在目前的工作中，在低温和氨浓度范围从0.1到约7 kmol m-3的搅拌槽反应器中研究了二氧化碳吸收到氨水溶液中。吸收实验是在遵守所谓的伪一级传质制度的条件下进行的，因此可以推导出二氧化碳和氨之间反应的动力学。根据公认的两性离子交换机理对结果进行了解释。
In the present work the absorption of carbon dioxide into aqueous ammonia solutions has been studied in a stirred cell reactor, at low temperatures and ammonia concentrations ranging from 0.1 to about 7 kmol m−3. The absorption experiments were carried out at conditions where the so-called pseudo first order mass transfer regime was obeyed–and hence the kinetics of the reaction between carbon dioxide and ammonia could be derived. The results were interpreted according to the well-established zwitterion mechanism.
