    Abstract: 本研究以變壓吸附程序處理發電廠所排放之煙道氣以及經由水煤轉化反應器生成合成氣中的二氧化碳,目的在於將二氧化碳回收並濃縮,使之封存以減少人為造成的溫室氣體排放。
    ;This research studies concentrating carbon oxide from the flue gas of an power plant and from syngas after water gas shift reaction by pressure swing adsorption (PSA) process, so that the concentrated carbon oxide can be captured and storaged to reduce greenhouse gas emission.
    Commercialized Zeolite 13X is used in this study. In the beginning of this study, the experimental adsorption isotherm data were regressed to obtain the parameters of Langmuir-Freundlich isotherm equation. Then the k value of linear driving force (LDF) model were calculated by theory and verified by breakthrough curve and desorption experiment. Then we verified the simulation program by comparison with the data of a single-bed four-step process experiment. The agreement is quite good.
    At the end of this study, both two-bed six-step PSA process for syngas (41.4% CO2,1.3%CO,57.3%H2) and three-bed twelve step PSA process for flue gas (15%CO2,85%N2) were studied to find the optimal operating conditions. The optimal operating conditions can be obtained by assessing different operating variables such as bed length, feed pressure, vacuum pressure, and the time of each step.
