Transesterificação etílica de óleos de soja e de fritura empregando catalisadores alternativos baseados em argila clarificante pilarizada ou cinzas de casca de arroz modificadas com pentóxido de vanádio

Resumo

Frying oil conversion to biodiesel was monitored employing the FTIR technique (using an analytical curve). 10 mass % V₂O₅/CCA-ttq catalysts show very efficient to ethylic biodiesel synthesis, with 99.9% frying oil conversions to biodiesel in 6h, at 200 ^oC. Low conversions were observed in minor condition of temperature and times.
