Rancangan Pabrik Triasetin Dari Esterifikasi Gliserol Dan Asam Asetat Dengan …
Biodiesel is an alternative energy that can replace diesel fuel. The process of making biodiesel in the triglyceride transesterification reaction produces a byproduct called glycerol, which is approximately 10% of the amount of biodiesel produced. Currently, glycerol has not been processed much so it still has a low selling value. Therefore, glycerol processing is necessary in order to convert …

CaO catalyst impregnated with SiO2 (silica) is a heterogeneous catalyst that is widely used in transesterification reactions for biodiesel synthesis. However, the yield of biodiesel produced is not optimal, due to the small surface area and stability of the catalyst, requiring modification with other types of metal oxides such as Fe₂O₃. Fe₂O₃ has high porosity and stability thus can inc…
