“…Clays exhibit a complex and versatile distribution of surface ions, with a high cation exchange capacity, which gives them some catalytic activity for several chemical reactions (Busca, 2007;Lee, 2014). However, the results suggest that there is no catalytic activity in the methyl transesterification reaction applying natural montmorillonite clay or clay heated to 400 or 700°C, as also observed in other studies (Farias et al, 2015;Alves et al, 2014).…”

“…For this research, a bentonite from Brazilian Bentonite Company Ltda (CBB) was used. Bentonite is mainly composed of clay minerals of montmorillonite and kaolinite, containing 62.5% of SiO 2 , 20.5 % of Al 2 O 3 , 10.2 % of Fe 2 O 3 , 4.8 % of e MgO and 2.0 % are other elements (da Costa & de Andrade Lima, 2021).…”
