Upgrading of Scrap Tyres

Target

• Disposal of scrap tires
• Production of a high quality condensates for bitumina and chemical industries
• Production of industrial carbon black; best case substitution of rubber carbon black -> but there are still needed international standards for high quality levels

Products Permanent gas: for process heating Condensate oil: heating value up to 44 MJ/kg Condensate water: low amount Solids: industrial carbon black typically 80-85% C, rest are fillers

Advantages DGE Basic Technology

• continuous process for highest quality and stability
• no critical emissions
• electrical heat -> minimum of emissions & minimum of heat losses
• combination with renewable energy
• process open for sidestream technologies (catalysts, ultrasonic, microwaves)

Needed Pre Treatment

Drying: not needed Pre-Crushing: 250x250mm is possible, 20x20mm typical - but smaller pieces increasing the throughput Granulation to 1mm grain Sorting: metall separation (non tempered scrap metall gives higher prices)

Post Treatment

• Activation
• Milling down to µ-particles
• Pelleting / briquetting
• Fractioning of the oil
