Trans. Nonferrous Met. Soc. China 31(2021) 2153-2164 Formation of arsenic-copper-containing particles and their sulfation decomposition mechanism in copper smelting flue gas Wen-ming YAO1, Xiao-bo... the sulfation of copper, leading to the in-situ decomposition of copper arsenate. In this process, gaseous arsenic was released, and thus the separation of arsenic and copper was realized. Key words: copper......
Sulfation behavior of CuO/γ-Al2O3 sorbent for the removal of SO2 from flue gasQingchun Yu1), Shichao Zhang2), Xindong Wang1), Jie Zhang3), and Zhenming Lu3) 1) School of Metallurgical and Ecological... sulfation kinetics and sulfation recycling. It was found that the Langmuir kinetic adsorption model described well the experimental data at the rapid sulfation region of the CuO/γ-Al2O3 sorbent......
of sulfation on Pd/Ce0.75Zr0.25O2, Pd/Ce O2-Ti O2 and Pd/Ce O2 was investigated. Physical structure and chemical properties of different catalysts were characterized by N2 adsorption, X-ray diffraction(XRD), CO chemisorption, X-ray photoelectron spectroscopy(XPS), Fourier transform infrared spectroscopy(FT-IR) and X-ray fluorescence(XRF). After 10 h SO2 sulfation, it was found that the decrement on CO......

铝败铝战李圣船摘 要:<正>2001年中国已成为全球最大的电解铝生产国.早在2009年国务院宣布在以后连续三年不再核准新建,扩建该领域内的项目,但中国电解铝的产能却如打开后的潘多拉魔盒,好似已没有谁能有办法来试图控制其扩大,致使全国电解铝的产量逐年攀升,2009年,电解铝的产量达1298.5万吨,2010年1565万吨,2011年1806万吨……据中国有色金属工业协会统计,2012年全国电解铝产量2027万吨,同比增长12%,产能利用率却只有85%左右.全年LME三个月期铝关键词:......
