Patent ID: 7317132

Claim:
Method for utilization of rubber wastes with simultaneous performance of pyrolysis of coal in cells of a coke oven battery, in which each cell is filled with a previously prepared and disintegrated blend of coking coals, comprising the steps of: adding a rubber granulate in the form of a rubber grain of a size of particles 0.1-5.0 mm in an amount of 1-5% by weight, to each charge of the blend of coking coals of a size of particles 0.1-5.0 mm in an amount of 95-99% by weight in each cell of the coke oven battery with a gravitational charge filling system for filling particles having a size between 0.1 and 20.0 mm; thickening a composition of the coking coals and the rubber grain formed by said step of adding, by mechanical compacting until a uniform structure of a whole charge is obtained; and performing a process for utilization of rubber wastes in a closed system without access to oxygen, at a temperature of at least 900° C. with a simultaneous pyrolysis of coal.
