摘要

利用固相法合成了3种钙钛矿型复合氧化物Fe2O3-CaTixM1-xO3，研究了其结构、晶型和氧化还原活性。在固定床反应器中考察了该氧化物对两步法甲烷催化氧化制合成气及水分解制氢的活性及选择性。X射线衍射结果表明3种钙钛型复合氧化物均由正交晶系钙钛矿相和赤铁矿相组成。3种钙钛矿复合氧化物对甲烷的氧化活性顺序为Fe2O3-CaTi0.85Ni0.15O3 >Fe2O3-CaTi0.85Co0.15O3 >Fe2O3-CaTi0.85Fe0.15O3。固定床反应结果表明，以Fe2O3-CaTi0.85Ni0.15O3为氧载体催化剂，CH4转化率可达96%，CO和H2产率达71%，同时水分解反应的转化率为40%。利用Aspen Plus®对Fe2O3-CaTi0.85Ni0.15O3在混合太阳能氧化还原过程的效率及合成油和H2产率进行了模拟。模拟计算结果证明基于复合氧化物的混合太阳能氧化还原过程可以有效提高CH4利用率。

Abstract

Structural

crystalline phase

and redox properties of three composite oxides with a general formula of Fe2O3-CaTixM1-xO3 were investigated. Integral and differential bed reactors were used to investigate methane partial oxidation and water-splitting reactions. In their oxidized form

all three composites consisted of orthorhombic perovskite phase and hematite phase. Activities for methane partial oxidation followed the sequence: Fe2O3-CaTi0.85Ni0.15O3 > Fe2O3-CaTi0.85Co0.15O3 > Fe2O3-CaTi0.85Fe0.15O3. Fixed bed results indicated that Fe2O3-CaTi0.85Ni0.15O3 was capable of converting 96% CH4 with syngas yield of 71%. Steam to hydrogen conversion in water-splitting was 40%. ASPEN Plus® simulations indicated that Fe2O3-CaTi0.85Ni0.15O3

when used in the hybrid solar-redox process

could signficantly enhance methane utilization efficiency for liquid fuel and H2 co-production.
