Possible acceptable recycling processes of vegetable oils are cracking and pyrolysis. Pyrolysis is a common practice and an effective method for recycling waste disposal. The sunflower oil can be pyrolyzed into hydrocarbon-rich products. Alkali (Na2CO3) was used in the pyrolysis experiments. Interest is focused on gasoline-rich engine fuel production. The liquid products are usually composed of higher boiling point hydrocarbons. In order to obtain useful gasoline-range hydrocarbons from the pyrolysis oil, fractional distillation is preferred for product separation. The highest yields of gasoline were 55.2% for the gasoline from sunflower oil, which can be obtained from the pyrolysis with 5% catalytic runs. The results show that the product compositions are affected by catalyst content and temperature.
