Chromium-tungsten heterogeneous catalyst for esterification of palm fatty acid distillate to fatty acid methyl ester
Chromium-tungsten mixed oxides heterogeneous catalysts were prepared and evaluated in the esterification of palm fatty acid distillate (PFAD) to produce fatty acid methyl ester (FAME). The reactions were conducted in a batch reactor at temperature range of 110-190 °C and catalysts were characterized...
