Automobile Shredder Residue (ASR) destruction in a plasma gasification reactor
Test results on Automobile Shredder Residue (ASR), or car fluff, demonstrated destruction efficiency and safe conversion to synthesis gas and a glass residue, in a plasma gasification system. The synthesis gas consists primarily of hydrogen and carbon monoxide in the range between 20 and 22 vol-% respectively, or 45 and 55 vol-% dry basis, when corrected for nitrogen. In dry reforming operation, carbon dioxide conversion approached 90%. The system is designed to work with oxygen in autothermal conditions, reducing thus the electric power requirement for the plasma reactor. The vitrified residue leach rate makes the product suitable for construction works.
