Fluidized bed steam cracking of rapeseed oil: exploring the direct production of the molecular building blocks for the plastics industry

Abstract Fossil-based production of plastics represents a serious sustainability challenge. The use renewable and biogenic resources as feedstocks in the plastic industry is imminent. Thermochemical conversion enables molecular building blocks materials from widely available resources. Waste cooking oil (WCO) significant fraction these This work provides insights into thermochemical fatty acids present WCO, where rapeseed used source acids. experimental results reveal that fluidized bed steam cracking temperature range 650–750 °C yields product distribution rich light olefins mono aromatics. Up to 51% olefins, 15% aromatics, 13% paraffins were recovered through cracking. means up 70% carbon was converted single step. main conclusion this study WCO vegetable oils represent viable for direct blocks, achieved beds.
