“…The second publication in the same series has highlighted the work on toxicity evaluation and formation mechanism based on a combination of condensation, dehydration, and oxidation of aldehydes of pyrazine and its derivatives claimed as newly found MEA degradation products (Rey et al, 2013). Mechanism studies of more MEA-based degradation products in the group of amides and nitrogen-based heterocyclic compounds have been added to the work in this research program (Gouedard et al, 2014). It is clear from this recent work that even MEA still requires more study to fully understand its degradation chemistry and required for evaluation of the amine toxicity from emissions.…”

Greenhouse Gas Control (2015), http://dx.Keywords: Recent development of PCC process Design and modeling Solvent development Post Build Operations Solvent chemistry Solvent management Mass transfer with reaction a b s t r a c tCurrently, post-combustion carbon capture (PCC) is the only industrial CO 2 capture technology that is already demonstrated at full commercial scale in the TMC Mongstad in Norway (300,000 tonnes per year CO 2 captured) and BD3 SaskPower in Canada (1 million tonnes per year CO 2 captured). This paper presents a comprehensive review of the most recent information available on all aspects of the PCC processes. It provides designers and operators of amine solvent-based CO 2 capture plants with an in-depth understanding of the most up-to-date fundamental chemistry and physics of the CO 2 absorption technologies using amine-based reactive solvents. Topics covered include chemical analysis, reaction kinetics, CO 2 solubility, and innovative configurations of absorption and stripping columns as well as information on technology applications. The paper also covers in detail the post build operational issues of corrosion prevention and control, solvent management, solvent stability, solvent recycling and reclaiming, intelligent monitoring and plant control including process automation. In addition, the review discusses the most up-to-date insights related to the theoretical basis of plant operation in terms of thermodynamics, transport phenomena, chemical reaction kinetics/engineering, interfacial phenomena, and materials. The insights will assist engineers, scientists, and decision makers working in academia, industry and government, to gain a better appreciation of the post combustion carbon capture technology.

A novel oxygen-driven method has been developed for low-cost, large-scale, and high-efficiency production of nitrogen-doped carbon dots (N-C-dots) by bubbling pure oxygen into monoethanolamine (MEA) under heating conditions. We find that the addition of pure oxygen significantly increases the reaction rate, and makes feasible one-pot gram scale fabrication (3.36 g) of highly photoluminescent N-C-dots in a couple of hours (2.0 h). With an instantaneous nucleation and gradual growth mechanism, precise control over the particle size of the N-C-dots from 2.0 to 16.1 nm is achieved by simply prolonging the heating time from 0.5 to 4.0 h. The as-prepared N-C-dots contain aromatic CN heterocycles in the core and have plentiful hydrophilic groups on the surface. Practically, the oxygendriven method can be used to synthesize fluorescent N-C-dots from other alkanolamines such as diethanolamine (DEA) and triethanolamine (TEA), which shows general universality. Due to the strong up-conversion photoluminescence, good aqueous dispersibility, high photostability, excellent biocompatibility, and low cytotoxicity, the N-C-dots are demonstrated to be promising two-photon probes for high contrast bioimaging applications.

In this contribution, the development of a process for the synthesis of potentially highly valuable polymeric products from the reaction of waste glycerol with ammonia is reported for the first time. The polymers were the result of a single step, continuous gas phase process, catalysed by an alumina-supported iron catalyst, operating under relatively mild reaction conditions. The solid product was characterised using 1D and 2D NMR spectroscopy, FTIR spectroscopy, qualitative chemical tests and elemental analysis. Characterisation revealed building blocks with unsaturated, amido and ester functionalities shaping a mixture of polymers. Nitrogen atoms were present in the main chain of the resultant polymers. NMR analyses of the polymer denotes the formation of structural defects such as unsaturation and branching; while the partial solubility of the polymer in solvents such as CDCl 3 and THF is indicative of the formation of cross-linked structures. Insights into the mechanism of formation of these functional groups were based on the liquid and gas phase product distribution. Polymers with chain structures similar to those synthesised in this work are currently manufactured from fossil fuels and are widely used in biomedical applications not 2 only because of their architecture but also due to their response to changes in pH and temperature.
