过渡金属添加剂对煤热解脱硫的影响
, PP. 641-647
Keywords: 过渡金属添加剂,高硫焦煤,热解,焦化,脱硫
Abstract:
？利用坩埚焦考察了过渡金属添加剂fe、cr和mn的不同形态在焦化过程中对高硫焦煤中硫脱除的影响,并通过固定床热解实验考察了不同气氛下添加剂对煤热解脱硫及含硫化合物逸出的影响。结果表明,不同金属添加剂对煤中硫形态有不同影响,氧化性较高的fe3+降低了煤中黄铁矿硫的含量,而其他金属添加剂对煤中硫形态影响不大。在模拟焦化过程中,铬系添加剂提高了热解脱硫率,而铁系和锰系添加剂降低了脱硫率;负载cr3+的介休煤在不同气氛下的热解表明,氮气抑制了cr的脱硫作用,显著地减少了含硫气体的生成量,并使煤中易脱除硫转化为稳定的有机硫;还原性气氛有利于cr3+添加剂的脱硫作用,显著地增加了含硫气体的生成量;焦炉气和氢气下添加剂对热解脱硫及煤热解过程中含硫气体逸出的影响相似,焦炉气可以作为提高过渡金属添加剂脱硫性能的反应气体。
