PYROLYTIC COPROCESSING OF USED VEGETABLE OIL, WASTE LUBRICATING OIL AND PLASTICS TO LIQUID FUELS ON THE TURBULAR REACTOR

摘要

The thermal cracking of waste lubricating oil, used vegetable oil and used polypropylene can be produce liquid fuels such as gasoline, kerosene and other hydrocarbon distribution. This research aims to studies the thermal cracking of waste lubricating oil, used vegetable oil and used polypropylene to liquid fuels in the continuous tubular reactor diameter of 0.925 centimetre, length of 12 metre under the condition of temperature range of 400 - 600°C, feeding rate of a substance starts 1.23 - 9.45 gram per minutes. The appropriate condition gave the highest conversion to liquid about of 95.8% yield therefore the studies claimed that the feedstock will be cracked and formed to light hydrocarbon molecules. The liquid products were analysed by distillation gas chromatograph that major product is gasoline and diesel, with slight production of C4-gas and small amounts of solids were present.
