Biodiesel fuel production with solid amorphous-zirconia catalysis in fixed bed reactor.
TLDR
Amorphous zirconia catalysts, titanium-, aluminum-, and potassium-doped Zirconias, were used in the transesterification of soybean oil with methanol at 250°C, and the esterification of n-octanoic acid with methenol at 175-200°C.Abstract:
Amorphous zirconia catalysts, titanium-, aluminum-, and potassium-doped zirconias, were prepared and evaluated in the transesterification of soybean oil with methanol at 250 °C, and the esterification of n-octanoic acid with methanol at 175–200 °C. Titanium- and aluminum-doped zirconias are promising solid catalysts for the production of biodiesel fuels from soybean oil because of their high performance, with over 95% conversion in both of the esterifications.read more
