Abstract

Solubility of CO2 in molten Li2CO3-LiCl was measured by using a pressure differential method and the enthalpy change of the solution was calculated on that basis. The relationships between the solubility and the enthalpy change, and the temperature and the composition of the melts were discussed. The results showed that when the temperature was 873-923K and the Li2CO3content was 10-50 mol%, the solubility of CO2 increased with decreasing temperature and/or increasing Li2CO3 content.The maximum solubility was 3.965 ? 10?7gCO2/gmelt at 873Kwhen the content of Li2CO3 was 50 mol%. The solution of CO2was exothermic. With increasing temperature and Li2CO3content,more enthalpy was needed for CO2 solution.

CO2在熔融Li2Co3-LiCl中的溶解度

采用压差法测定CO2在熔融Li2CO3-LiCl中的溶解度，并在此基础上计算溶液的焓变。讨论了熔体的溶解度与焓变、温度和组成之间的关系。结果表明:当温度为873 ~ 923k, Li2CO3含量为10 ~ 50 mol%时，CO2的溶解度随温度的降低和Li2CO3含量的增加而增加;最大溶解度为3.965 ?10 ?当Li2CO3的含量为50 mol%时，在873k下熔化7gCO2/g。二氧化碳的溶液是放热的。随着温度的升高和li2co3含量的增加，CO2溶液所需焓增大。

期刊介绍： University of Belgrade, Technical Faculty in Bor, has been publishing the journal called Journal of Mining and Metallurgy since 1965 and in 1997 it was divided in two independent journals dealing with mining and metallurgy separately. Since 2009 Journal of Mining and Metallurgy, Section B: Metallurgy has been accepted in Science Citation Index Expanded. Journal of Mining and Metallurgy, Section B: Metallurgy presents an international medium for the publication of contributions on original research which reflect the new progresses in theory and practice of metallurgy. The Journal covers the latest research in all aspects of metallurgy including hydrometallurgy, pyrometallurgy, electrometallurgy, transport phenomena, process control, solidification, mechanical working, solid state reactions, materials processing, surface treatment and relationships among processing, structure, and properties of materials.
