| 摘 要： | 利用电场作用通过交流和直流等离子体在低温、常压和低功率下催化反应将甲烷直接转化为碳二烃（乙烷、乙烯、乙炔）。考察了在对称电场作用下催化剂的催化性能。实验结果表明，在交流电场作用下，碳二烃选择性差别不大；甲烷转化率的大小顺序为： ＭｎＯ_２／Ａｌ２Ｏ３＞Ｎｉ／Ａｌ２Ｏ３＞ＭｏＯ_３／Ａｌ２Ｏ３＞Ａｌ２Ｏ３＞Ｎｉ／Ａｌ２Ｏ３＞ＭｏＯ_３／Ａｌ２Ｏ３＞Ｎｉ／ＮａＹ＞Ｐｄ／ＺＳＭ－５＞Ｎｉ／Ｈ４Ｍｇ２Ｓｉ３Ｏ４＞Ｎｉ／ＺＳＭ－５＞Ｃｏ／ＺＳＭ－５＞无催化剂：在直流电场作用下，碳二烃选择性差别也不大（除Ｎｉ／ＮａＹ外），甲烷转化率的大小顺序为： Ｎｉ／Ａ１２Ｏ３＞Ｎｉ／Ｈ４Ｍｇ２Ｓｉ３Ｏ４＞Ｎｉ／ＺＳＭ－５＞Ｃｏ／ＺＳＭ－５＞ＭｎＯ２／Ａ１２Ｏ３＞ＭｏＯ３／Ａ１２Ｏ３＞Ｎｉ／ＮａＹ＞无催化剂＞Ｐｄ／ＺＳＭ－５。

| Abstract: | Low-power catalytic conversion of methane to C_2 hydrocarbons (ethane, ethylene and acetylene) through AC or DC plasma catalysis reactions in symmetric electrical field was studied under low temperature and atmospheric pressure. The function of catalyst was tested. The appropriate condition was: voltage 90 V~110 V (power 15 W~20 W DC), voltage 20 V~40 V (AC). The appropriate inlet flow of methane was 45 mL/min~80 mL/min under AC and DC field. The selectivity to C_2 hydrocarbons was above 95%. |
