Bentonite has been historically employed as a filling material for oil refining filters due to its easy availability and its cheap price. In the present communication our early results from the filtration of degummed WCO through a pad of bentonite are presented. In particular, the variation of density, flash point and color have been monitored prior and after the filtration process and compared with samples of non-filtered WCO. An early classification of the bentonite employed has been conducted on the basis of FT-IR and XRD measurements. eng info:eu-repo/semantics/openAccess Waste cooking oil Bentonite Flash point FT-IR XRD Bentonite as a refining agent in waste cooking oils recycling: flash point, density and color evaluation info:eu-repo/semantics/article
