Abstract
PP (Polypropylene) plastic waste pyrolysis oil can be used as fuel oil through the pyrolysis process, but there is a need for efforts to improve the quality of the oil, one of which is with oxygenate additives, namely Dimethyl Carbonate (DMC). DMC has a high oxygen content of 53%/weight and is a green chemistry additive. The focus of this research is to determine the optimum concentration of DMC which can improve the quality of PP waste pyrolysis oil. The method used is pyrolysis of PP waste at a temperature of 80-90oC and then purification by distillation, then blended with DMC 5% v / v (PPD5), 10% v / v (PPD10), and 13% v / v (PPD13) by tracing several parameters such as viscosity 40oC, density 15oC, calorific value, and octane value. The results obtained from PP100 pyrolysis oil (after purification) contain more carbon range C5-C 12 70.64% which is a component of the gasoline hydrocarbon range. The optimum concentration to improve the quality of PP waste pyrolysis oil is found in PPD13 samples which is based on its ability to increase the octane value of RON from 89.3 (PP100) to 90.8 and a larger anti-knocking index compared to other DMC concentrations, which is 89.9
