The existing chemical synthesis processes of polymeric ferric sulfate (PFS) were summarized and analyzed in this thesis, the results have showed that catalytic oxo-synthesis can still be used as a practicable chemical synthesis of PFS and NaNO2 can be used as a kind of catalyst which has better performance.
本论文对已有的聚合硫酸铁化学合成工艺进行的总结和分析表明,催化氧化法仍是一种实用性较强的合成方法,而NaNO_2仍可作为一种性能优良的催化剂使用。
补充资料:规模经济/规模不经济
规模经济/规模不经济:规模经济和规模不经济用来说明厂商产量变动从而规模变动与成本之间的关系。对于一个生产厂商而言,如果产量扩大一倍,而厂商的生产成本的增加低于一倍,则称厂商的生产存在着规模经济;如果产量增加一倍,而成本的增加大于一倍,则生产存在着规模不经济。
