Research on Development Situation of Ferrous Metal Resources in China

Task Group for the Strategic Research on Great Power of Ferrous Metal Mineral Resources

Strategic Study of CAE 2019, Volume 21, Issue 1,   Pages 97-103 doi: 10.15302/J-SSCAE-2019.01.014

Abstract:

 As a forerunner of the supply-side structure reform, China’s iron and steel industry actively resolves its overcapacity. More than 1.2×108 t of excessive steel production capacity has been resolved between 2016 and 2017, and 1.4×108 t of illegal production capacity, such as “substandard steel” has been eliminated. As the global iron and steel industry is currently in the excess production capacity cycle, China's steel consumption has developed from a sustained growth phase to a peak value platform area. Meanwhile, both the crude steel consumption intensity per unit GDP and that per unit investment has decreased. It is expected that the consumption demand and output of crude steel in China will reach 6×108-6.5×108 t and 6.5×108-7.0×108 t by 2025, respectively; and these same items will reach 5.3×108-6.0×108 t and 5.9×108-6.5×108 t by 2030, respectively. Meanwhile, the supply of steel scrap resources in China will increase rapidly, and the sufficient steel scrap resources will become a strong support for China’s iron and steel industry. The structure of iron resources will also be greatly changed, and the demand for international iron ore resources will decrease gradually. All the changes are important in promoting ecological civilization construction and green development.

Enhanced carbon tetrachloride degradation by hydroxylamine in ferrous ion activated calcium peroxide

Wenchao Jiang, Ping Tang, Zhen Liu, Huan He, Qian Sui, Shuguang Lyu

Frontiers of Environmental Science & Engineering 2020, Volume 14, Issue 2, doi: 10.1007/s11783-019-1197-1

Abstract: Complete CT degradation was achieved by employing HA to CP/Fe(II)/FA process. Quantitative detection of Fe(II) regeneration and HO• production was investigated. Benzoic acid outcompeted FA for the reaction with HO•. CO2•− was the dominant reductive radical for CT removal. Effects of solution matrix on CT removal were conducted. Hydroxyl radicals (HO•) show low reactivity with perchlorinated hydrocarbons, such as carbon tetrachloride (CT), in conventional Fenton reactions, therefore, the generation of reductive radicals has attracted increasing attention. This study investigated the enhancement of CT degradation by the synergistic effects of hydroxylamine (HA) and formic acid (FA) (initial [CT] = 0.13 mmol/L) in a Fe(II) activated calcium peroxide (CP) Fenton process. CT degradation increased from 56.6% to 99.9% with the addition of 0.78 mmol/L HA to the CP/Fe(II)/FA/CT process in a molar ratio of 12/6/12/1. The results also showed that the presence of HA enhanced the regeneration of Fe(II) from Fe(III), and the production of HO• increased one-fold when employing benzoic acid as the HO• probe. Additionally, FA slightly improves the production of HO•. A study of the mechanism confirmed that the carbon dioxide radical (CO2•−), a strong reductant generated by the reaction between FA and HO•, was the dominant radical responsible for CT degradation. Almost complete CT dechlorination was achieved in the process. The presence of humic acid and chloride ion slightly decreased CT removal, while high doses of bicarbonate and high pH inhibited CT degradation. This study helps us to better understand the synergistic roles of FA and HA for HO• and CO2•− generation and the removal of perchlorinated hydrocarbons in modified Fenton systems.
