One of the advantages of plastic gasification is its ability to accommodate a variety of feedstock selections and plastic mixes. Significant energy savings in recycling plastics would be possible not only compared to the mechanical recycling but also to the traditional gasification because plastics carry higher heating values than traditional carbon feedstocks. The sustainability of such a process, however, requires overcoming certain operational challenges with refractory liner performance with respect to novel slag chemistry and properties as introduced by plastic ashes. The plastic ashes tend to be rich in alkaline earth metals such as Ca and Mg. In this work, synthetic plastic slag was interacted with select refractory bricks designed and manufactured by HWI in simulated gasification environments at 1500 °C. The paper will discuss refractory behavior against plastic slag including slag penetration, interfaces, and refractory degradation mechanism.
