摘要
(CN103396835B) 本​发明​提供​了​一种​污泥​同时​制备​清洁​气体燃料​和​吸附剂​的​方法,其​步骤​为:向​污泥​浆​中​依次​添加​含铁​氧化剂​和​钙​基​调节剂,搅拌​混合​并​进行​机械​脱水​得到​脱水​污泥;对​脱水​污泥​经​破碎​后​进行​水蒸气​气化,制得​富含​H2、CO、CH4​的​清洁​气体燃料,气化​所得​固体​产物​即为​污泥​灰​基​吸附剂。本​发明​从​污泥​处理​处置​及​资源​利用​一体化​的​角度​出发,将​改善​污泥​气化​特性、提高​固体​产物​吸附​活性​过程​植入​复合​调理​脱水​过程,采用​湿​法​混合​方式​使​具有​催化​活性​的​含铁​氧化剂​和​钙​基​调节剂​在​污泥​颗粒​中​分布​更加​均匀,利用​二者之间​的​协同​效应​提高​气化​过程中​气体燃料​的​生成量​和​固体​产物​的​催化​活性,并​抑制​整个​过程中​污染物​的​释放,实现​了​低成本、低​能耗、低污染、高产量​的​污泥​利用。
