Utilization of Cuttlefish Bone as The Alternative Source of Heterogenic Alkali Catalyst

Abstract

This research aims to determine characteristic of heterogeneous alkali catalyst which produced from cuttlefish bone. The catalyst was made by calcination process at 800 °C for 4 hours. The characterization was done by XRD (X-ray diffractometer) and SEM-EDS (Scanning Electron Microscopy-Energy Dispersive X-ray). XRD result showed heterogeneous alkali catalyst from cuttlefish bone have high crystallinity with lime mineral phase. In comparison with calcium oxide powder, the cuttlefish bone catalyst has the highest crystallites (6000) than calcium oxide powder (4000). SEM-EDS result showed the microstructure of cuttlefish bone heterogeneous base catalyst morphologically have dissimilar particle shape and size comparing to tohor lime heterogeneous base catalyst. Cuttlefish bone catalyst particle size is smaller than catalyst from tohor lime. Morphologically showed the difference is cuttlefish bone catalyst has tidy-clots form while tohor lime catalyst has slab-shaped. These particle shape and size will affect to catalyst properties, which smaller particle size will be affected to effectivity of catalyst activity. From EDS result showed main mineral compound of cuttlefish bone catalyst is calcium attain 93%.
