  • Method for preparing carbon black from pyrolysis char of waste tires by molten salt thermal treatment and product thereof
    Patent number: 11926742
    Abstract: A method for preparing carbon black from pyrolysis char of waste tires by a molten salt thermal treatment and a product thereof are provided. The method includes heating one or two groups of a metal chloride salt group and a metal sulfate group to obtain a molten salt; adding pyrolysis char of waste tires into the molten salt and subjecting same to a molten salt thermal treatment under a preset reaction atmosphere; after the reaction is complete, separating the reaction product to obtain a secondary molten salt and treated pyrolysis char, washing the treated pyrolysis char with hot water and then drying same so as to obtain carbon black, and at the same time, recycling the secondary molten salt.
    Type: Grant
