Thermodynamic equilibrium calculation suggests that it is possible to perform the low-temperature steam reforming of polystyrene. In this study, we synthesized a Ni-Fe bimetallic catalyst for the low-temperature (500 �C) steam reforming of polystyrene. XRD characterization showed that Ni-Fe alloy was formed in the catalyst. Compared to conventional Ni catalysts, the Ni-Fe bimetallic catalysts can significantly increase the H2/CO ratio in the produced gas with high gas production yield. The online gas analysis revealed that H2, CO, and CO2 were formed in the same temperature range. H2 and CO were formed simultaneously through steam reforming reactions, and CO2 was formed through water-gas shift reaction. New morphologies of carbon deposition on the catalyst surface were found, suggesting that wax could be condensed on the catalyst surface at a low temperature. � 2020 Final 2023-05-29T08:10:55Z 2023-05-29T08:10:55Z 2020 Article 10.1016/j.wasman.2020.01.017 2-s2.0-85077951887 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85077951887&doi=10.1016%2fj.wasman.2020.01.017&partnerID=40&md5=9996b1c8a83acd28ca60924717569f27 https://irepository.uniten.edu.my/handle/123456789/25561 104 42 50 Elsevier Ltd Scopus |
