Polypropylene Pyrolysis (PP) Uses Ni and NiMo Catalysts Supported on Mesoporous Silica

Abstract

Research has been conducted to find out the amount of liquid fractions resulting from polypropylene plastic pyrolysis (PP) and the selectivity of Mesoporous Silica (MS), Ni/SM, and NiMo/SM against the fraction of gasoline and diesel pyrolysis results of polypropylene plastic (PP). The method in this study is pyrolysis method (heating in the absence of oxygen) and analysis of liquid fraction of pyrolysis result using GCMS (Gas Chromatrography Mass Spectrometry). In this study, the largest number of liquid fractions produced on pyrolysis with Ni-MS catalyst was 71.68 wt.%. GCMS analysis showed all selective catalysts for gasoline for mesoporous silica (MS), Ni/MS, and NiMo/MS by 73.75%, 57.21%, and 80.08%.
