The review considers the environmental problem of generation, accumulation and utilization of waste tires in Ukraine and the world. It is established that waste tires can serve as a valuable raw material for obtaining fuel components and technical/individual chemicals for further industrial processing. One of the promising methods for the rational utilization of waste tires may be their pyrolysis. The pyrolysis process of waste tires produces gaseous, liquid and solid carbonized residue. At the same time, there is no ideal universal technology for the use of waste tire pyrolysis products without preliminary treatment/purification methods. The main characteristics, processing methods and applications of products obtained from the pyrolysis of waste tires are briefly considered.

Herein, a method for the coke dry quenching (CDQ) process has been proposed and its optimization has been carried out, which will minimize the disadvantages of this process. This optimization was carried out to develop a technology for uniform coke distribution in the quenching chamber. A model of the real charging device for quenching coke from the Ukrainian enterprise PrJSC “Avdiivka Coke” was developed, and several shortcomings of its operation were shown. It is proposed to use a coke distributor in the form of a bell and a modified bell (specially shaped holes). Graphic mathematical models of the operation of these two devices were developed, and the efficiency of the last of the developed distributors was shown.
