Sintesis Dan Karakterisasi Katalis Cao-Sio2 Dari Cangkang Kerang Darah Dan Ab…

Calcium oxide (CaO) is a catalyst that is widely used for biodiesel synthesis reactions, but the CaO catalyst has the weakness of a low surface area. Therefore, to increase biodiesel yield the CaO catalyst needs to be modified using silica to increase the catalyst surface area and catalytic activity. The aim of this research is to synthesize and characterize the CaO catalyst modified by SiO2 ar…
