Pyrolysis oil (C5-C20) produced using plastic non-oxidative pyrolysis technology produces naphtha oil (C5-C10) through a separation process, and naphtha oil produces hydrogen through a reforming reaction to secure economic efficiency and social and environmental benefits. In this study, waste plastic pyrolysis oil was subjected to a steam reforming reaction on a commercialized catalyst of 46-3Q And it was found that the 46-3Q catalyst reformed the pyrolysis oil to produce hydrogen. Therefore, an experiment was performed to increase hydrogen yield and minimize the byproduct of ethylene. The reaction experiment was performed using actual waste plastic oil (C8-C11) with temperature, steam/carbon ratio (S/C) ratio, and space velocity as variables. We studied reaction conditions that can maximize hydrogen yield and minimize ethylene byproducts.
