Sintesis Katalis Cao-Sio2 dari Cangkang Kerang Darah dan Sabut Kelapa Untuk …

CaO catalyst from blood cockle shells calcined for 5 hours at 900oC is a heterogeneous catalyst commonly used for biodiesel synthesis. However, the surface area of the CaO catalyst is still too low so it needs to be modified with porous materials such as silica (SiO2) from coconut fiber to increase its catalytic activity. The aim of this research is to synthesize a CaO catalyst from blood cockl…
