Fe-P-O体系催化剂上甲烷氧化偶联反应的浓度强制周期振荡研究

A study on forced concentration oscillations of oxidation coupling of methane over Fe-P-O catalyst

采用非稳态强制浓度周期振荡操作,对Fe-P-O体系催化剂上甲烷氧化偶联(OCM)反应的影响进行探讨.采用了三种浓度振荡反应形式,均使OCM反应与稳态操作相比有不同程度的改善,表明强制浓度振荡操作对OCM催化过程有强化作用.

In this paper, forced concentration oscillations of oxidation coupling of methane (OCM) over Fe-P-O catalyst were studied. Three different periodic operations were used. Compared with steady-state operations, effective increases of CH4 conversion a nd C2 yield were observed. It has demonstrated that forced concentration oscillations often provide significant efficiency enhance-ment of OCM catalytic process.
