Resumen
Catalytic dry reforming of mixed waste plastics, from a range of different municipal, commercial and industrial sources, were processed in a two-stage fixed bed reactor. Pyrolysis of the plastics took place in the first stage and dry (CO2) reforming of the evolved pyrolysis gases took place in the second stage in the presence of Ni/Al2O3 and Ni-Co/Al2O3 catalysts in order to improve the production of syngas from the dry reforming process. The results showed that the highest amount of syngas yield was obtained from the dry reforming of plastic waste from the agricultural industry with the Ni/Al2O3 catalyst, producing 153.67 mmolsyngas g−1waste. The addition of cobalt metal as a promoter to the Ni/Al2O3 catalyst did not have a major influence on syngas yield. Overall, the catalytic-dry reforming of waste plastics from various waste treatment plants showed great potential towards the production of synthesis gases.
