چکیده
Abstract In this work, characterization and kinetics of CO2 absorption in potassium carbonate (K2CO3) solution promoted by diethylenetriamine (DETA) were investigated. Kinetics measurements performed using a stirred cell reactor the temperature range 303.15–323.15 K total concentration up to 2.5 kmol m?3. The density, viscosity, physical solubility, diffusivity rate determined. reaction between K2CO3 + DETA examined. Pseudo-first order kinetic constants also predicted zwitterion mechanism. It was revealed that addition small amounts DETA K2CO3 results significant enhancement rate. activation energy found be 1.6 35.6 kJ mol?1, respectively. terms constant, showed better performance compared other promoters such as MEA, EAE, proline, arginine, taurine, histidine alanine.

Absorption with chemical reaction: evaluation of rate promoters effect on CO2 absorption in hot potassium carbonate solutions
The improving effect of rate promoters has been investigated by experiments at pilot plant scale in conditions close to the operating conditions of the top zone of a typical hot potassium carbonate industrial packed bed absorber. The evaluation of promoter enhancement factor has been done by successive experiments with absorption of CO2 into water, into carbonate solution and into promoted carb...
متن کاملIon Absorption by Shoot Tissue: Kinetics of Potassium and Rubidium Absorption by Corn Leaf Tissue.
The relative impermeability of the surfaces of leaves to water and mineral ions in solution is a condition upon which the life of terrestrial higher plants depends. However, for the investigator this feature imposes difficulties on attempts to make quantitative studies of the process of ion absorption by leaf tissue. The importance of this absorption process in the physiology of leaf cells has ...
متن کاملEffect of CO2 Partial Pressure on the Thermal Decomposition Kinetics of Zinc Carbonate Hydroxide (TECHNICAL NOTE)
In this work, the effect of carbon dioxide partial pressure on the calcination kinetics of high purity zinc carbonate hydroxide has been studied. Non-isothermal analysis has been performed on samples at different CO2 partial pressures by TGA and DTA. It has been found that the calcination behaviour of this material corresponds to the shrinking core model and the reaction mechanism is phase boun...
