摘要

本研究主要著重在比較印尼煤的吸附行為。在樣品經過水分去除的步驟後，觀察當壓力逐漸增加的情況下，各樣品的二氧化碳及甲烷吸附量的趨勢和吸附量最大值的比較。隨後將最大吸附量與各種煤特性作圖，探討在不同煤樣的先天條件下，煤樣吸附能力是否有顯著趨勢。
目前世界各國在二氧化碳的排放及管理上已有一定規範，即便如此，每年仍會有大量二氧化碳無法被代謝，因此降低現有的二氧化碳濃度為主要考量。現階段將二氧化碳封存在煤層的技術是較為經濟且成熟的。
在過去的文獻中，水分、微孔特性、鏡煤素反射率(RO%)對於吸附量趨勢已具有確定的相關性。在本次實驗中，除了比較過去文獻是否有一致性外，也會利用其他的煤特性，評估各地方煤樣的吸附能力。

This research is mainly focus on comparing the adsorption conduct of Indonesia coal. The properties after removing the water, while the pressure is getting higher, to observe the comparison of the max. adsorption capacity trendy of each CO2 and CH4 properties. And then to make diagram of the max. adsorption capacity and each specification of coal. Under the natural conditions of various coal specimen, to analysis whether if the coal’s adsorption has obvious trendy.
Nowadays, all the world has a due standard for CO2 emission and management, even though, yet the mass CO2 can not be metabolic every year. Therefore, to reduce the current CO2 consistency will be the main consideration. At this stage, to preserve the CO2 in coal layer technology is more economic and mature.
From the past documentary, water, micro hole feature, RO%, for which the adsorption already has specify relationship. From his experiment, except to compare the conformity with the past documentary, but also will adapt the other coal’s characteristic to evaluate the adsorption capacity of coal property from each place.
