Challenges associated with choosing operational conditions for triglyceride thermal cracking aiming to improve biofuel quality

- Thermal cracking of waste cooking oil was used to produce renewable fuels.
- Product distribution was influenced by temperature and residence time.
- Higher temperature and residence time increased the benzene content.
- Paraffins, isoparaffins and naphthenes remained constant under all conditions.
- Olefin hydrocarbons varied considerably with residence time.
