Catalytic Performance of CaO/SiO2 Prepared from Local Limestone Industry and Rice Husk Silica

This research was conducted to study the performance of CaO/SiO2 prepared from local limestone and rice husk silica as catalyst for transesterification of coconut oil. A series of catalysts with CaO loads of 5, 10, 15, 20, and 25% relative to silica was prepared using sol-gel method, followed by cal...
