Trans. Nonferrous Met. Soc. China 25(2015) 319-328 Mechanism analysis of ions interaction in MgCl2/LiCl solution and effect of lithium on ammonia precipitation products Jin TAN1, Zheng-ping WU1,2... that when the distance of Mg2+ and Li+ is 7-10 , the interaction energy is high and the trend of solvation is strong, which would make hydroxide ions easier to combine with hydrogen ions in ammonia......
of Technology, Beijing 100124, China) Abstract: Due to the difficulty of nitrogen removal in the mature landfill leachate, a combined process consisting of short-term nitrification sequencing batch reactor..., the ammonium and nitrite removal efficiency both reached over 98%, and total nitrogen volume removal rate was increased from 0.10 kg/(m3·d) to 0.75 kg/(m3·d). After domestication, mix the leachate......
La2Ce2O7 supported ruthenium as a robust catalyst for ammonia synthesisWenfeng Han,Zhi Li,Huazhang LiuInstitute of Industrial Catalysis, Zhejiang University of Technology摘 要:ammonia synthesis under conditions similar with industry. With La2Ce2O7 being calcinated at 700 or 800℃, the experimental results indicate that the Ru/La2Ce2O7 catalyst exhibits much higher......

. In Zn(II)-NH3-Cl--H2O system, the ternary complexes containing ammonia and chloride increase the zinc solubility in neutral solution. There are three zinc compounds, Zn(OH)2, Zn(OH)1.6Cl0.4 and Zn(NH3)2Cl2, on which the zinc solubility depends, according to the total ammonia, chloride and zinc concentration. These thermodynamic diagrams show the effects of ammonia, chloride and zinc......
IF钢氮含量控制技术研究李伟东1,孙群1,林洋1(1.辽宁省鞍山市鞍钢股份有限公司第二炼钢厂)摘 要:介绍了鞍钢第二炼钢厂几年来在生产IF钢过程中对于氮成分控制方面所做的探索和研究,总结出低氮钢的生产技术和防止增氮技术.低氮钢的生产工艺包括转炉冶炼工序提高铁水比,冶炼过程控制返干,冶炼终点减少补吹次数和时间,采用铁矿石造渣,可以显著地降低转炉冶炼终点的氮含量;RH-TB精炼工序处理前期提高脱碳速度,处理中期快速提高真空度,提高提升氩气流量和钢水循环量,处理后期控制钢水中的氧含量,同时必须保证钢水极低的硫含量.防......
