祝贺课题组马琎晨博士后的论文:Fate of Mercury in Volatiles and Char during in Situ Gasification Chemical-Looping Combustion of Coal (煤化学链燃烧中重金属汞在热解和煤焦两阶段中的迁移)被环境领域顶级期刊Environmental Science& Technology (IF=7.864)收录。赵海波教授为通讯作者,马琎晨为第一作者。
本工作以天然铁矿石氧载体为研究对象,巧妙地辨识了煤中重金属在实际化学链燃烧中热解阶段和气化阶段不同的迁移释放特性,分析了氧载体对汞形态的转变作用。以煤灰和氧载体完全隔离,精确研究固体汞的存在位置和赋存形态。本研究有助于进一步建立化学链燃烧中重金属富集减排的控制策略。该工作资助项目为:国家重点研发计划项目(2016YFB0600801)。
