<Session> Advanced Pyrolysis: Tire Pyrolysis Oil (TPO) & Byproduct Utilization
Novel Step Pyrolysis Technology for Recovery Valuable Products from Waste Tires
The black pollution caused by waste tires has attracted extensive attention all over the world in recent years. According to statistics, about 1.5 billion units of waste tires were produced annually, which gave rise to around 17 million tons. Owing to the stable molecular structure, waste tires have strong heat resistance and biodegradation resistance, making them difficult to degrade naturally. Recycling high-value chemical products from waste tires by pyrolysis is a promising and attractive method. The pyrolysis behaviour of rubber particles was thoroughly examined based on a delicately designed furnace and the pyrolysis product was analysed through Py-GC-MS. Innovative stage pyrolysis system was developed based on a hollow-auger reactor with a capacity of 1 ton per day. The quality of pyrolysis products was effectively improved through the idea of "Step pyrolysis-Two-stage condensation-Independent energy supply". The light transmittance of the toluene extract of the obtained pyrolysis carbon black reached 99%, and the flash point of the pyrolysis oil reached 76.5 °C. After milling, the raw carbon black could replace the N660 commercial carbon black in tire manufacture. According to the above researches, two engineering demonstrations by integrating pyrolysis, combustion, and waste heat utilization have been carried out based on existing coal-fired units and carbon black production plants, and annual processing capacity of each production line has exceeded 5,000 tons.
  1. A novel step - continuous pyrolysis device was developed.
  2. The carbon black yield ranged from 38.0% to 41.7%, with the light transmittance of extracted toluene reaching 99%.
  3. Two engineering demonstrations have been carried out based on an existing coal-fired unit and a carbon black production plant.
