarded each year. In this research, the Preparation stages of production of activated carbon nanofibers produced from the recycling of worn tire rubber with different percentages of different solvents of potassium hydroxide, ethanol, and toluene were studied and tested. To achieve a solution for worn tire tires, a certain amount of scraped rubber fragments was dissolved in potassium hydroxide, ethanol, and toluene solvents, and electrospinning solutions were determined and prepared and to produce nanofiber layers, Electrospinning operations are performed. By scanning electron microscopy images, the mean diameter of nanofibers obtained in potassium hydroxide solvent was the lowest, and scanning electron microscopy images confirmed the absence of willow in the produced nanofibers. The efficiency of carbon production was determined as 37.2%. To confirm the formation of activated carbon, FTIR spectra were used, which confirmed the presence of spike related to the aromatic ring formation of activated carbon nanofibers after activation.
