UTILIZATION OF PLASTIC WASTE INTO LIQUID FUELS

Abstract

The production of plastic waste in Indonesia in increasing from year to year. Along with that, then the unused plastic waste in the environment increases. Thgis problem is greated because of the plasic waste can not decompose easily, if only just left. Therefore, efforts are needed to convert plastic waste into liquid fuel that is by catalytic pyrolisis. The volume of piroligneuos liquid (obtained) was  mearsuredand it’s physical properties were analyzed. The analys include distillation ASTM, spgr, and ⁰API. From the data obtained showed that pyrolysis catalysts are able to increase the pyrolysis process by lowering the temperature and time of decomposition, so the maximum liquid fuel was obtained at 0,024 weight fraction of catalyst, and in the temperature range below 350⁰C obtained result could reach more than 50%. The optimum temperature of pyrolyzing plastic waste into liquid fuel was 329⁰C, and the weight fraction of bentonite catalyst was 0,024. from the analysis of ASTM (D-86) there were there component of pyroligneus liquid, there are gasoline, kerosene, and diesel. From the result of analizing showed the pyroligneous liquid had spgr was 0,7702 near with spgr of gasoline with octane number 91 among 0,715-0,780. ⁰API result was 52,2185 or near with ⁰API of gasoline.
