Sulfur poisoning mechanism of three way catalytic converter and its grey relational analysisCAI Hao(蔡皓)1, LIU Ya-fei(刘亚飞)1, GONG Jin-ke(龚金科)1 , E Jia-qiang(鄂加强)1, GENG Yu-he(耿玉鹤)2, YU Li-ping(余立平)1.... This provides an important reference to the improvement of activity design of TWC, and may provide guidance for the condition design and optimization of TWC.Key words:sulfur poisoning; three-way catalytic......
Influence of Rare Earths on Improve Impact Property of Structural Alloy Steel with Extra Low Sulfur and Oxygen Lin Qin1,Guo Feng2 (1.Physical Chemistry Department, University of Science... and cerium on impact property of structural alloy steel with extra low sulfur and oxygen was studied by impact test and microanalysis. The results showed that rare earths increased impact power of the steel......
J. Cent. South Univ. (2017) 24: 1736-1744 DOI: https://doi.org/10.1007/s11771-017-3581-y Inhibition mechanism between sodium (Na3AlF6) and sulfur on coke reactivity ZHONG Qi-fan(仲奇凡)1, XIAO Jin(肖劲)1... (Na3AlF6) and sulfur on coke reactivity was investigated by simulating petroleum coke with low-impurity pitch coke and by impurity doping. The mechanism was discussed by scanning electron microscopy......
Reduction of SO2 to elemental sulfur over rare earth-iron catalysts邓庚凤1,姜坤1,曹霞2,廖春发11. School of Materials and Chemical Engineering,Jiangxi University of Science and Technology2. Nanchang Engineering and Research Institute of Nonferrous Metals摘 要:With coal gas as a reducing agent, the catalytic reduction of SO2 to sulfur in the flue gas produced......

the massive, veinlet, disseminated, banded, miarolitic, biological residual and brecciated structure. In addition, the sulfur isotopes of the metal sulfide were analyzed. The results show.... This indicates that the sulfur isotope composition has large difference between the different deposits. The sulfur isotope values of the Dafulou ore are concentrated relatively, yet are dispersed......
XPS characteristics of sulfur of bio-oxidized arsenic-bearing gold concentrate and changes of surface nature of bio-oxidation residue YANG Hong-ying(杨洪英), GONG En-pu(巩恩普), YANG Li(杨 立), CHEN..., the chemical state change of sulfur is a complex and key factor. It is not only an indicator of the extent and intensity of the bio-oxidation, but also controls the property of bio-leaching medium......
J. Cent. South Univ. Technol. (2011) 18: 1924-1929 DOI: 10.1007/s11771-011-0924-y Influence of sulfur content in raw materials on oxidized pellets CHUN Tie-jun(春铁军), ZHU De-qing(朱德庆), PAN Jian(潘建... of sulfur content in raw materials on oxidized pellets was studied. The results show that most sulfur exists in the form of elementary sulfur in pyrite cinder, and over 95% sulfur is removed in producing......
