NOVEL DEVELOPMENTS OF WHITE CLAY FILLER CATALYSIS FOR BIODIESEL PRODUCTION
Keywords:biodiesel, calcium oxide catalyst, White clay
This study was conducted to examine the performance of white clay as catalyst filler for biodiesel production. White clay catalyst prepared with a calcination temperature of 900 °C for 5.5 hr exhibited 12.57 wt% calcium oxide converted from calcium carbonate and providing strong base of 2.30 mmol/g. Furthermore, calcium oxide was confirmed through characteristic of XRD patterns at 32.32o, 37.47o, 53.00o, 62.72o, 64.92o with a high porosity. 1H nuclear magnetic resonance (1H NMR) showed that palm oil could be readily converted to a biodiesel product through transesterification by using 9 wt.% (by weight of palm oil) calcium oxide catalyst: methanol (1:9) at 65 °C for 2 hr. The maximum biodiesel production more than 80 % was obtained and reusable up to 4 times of consecutive runs under the optimum conditions compared with the commercial available. These findings have opened novel catalyst filler for highly biodiesel production with economical and environment-friendly materials.
