采用固相合成法制备了BaCo0.7Fe0.3-xNbxO3-δ(x=0.08～0.14)材料。铌掺杂量的改变能显著影响材料的相结构稳定性、化学稳定性、晶粒组织及透氧性能。随着铌掺杂量的提高,材料的氧空位形成能力增强、晶粒组织得到细化,从而提高了材料的透氧能力。不同烧结时间下BaCo0.7Fe0.3-xNbxO3-δ透氧膜片透氧能力的测试结果表明晶粒组织的细化能够提高BaCo0.7Fe0.3-xNbxO3-δ材料的透氧能力。

对焦炉煤气甲烷部分氧化重整热力学进行分析,考察反应温度、CH4/O2摩尔比及水蒸气加入量等因素对重整性能的影响,并分析焦炉煤气原始氢含量对其部分氧化重整性能的影响.分析结果表明甲烷转化率均随CH4/O2摩尔比和水蒸气加入量的增大以及反应温度的升高而增大.在CH4/O2摩尔比1.7-2.1,温度825-900℃及压力1.01×105Pa的反应条件下,可得较好重整性能;甲烷转化率,氢及一氧化碳的选择性分别为91.0%-99.9%,87.0%-93.4%和100%-107%,重整后得到的氢量增大到原始氢量的1.95-2.05倍,每摩尔焦炉煤气消耗的热量仅为2.94J,同时得出在CH4/O2摩尔比2,温度825-900℃及1.01×105Pa条件下,往焦炉煤气内添加体积分数为2%-4%的水蒸气时重整性能得到较大提高;重整后甲烷转化率、氢及一氧化碳选择性分别由92.6%、87.2%、104%增大到98.6%、96.4%、107%.并在BaCo0.7Fe0.2Nb0.1O3-δ透氧膜反应器上研究NiO/MgO固溶体催化剂焦炉煤气部分氧化重整性能.结果表明该重整反应效果较好,于875℃下获得***-1透氧量,95%甲烷转化率及80.5%氢和106%一氧化碳选择性.且所得实验结果与热力学分析结果符合较好,表明NiO/MgO固溶体催化剂有较好的催化重整性能.

混合导体固体透氧膜与POM制氢工艺相耦合,可以较大幅度地降低制氢成本.由于透氧膜在高温、强还原性气氛下工作,仅仅具有较高的透氧能力并不能满足实际应用需求,还必须具有较高的化学稳定性.通过O2-TPD,CO2-TG及透氧实验研究了两种透氧能力最高的膜材料BaCo0.7Fe0.2Nb0.1O3-δ及Ba0.5Sr0.5Co0.8Fe0.2O3-δ.研究发现,由于Ba0.5Sr0.5Co0.8Fe0.2O3-δ钙钛矿中A位的Sr2+被Ba2+取代及B位的Co4+部分被Nb5+取代,有效地提高了BaCo0.7Fe0.2Nb0.1O3-δ钙钛矿材料的化学稳定性.
