This study aimed to determine the ratio of catalyst and styrofoam mixture, which produced the optimum pH, the weight ratio of catalyst and pyrolysis temperature, which produced the volume of kerosene, the ratio of catalyst, and styrofoam mixture, which produced the highest kerosene. This research method consisted of; first, preparing tools and styrofoam materials as much as 250 grams and has been cut by ± 2 cm. Then, the material was put into the pyrolysis reactor and run according to the time variables of 30 minutes and 60 minutes, and the temperature variables were 250°C, 350°C, and 450°C. The research results in pyrolysis liquid from styrofoam waste had a heating value of 42.238 J/gr. The best flame test was at a variable of 60 minutes at 450 °C. The fire was orange and produced smoke. If the temperature of the pyrolysis process was higher, the fire would ignite faster so that the phenomenon would occur. The highest volume of pyrolysis liquid was 60 minutes at 450°C at 83 ml. The lowest volume was 30 minutes at 250°C, the highest density was 60 minutes at 450° C at 0.87966667 J/gr, and the lowest density was 30 minutes at 250°C at 0.83933333 J/gr, the highest calorific value pyrolysis liquid was 60 minutes at 450°C at 42.238 J/gr, and the lowest calorific value was 30 minutes at 250°C at 35.348 J/gr. The gas chromatography test with the highest composition was found in benzene at 26.36%, and the lowest composition was in eicosane at 4.31%. [ABSTRACT FROM AUTHOR] |
