Hydrogen Production by Steam Reforming of Pyrolysis Oil from Waste Plastic over 3 wt.% Ni/Ce-Zr-Mg/Al2O3 Catalyst

Sustained increase in plastic use has placed a significant burden on waste disposal infrastructure. Pyrolysis is the process of decomposing high-molecular-weight compounds by heating plastics at 500–1000 °C without oxygen. This considerably reduces greenhouse gas emissions and high alternative energy effect (0.57 TOE ton−1). After separation process, oil produced pyrolysis (C5–C20) can yield naphtha (C6–C7). Subsequently, hydrogen be through reforming reaction this oil. Here, we from over Ni/Ce-Zr-Mg/Al2O3 catalyst using steam process. A model combining major substances C6 C7 (hexane, hexene, heptane, heptene, toluene) was formed. From products, obtained based analysis H2, CO, CO2 concentrations chromatography. The N2 O2 addition analyzed within temperature range 750–850 °C, steam/carbon (S/C) ratio 0.6–4, space velocity 7600–19,100 h−1. In addition, durability test performed 3 wt.% catalysts for 100 h; 91.3% maintained refined
