Catalytic Gasification of Plastics Using Ni Loaded Catalysts

The activity of Ni/Si with the molar ratio of 0.5 and 1 and Ni/silica were tested on biomass gasification. The catalyst with the higher nickel content (molar ratio 0.5) for Ni/silicate and Ni/silica resulted in higher gas yield and more H₂ and CO generation while Ni/Si (0.5) generated less CO₂ compared to Ni/silica. The higher nickel content was used for the experiments to test silicate and silica as a support. The catalysts were characterized using BET and XRD analysis. Both the supports (silica and silicate) showed promising stability at higher temperature and can be employed in gasification
