The study of the morphology of the catalyst, calcium oxide was pervade soaked with chemicals such as potassium fluoride (Potassium Fluoride: KF) Potassium Chloride (Potassium Chloride: KCl), potassium bromide (Potassium. Bromide: KBr), potassium iodide (potassium iodide: KI) and barium chloride (barium chloride: BaCl2) compared to calcium oxide derived from the shells plugging techniques to analyze the physical structure with the electron beam SEM (. Scanning Electron Microscopy: SEM) when considering Figure 4.1 (a), (B) and (C) is inserted before firing shells. Found that the surface is quite rough. Non-porous yet After that, when the shell plug to burn under 900 ° C for 2 hours, the morphology of the shell mussel firing Figure 4.1 (D), (E) and (F) has a surface somewhat. smooth and porous lot. The appearance of pores formed due to the dissolution of calcium carbonate into calcium oxide and carbon dioxide. As a result, the surface of the catalyst is characterized by spongy happen
considering Figure 4.1 (G), (H) and (I), a calcium oxide Erb was drenched with potassium fluoride. Found a small lump, and a relatively smooth surface. This causes the spongy
considering Figure 4.1 (J), (K) and (L), a calcium oxide is impregnated with potassium chloride pervade. That looks like a large square bales are covered with many small particles. The large square bales can be caused by the grinding is not fine. They found a small amount of large pore
considering Figure 4.1 (M), (N) and (O), a calcium oxide is impregnated pervade potassium bromide. That is similar to calcium oxide is impregnated with potassium chloride pervade. However, small particles are covered with tightly packed less. This will cause a large pore
considering Figure 4.1 (P), (Q) and (R), a calcium oxide is impregnated with potassium iodide pervade. That is similar to calcium oxide is impregnated with potassium chloride pervade. However, small particles are compressed together until a large number of particles. This will cause a large pore little
considering Figure 4.1 (S), (T) and (U), which is a calcium oxide is impregnated with barium chloride pervade. Found that the surface looks rough. This is due to a combination of pre-small particles to stick together a lot.
