Production of Bio‐Oil from Waste Cooking Oil by Pyrolysis

Abstract Waste cooking oil (WCO) is an important feedstock for biofuel production due to its low cost and extensive availability, primarily by transesterification. A more recent approach to take advantage of this feedstock is through pyrolysis. In this study, WCO was collected from a fast food restaurant and then pyrolyzed, employing two different heating rates and four temperatures, at a fixed residence time. The composition of the products was determined by gas chromatography‐mass spectrometry. The best bio‐oil yield was 77.59 %, obtained at 700 °C and 10 °C min −1 . The highest contents of octane, nonane, and decane were reached at 400 °C and 15 °C min −1 . Therefore, WCO proves to be an important resource for obtaining biofuel or chemical solvents for the industry.
