Solar pyrolysis of scrap tire: optimization of operating parameters
- 76 Downloads
Pyrolysis of scrap tire using concentrated solar radiation is a novel way to upgrade feedstock. In this investigation, best operating condition for maximizing pyro-oil yield was determined. The parameters varied were the temperature of the reactor, flow rate of nitrogen gas and size of the feed particles. The maximum pyro-oil yield was 52 wt% at 400 °C of reactor temperature and nitrogen flow rate of 6 lpm for a feed size of 4 cm3. The pyro-oil and char were characterized according to ASTM standards. This research showed the feasibility of converting scrap tire into pyro-oil by using solar energy via pyrolysis and analysis showed the potential of pyro-oil and char as a valuable source of chemicals.
