    Abstract: 本研究以變壓吸附程序處理甲醇裂解後所產生之模擬氣體(一氧化碳33%、氫氣66%及甲烷1%),目的在於將一氧化碳以及氫氣回收並濃縮,使之儲存並利用,氫氣可作為能源之利用,一氧化碳可作為合成化學之原料。
    ;This research studies the separation and concentration of carbon monoxide and hydrogen from the methanol decomposition product gas by pressure swing adsorption (PSA) process, so that the high concentration carbon monoxide and hydrogen can be producted .Hydrogen can be used as energy source and carbon monoxide can be used for raw chemical subtances.
    Pressure swing adsorption is a cyclic process to separate gas mixtures based on the difference of adsorption capacity of each component on adsorbent. This technology consists of gas adsorption at high pressure and desorption at low pressure to produce high-purity product.
    Zeolite PU1 adsorbent is used in this study. First, the experimental adsorption isotherm data from literatures were regressed to obtain the parameters of extend Langmuir isotherm equation. Then we verified the simulation program and adsorption parameters by comparison with the plant data of concentrating carbon monoxide and the experimental data of concentrating hydrogen from literatures. The agreement is quite good.
    Finally, a four-bed twenty-four-step PSA process with methanol decomposition product gas (33% CO , 66 %H2, 1%CH4) as feed was studied to find the optimal operating conditions. The optimal operating conditions can be obtained by assessing different operating variables such as bed length, feed flow rate, feed pressure, vacuum pressure, storage tank volume, and the time of each step.
