Optimal Absorbent Evaluation for the CO2 Separating Process by Absorption Loading,Desorption Efficiency,Cost, and Environmental Tolerance

The CO₂ absorption capacities of potassium glycinate, potassium sarcosinate (choline, proline), mono-ethanolamine (MEA), and tri-ethanolamine were evaluated to find the optimal absorbent for separating CO₂ from gaseous products by a CO₂ purification process. The absorption loading, desorption efficiency, cost, and environmental tolerance were assessed to select the optimal absorbent. MEA was found to be the optimum absorbent for separating the CO₂ and H₂ mixture in gaseous product. The maximum absorption loading rate was 0.77 mol CO₂ per mol MEA at temperature of 20°C and absorbent concentration of 2.5 mol/L, whereas desorption efficiency was 90% by heating for 3 h at 130°C. MEA was found to be an optimal absorbent for the purification process of CO₂ during gaseous production.

贸易自由化对我国环境的影响——基于ACT模型的实证研究

近年来我国对外贸易发展迅速，但伴随而来的环境污染问题也越来越严重。学术界对我国贸易与环境问题进行了多方面研究，但并未得到一致的结论。文参考ACT模型，试图将贸易自由化对我国环境的影响从经济发展对我国环境的整体效应中分离出来进行研究。本文采用panel数据对我国1992-2004年期间贸易自由化的环境效应进行了实证分析，结果表明：贸易自由化对我国环境消极的规模效应和结构效应远远超过了积极的技术效应，即贸易自由化使我国环境恶化。这主要归因于我国粗放型的经济增长方式以及不完善的环境法规。要改善其不利影响，我国应采用法律和经济措施相结合的办法，从而达到减少贸易的规模效应、改变现有贸易结购以及加强其技术效应的目的。
