RUBBER WASTE RECYCLING METHOD Russian patent published in 2001 - IPC

FIELD: chemical industry; rubber industry. SUBSTANCE: proposed invention can be used in chemical industry for production of adsorbents, in rubber industry for production of ingradients for rubber mixtures and fuel energy-producing complex for utilization of waste. According to proposed method, rubber waste is subjected to thermal decomposition in steam-gas medium, and products of decomposition are separated, solid ones are separated from gaseous ones. Solid products of decomposition are into activation furnace into which water steam in amount of 0.8 - 1.6 kg per of solid products is added. Gaseous mixture from activation furnace is discharged at mass ratio of water steam and activation gases in mixture of (3-0.6):1, and it is used steam-gas medium for thermal decomposition of waste. EFFECT: reduced amount of harmful gaseous effluents in process of waste recycling. 2 cl, 1 dwg
