The increasing generation of plastic waste poses a significant threat to humanity and ecosystems. To mitigate the dangers associated with large amounts of plastic waste, it is essential to develop technologies for its utilization. Pyrolysis has emerged as an effective technology for managing plastic waste because it not only treats the waste but also cost-effectively produces valuable resources such as oil and gas. Pyrolysis oil is separated into heavy oil and light oil through distillation, based on their differing flash points. Using light oil, which has a low flash point, as a fuel can lead to undesirable and dangerous situations, such as explosions. However, light oil can be used to produce hydrogen through steam reforming reaction. Hydrogen is a key component of achieving a net-zero society because it emits only water when used as fuel in burners or fuel cells. In this study, mesoporous SiO2-supported catalysts with different active metals (Ni, Co, and Fe) were applied to the steam reforming reaction of light oil derived from plastic waste. The mesoporous SiO2 support was synthesized via a hydrothermal method, and the catalysts were prepared using an impregnation method. The results showed that the prepared catalysts achieved similar light oil conversion rates, with the Ni/SiO2 catalyst demonstrating the highest H2 yield. This superior hydrogen yield can be attributed to the properties of Ni, which effectively breaks hydrocarbon H-C bonds, and the easier reducibility of the Ni/SiO2 catalyst. Therefore, this study confirmed that Ni is as a promising candidate for reforming reaction of light oil derived from plastic waste to produce hydrogen.
