Sintesis Dan Karakterisasi Katalis Cao-Sio2 Cangkang Kerang Darah Dan Abu Sab…

The CaO catalyst derived from blood cockle shells used for biodiesel synthesis has the weakness of a small surface area, so it needs to be modified with a porous material to increase its catalytic activity. One of the porous materials used is SiO2, which comes from areca palm ash. The aim of this research is to synthesize a CaO catalyst modified by SiO2 from areca palm ash using the wet impregn…
