PYROLISIS OF KAPOK SEED OIL (CEIBA PENTANDRA) INTO LIQUID FUEL WITH VARIATIONS OF TEMPERATURE AND REACTION TIME
Fossil fuel is a traditional energy source that is still widely used in various sectors. The industrial and transportation sectors are the main sectors that play an important role in the use of this energy source. Along with the increasing demand for fuel, the problem of fuel scarcity arises, because so far its needs are highly dependent on fossil fuels which are non-renewable materials. For this reason, it is necessary to develop other energy sources as renewable alternatives in order to reduce dependence on fuel oil. One of the renewable energies that can be developed is liquid fuel produced from kapok seed oil. This study aims to obtain the optimum reaction temperature and time that produces the highest % yield. Liquid fuel is made from kapok seed oil (ceiba pentandra) each as much as 500 grams and 10% zeolite catalyst through a pyrolysis process at temperatures of 310°C, 330°C, 350°C, 370°C and 390°C with reaction times of 100 minutes, 120 minutes and 140 minutes in catalytic cracking reactor. To determine the quality of liquid fuel, testing for density, viscosity, flash point, cetane number, and GC-MS analysis was carried out. Based on the highest % yield of 13.4664% at a temperature of 370°C and a time of 140 minutes, the resulting liquid fuel production has a density value of 835.70 kg/m3, a viscosity value of 2.70 mm2/s and a cetane number of 79.8. The results of the GC-MS analysis showed that in liquid fuel pyrolysis of kapok seed oil, there was a gasoline fraction (C5 – C12) of 23.07%, a kerosine fraction (C13–C14) of 6.02%, and a diesel fraction (C15 – C19). by 51.2%.
