混合导体膜反应器用于甲烷部分氧化制合成气的研究
Mixed conductor membrane reactor for partial oxidation of methane to syngas
为解决甲烷部分氧化反应制合成气中的过度氧化问题,通过引入混合导体透氧膜反应器与甲烷部分氧化反应的耦合,提高合成气的选择性。以Ni/γ-Al2O3和Ni/SBA-15为催化剂对膜反应器性能进行测试。结果表明,Ni/SBA-15催化剂的介孔结构在测试后坍塌,性能下降。而在950℃下,以Ni/γ-Al2O3为催化剂的膜反应器甲烷转化率达92%,CO选择性高达99%。经500 min稳定性测试,膜反应器展现出良好的甲烷转化率和化学稳定性。
To address the over-oxidation issue in syngas production from methane partial oxidation reaction,the syngas selectivity is improved through coupling a mixed conductor oxygen permeable membrane reactor with methane partial oxidation reaction.The performance of membrane reactor is tested by using Ni/γ-Al2O3 and Ni/SBA-15 as catalysts.Results show that after the test,the mesoporous structure of Ni/SBA-15 catalyst collapsed and its performance decreased.In comparison,the conversion of methane over the membrane reactor with Ni/γ-Al2O3 as catalyst reaches 92% at 950℃,and the CO selectivity is as high as 99%.After 500 min of stability test,the membrane reactor presents good methane conversion and chemical stability.
