固体碳的CO_2气化反应(C+CO_2=2CO),即逆Boudouard反应,是制约固体氧化物直接碳燃料电池(solid oxide direct carbon fuel cell,SO-DCFC)性能的关键反应之一。文章在比较煤焦和担载酸活化钢渣的煤焦的逆Boudouard反应性的基础上,研究比较了以二者为燃料的SO-DCFC的电化学性能。结果表明,酸活化钢渣催化剂使煤焦的逆Boudouard反应的起始温度降低了240℃,在800℃时的CO生成速率提高了4倍;在电化学性能上,酸活化钢渣催化剂使电池在850℃时的峰值功率密度从67.4mW·cm~(-2)提升到200.4mW·cm~(-2),燃料利用率从41.5%提高至79.6%。
【英文摘要】
The CO_2 gasification reaction of solid carbon(C+CO_2=2 CO),i.e.the reverse Boudouard reaction,is one of the key reactions determining the performance of solid oxide direct carbon fuel cells(SODCFC).Based on the comparison study of the reverse Boudouard reactivity of coal char and that loaded with acid-activated steel-slag catalyst,the electrochemical performance of DC-SOFC fuelled with the two fuels was investigated comparatively.The results showed that the acid-activated steel-slag catalyst reduced240℃ of...
