Abstract

This study is concerned with the influence of additives on the steam gasification of polyvinyl chloride (PVC) waste. Three types of PVC waste, namely pipe waste, cable waste, and flooring, were tested. The presence of additives proved to have a profound effect on the carbon-to-gas conversion. Plasticizers and other organic additives caused an increase in carbon-to-gas conversion. Inorganic additives, especially calcium, caused a decrease in carbon-to-gas conversion, resulting in an overall decrease in the yield of syngas for all three types of waste. This decrease is probably caused by the deposition of Ca on the surface of the alumina bed material. In addition, calcium reacts with the HCl formed to give CaCl2. This results in a decrease in the recovery of hydrochloric acid.
