| Summary: | 碩士 === 國立屏東科技大學 === 工業管理系所 === 104 === Comparatively, this study experiments the characteristics of carbonization and activation in terms of yield rates, iodine, the specific surface area, and pores, between the materials of coconut shells and beeches from Germany through the designed high pyrolysis carbonization equipment. This study adopts physical activation method and utilizes steam as activation agents to differentiate the characters of activated products between beeches and coconut shells. The experimental results indicate that the range of yield rates is 13-30% and the activated carbon produce features alkaline with the iodine values of 490-1122mg/g, specific surface areas of 240-1234 m2/g, and average of pores 2nm. To compare the characteristics of activated carbons between the produce in this experiment and the product in markets, this study experiments the effects on water purification, adsorption, and the decrease function of ammonia nitrogen for aquacultures under various conditions of quiescence, potency, and time lasting. The experimental results indicate that the higher the adsorption capability, the more the effect of decrease of ammonia nitrogen. However, the activated carbon by the method of steam for beech is superior to coconut shells either in the decrease of ammonia nitrogen or in pore purification.
