摘要

考察了CoO/MgO 固溶体催化剂在BaCo_0.7Fe_0.2Nb_0.1O_3−σ(BCFNO)透氧膜反应器内, 对焦炉煤气(coke oven gas, COG)中甲烷部分氧化重整(partial oxidation of methane, POM)的催化性能. 首先, 研究了CoO/MgO固溶体催化剂合成的工艺条件; 然后, 考察了焦炉煤气流量和空气流量对重整性能的影响, 并对比分析了NiO/MgO固溶体、CoO/MgO 固溶体催化剂和0.5%RuCoO/MgO 催化剂的重整性能. 实验结果表明, NiO/MgO 固溶体催化剂的重整性能优于CoO/MgO 固溶体催化剂. 但经Ru贵金属修饰后, CoO/MgO 固溶体催化剂的催化活性得到了很大提高.

Abstract

The catalytic reform performance of CoO/MgO solid solution catalyst for partial oxidation of methane (POM) in a coke oven gas (COG) in BaCo_0.7Fe_0.2Nb_0.1O_3−σ(BCFNO) oxygen permeable-membrane reactor was investigated. Synthesis technology of the CoO/MgO solid solution catalyst is analyzed. The effect of COG flow rate and air flow rate on the reform performance is discussed. For comparison, the reform performance of NiO/MgO, CoO/MgO and 0.5% RuCoO/MgO solid solution catalyst were studied. The results indicate that the NiO/MgO catalyst is superior to CoO/MgO solid solution catalyst, and the catalytic activity of CoO/MgO with the addition of Ru is greatly improved.

Key words： catalyst; coke oven gas (COG); oxygen permeation membrane; partial oxidation of methane (POM); hydrogen
