Book Description
Recently, global warming and climate change problems have begun to receive attention globally. One of the urgent policies is to control greenhouse gas emissions to the atmosphere. Among the greenhouse gases, CO2 is considered to be a major contributor due to its abundance. The absorption of CO2 into chemical solvents is one of the mostpromising technologies for capturing CO2 due to its capability of handling large amounts of exhaust stream. One of the key parameters for this technology is to use effective solvents. A newly developed amino alcohol solvent, 4-(diethylamino)-2-butanol (DEAB), is now being considered as a promising alternative solvent for capturing CO2 due to its energy efficiency for regeneration and high absorption capacity. The primary focus of this research is on developing comprehensive reaction rate/kinetics models that take into account the coupling between the chemical equilibrium, mass transfer, and chemical kinetics of all possible chemical reactions for the absorption of CO2 into aqueous solutions of DEAB and blended MEA-DEAB in order to explore the potential of these new formulated solvents for capturing CO2 in terms of reaction kinetics. The fundamental knowledge required for the kinetics study, such as the physical solubility of CO2 (Henry's law constant), the physical diffusivity of CO2, the equilibrium solubility of CO2, and the CO2-amines equilibria, are also considered in this research. The physical solubility and physical diffusivity of CO2 in aqueous solutions of DEAB and blended MEA-DEAB were estimated via a N2O analogy, which consists of measuring the solubility and diffusivity of N2O instead of CO2. The developed predictive correlations for the solubility and diffusivity of N2O in these new formulated solvents provide good predictive results compared to the experimental results. The absorption capacity in terms of the equilibrium solubility of CO2 in aqueous solutions of DEAB was found to be very high (comparable with PZ) and higher than that of AMP, MDEA, MEA, and DEA. Furthermore, the equilibrium solubility of CO2 in an aqueous solution of blended MEA-DEAB was observed to be higher than that of MEA. This research also established the mathematical models for calculating the equilibrium solubility of CO2 in an aqueous solution of these new formulated solvents. The calculated CO2 equilibrium solubility results were found to fit well with the experimental results. Finally, the comprehensive reaction rate/kinetics models for CO2 absorption into aqueous solutions of DEAB and blended MEA-DEAB were successfully developed. The predicted CO2 absorption rates obtained from the models favourably fit with the experimental results. The reaction kinetics results show that: (i) the rate of CO2 absorption into DEAB is higher than that into MDEA, is comparable with that into AMP and DEA, and is lower than that into MEA and PZ, and (ii) the rate of CO2 absorption into blended MEA-DEAB is higher than that into MEA. Based on the results obtained from this research in terms of reaction kinetics and absorption capacity, it can be concluded that the aqueous solutions of DEAB and blended MEA-DEAB have good potential to be used as the alternative solvents for capturing CO2.
Calorimetry and Thermal Methods in Catalysis
Author: Aline AurouxPublisher: Springer Science & Business Media
ISBN: 3642119549
Category : Technology & Engineering
Languages : en
Pages : 569
Book Description
The book is about calorimetry and thermal analysis methods, alone or linked to other techniques, as applied to the characterization of catalysts, supports and adsorbents, and to the study of catalytic reactions in various domains: air and wastewater treatment, clean and renewable energies, refining of hydrocarbons, green chemistry, hydrogen production and storage. The book is intended to fill the gap between the basic thermodynamic and kinetics concepts acquired by students during their academic formation, and the use of experimental techniques such as thermal analysis and calorimetry to answer practical questions. Moreover, it supplies insights into the various thermal and calorimetric methods which can be employed in studies aimed at characterizing the physico-chemical properties of solid adsorbents, supports and catalysts, and the processes related to the adsorption desorption phenomena of the reactants and/or products of catalytic reactions. The book also covers the basic concepts for physico-chemical comprehension of the relevant phenomena. Thermodynamic and kinetic aspects of the catalytic reactions can be fruitfully investigated by means of thermal analysis and calorimetric methods, in order to better understand the sequence of the elemental steps in the catalysed reaction. So the fundamental theory behind the various thermal analysis and calorimetric techniques and methods also are illustrated.
