叙述了在1000氨合成塔技术改造中,采用NC型二轴一径塔内件、混装球形催化剂、分层还原方案、聚结式高效油分内件、优化提温型流程及主副线遥控调节等项新技术。
Through the distribution characteristics of Fe, Mn and S, it is found their cycle is doubly controlled by redox boundary layer and sedimentwater interface, and FeMn forms redox cycle surrouding sedimentwater interface with the force of organic matters degradation.
对阳宗海沉积物中铁、锰、硫的分布特征进行了分析,说明阳宗海沉积物早期成岩过程中铁、锰的循环受到氧化还原边界层和沉积物-水界面的双重控制。
Effects of reducing agents on NO reduction over Ag/Al_2O_3 catalyst;
还原剂对Ag/Al_2O_3催化剂上NO还原的影响
The results showed that NO reduction and NO oxidation.
结果表明:NO还原和氧化在其脱除过程中同时共存,当NO,N2,O2,H2O和CO2的体积浓度分别为200×10-6,80%,5%,6%和9%时,NO氧化所占的比例比NO还原的大很多;脉冲频率增大导致NO还原率和氧化率均增大;H2O浓度增大导致HNO3浓度增大,表明NO氧化所占的比例随H2O浓度增大而增大。
Combustion experiments on Shenmu bituminous coal and Geliping blind coal were carried out in a high-temperature horizontal twin-tube quartz stove,and NO volume fraction was measured in real-time during the combustion to investigate the effect of magnesium acetate on NO reduction.
