Another example of this acid attack is reported by LI et al [8] where a severe corrosion issue of cement-based structures by sulfuric acid was observed... indicated that the acid resistance of concrete can be noticeably enhanced [15-17]. TORRI et al [15] investigated the acid resistance of mortar samples and found that the 10% substitution of cement......
电池组分复杂,在机械处理过程中相互干扰,不可能实现各个组分的完全分离.SHIN等[9]对废旧LiCoO2电池放电后通过控制破碎粒径筛分得到不同粒径范围的碎屑,对这些碎屑成分进行分析得出Fe和Al的含量随着碎屑粒径降低而降低,而Co的含量呈现出相反的变化趋势. 在机械破碎分选过程中,为了提高活性物质粉末的回收率,必须通过2次甚至3次破碎降低碎屑粒径的方式实现,但这样势必会增大分选难度,降低分离组分的.../L,液固质量比为15:1,溶解温度为60 ℃,反应时间为60 min条件下,获得Al的溶出率为97.8%,铜溶出率为64.7%.破坏集流体铝箔的方法具有能耗低,操作性强等优势,但集流体铝箔以离子的形式进入溶液中,需要进一步进行回收处理.此外,该过程需要大量的碱溶液,为防止碱液产生二次污染,需要进行中和处理,这样将需要额外的成本开销.由于碱溶解过程中黏结剂并没有被破坏,过滤烘干得到的活性物质仍然是......
Fe2O3/Al2O3载氧体可以改善载氧体的稳定性[65],Si加入Fe2O3/Al2O3载氧体可以生成Si-Al-O结构有利于载体的稳定[66].助剂的加入也可以改善载氧体的反应活性,HAFIZI等[67]使用Ca改性Fe2O3/Al2O3载氧体,在700 ℃左右CH4的转化率达到100%,并且比较了Ce改性与Ca改性载氧体,发现助剂类型影响载氧体的活性,稳定性以及抗积碳性能,使用5%的Ce和Ca助剂就...CH4/CO2转化工艺的实现需要设计能够实现铁基载氧体深度还原,燃料高效转化的燃料反应器,CH4和CO2需要转化率在大规模反应装置进一步证实. 参考文献: [1] 苏小平, 王力, 杨武, 等. 甲烷化学链重整制合成气的研究进展[J]. 地下水, 2017, 39(4): 198-202.
