What are the uses of carbon black from tire pyrolysis?

 Carbon black produced by tire pyrolysis has a variety of uses, which are mainly based on the physical and chemical properties of carbon black. The following is a detailed summary of the main uses of tire pyrolysis carbon black:

1. As a solid fuel: Tire pyrolysis carbon can be used directly as a solid fuel, and its combustion value is high, which is suitable for industrial heating and other scenarios.

2. Reinforcement filler for rubber products: Carbon black is added as a filler during the tire manufacturing process. After the waste tire is pyrolyzed, carbon black remains in the pyrolysis carbon. Although the quality is lower than that of commercial carbon black, after modification (such as acid washing), the tensile strength, tear strength and wear resistance of pyrolysis carbon can be improved, thereby replacing commercial semi-reinforcement carbon black for the production of rubber products such as tires and rubber soles.

3. Preparation of activated carbon: Pyrolysis carbon has a porous structure and can be used as activated carbon after activation modification. This activated carbon shows high efficiency in adsorbing heavy metals and macromolecular substances, and is a low-cost and efficient adsorbent.

4. Catalyst or catalyst carrier: The pore structure of pyrolytic carbon can not only be used to adsorb pyrolytic oil molecules, but also as a place for catalytic reactions, so it can be used to prepare catalysts or as a catalyst carrier.

5. Asphalt modifier: The surface polarity of pyrolytic carbon is low, it is easy to disperse in asphalt, and it can be firmly combined with the asphalt matrix, thereby achieving the purpose of reinforcing asphalt. Asphalt with added pyrolytic carbon will have significant improvements in anti-rutting, elastic recovery, heat resistance, light resistance and anti-aging properties.

6. Pigment carbon black in the field of ink: The main components of ink are fillers, pigment carbon black, adhesive materials and auxiliary additives. Although the ash content of waste tire pyrolytic carbon is high, which affects its effect as pigment carbon black, it can be used in printing ink instead of industrial low-pigment carbon black after modification (such as nitric acid acid elution deashing + tantalum ester coupling agent grafting modification).

7. Electrode materials: Waste tire pyrolytic carbon can also be used to prepare electrode materials. This electrode material has good electrochemical properties, such as high initial specific capacitance, long cycle life, low equivalent series resistance and short relaxation time, and is suitable for electronic devices such as supercapacitors.

In addition, tire pyrolytic carbon black can also be sold directly or further processed into different types of semi-reinforced carbon black for use in tire manufacturing, rubber products, inks, coatings, and plastic additives. These uses not only enhance the utilization value of tire pyrolytic carbon black, but also help solve the environmental problems caused by the accumulation of waste tires and realize the recycling of resources.

In general, tire pyrolytic carbon black has a wide range of application prospects. The persity of its uses and the increase in market demand will further enhance the economic efficiency of the waste tire pyrolysis recycling process.
