中文摘要 | 以頻率 13.56MHz RF 水汽電漿,進行二氧化碳氣體分解;由文獻中得知一氧化碳及氫為甲醇製備之前驅物,故實驗中運用多頻光譜儀觀察電漿內之CO 及H 訊號強度,推測實驗條件下甲醇產生可能性;本實驗之參數:(1)CO2 濃度:40、60、80 (%) (2)放電功率:200 、300 、400 (w) (3)壓力:500 、600 、800 、1000 (mtorr)。由CO H CH OH 2 3 + 2 ↔ 之反應式可得知,CO 及H2之比例為1:2可產生甲醇;故利用光譜儀所偵測之CO 及H 訊號強度比較及推測下,實驗條件:CO2 濃度40 %、500 mtorr、400 w,如可產生甲醇,其產量可能為最高。 |
英文摘要 | This paper is to describe the study of decomposition of CO2 gas by using 13.56 MHz RF H2O plasma. The intensity of Carbon-mono-oxide and Hydrogen signal in plasma were measured by using a multi-channel spectrometer, and the optimum parameters to transform CO2 into methanol were discussed. The parameters studied in this experiment were as follows : (1) CO2 concentrations : 40%, 60% and 80%. (2) RF Power levels : 200w, 300w and 400w. (3) The chamber’s pressures : 500mtorr, 600mtorr, 800mtorr and 1000mtorr. If the conversion was described as following equation : CO H CH OH 2 3 + 2 ↔ , one can use the intensity of CO and H to estimate the possible production of methanol. The results showed that the biggest possible production will be under the following parameters : CO2 concentration 40%, pressure 500mtorr and power level 400w. |
