基于水合物技术的模拟钢铁厂烟气中二氧化碳捕获研究Capture of Carbon Dioxide from Simulated Power Plant Flue Gas Based on Clathrate Hydrate Technology 摘要：近年来由于温室效应以及气候改变对人类生产生活的影响日益加剧，以CO2 为主的温室气体减排逐渐成为人们关注的焦点。目前 CO2排放主要来源于化石能源的燃烧，所以CO2 减排的首要措施就是捕获和掩埋钢铁厂烟气中的CO2。水合物法捕获 CO2 是一种新型分离技术， 它是利用烟气中 CO2 和 N2 生成水合物的相平衡条件的差异，选择性地使CO2 和水生成固态的水合物，从而与气相中的 N2 分离，该技术具有分离效率高、过程简单等优点。本文分别以四丁基溴化铵(TBAB) 、四丁基氟化铵 (TBAF) 以及环戊烷 (CP)为添加剂，测定了TBAB 和TBAF 存在时 CO2 以及模拟钢铁厂烟气 (CO2/N 2)生成水合物的相平衡条件，考察TBAB 、TBAF 以及环戊烷存在下CO2/N 2生成水合物的动力学特性以及CO2 分离性能，为开发高效快速、低能耗水合物法捕获烟气中CO2 工艺技术提供理论依据。 矚慫润厲钐瘗睞枥庑赖。关键词： 水合物； CO2 捕获；四丁基溴化铵；四丁基氟化铵；环戊烷；钢铁厂烟气；能耗Abstract: There are increasing concerns for greenhouse gas recently, especially for carbon dioxide emissions mitigation of the influence of global warming and climate change on human activities. The emissions of carbon dioxide primarily result from the combustion of fossil fuels and the main approach for CO2 emissions is carbon capture and sequestration. Hydrate-based capture of CO2 is a new separation technology, which is based on the differences of hydrate phase equilibrium conditions of CO2 and N2 and selectively engaged CO2 into the cages of hydrate. The technology is of high efficiency, simpleness and conveniency and so on. In this study, tetra-n-butyl ammonium bromide (TBAB), tetra-n-butyl ammonium fluoride (TBAF) and cyclopentane were chosen as additives for hydrate formation. The phase equilibrium conditions of CO2, simulate flue gas (CO2/N 2) hydrate...
