“…An increase in the initial glycerol concentration from 0.3 to 1.5 M, a full transformation of glycerol, was achieved with the production of 42% of glycolic acid, glyceric acid, and formic acid (15%). CO 2 production was also reported ( Tavera Ruiz et al, 2021 ).…”

The glycerol oxidation reaction was developed leading to selective catalysts and optimum conditions for the production of carboxylic acids such as glycolic acid. However, carboxylic acids are produced in highly diluted mixtures, challenging the recovery and purification, and resulting in high production costs, polymerization, and thermal degradation of some of the products. The protection of the acid function by esterification reaction is one of the most promising alternatives through reactive distillation (RD); this technique allows simultaneously the recovery of carboxylic acids and the elimination of most part of the water. The reactive distillation, experimental and simulation, of glycolic acid was performed, based on kinetic and thermodynamic models developed. For the thermodynamic model, binary parameters of the missing couples were determined experimentally, and the non-random two-liquid (NRTL) model was selected as the most suitable to represent the binary behavior. The kinetic study of the esterification in the presence of homogeneous and heterogeneous catalysis concluded that the heterogeneous reaction can be accurately described either by a pseudo-homogeneous model or the Langmuir–Hinshelwood (L-H) adsorption model. Reactive distillation was conducted in a distillation column filled with random packing sulfonated ion-exchange resin, Nafion NR50®, or with extruded TiO2-Wox. The conversion rate of glycolic acid in reactive distillation increases from 14% without catalyst to 30% and 36% using Nafion NR50® and TiO2-Wox, respectively. As opposed to the batch reactor study, the conversion rate of glycolic acid was better with TiO2-Wox than with sulfonated ion-exchange resin. The better performance was related to an increase in the hydrodynamics inside the column. Tests using water in the feed confirm the hypothesis by increasing the conversion rate because of the decrease in the mass transfer resistance by reducing the average diffusion coefficient. The simulation of the reactive distillation column with ProSim® Plus showed that the yield of the ester increased operating at a low feed rate with reactive stripping. In the presence of water in the feed, nonreactive stages are required, including an enrichment region to separate water vapor.

“…In 2021, the output of GA in China was approximately 24,000 tons, and it is expected to reach 46,000 tons by 2030. GA can be obtained by natural extraction, chemical synthesis, and biological fermentation, of which chemical synthesis is the main way. , During the chemical preparation of GA, some impurities, such as inorganic salts, are generally produced, which affects the downstream processing and quality of crystalline GA. Thus, it is necessary to remove the impurities from a GA solution.…”

A two-dimensional transport dispersive (TD) model, based on the Navier–Stokes equation, describing an energy conservation of fluid motion, and a one-dimensional TD model, were built to describe the diffusions of glycolic acid (GA) and NaCl in the axial and radial directions in a preparative column. The elution and breakthrough curves of GA and NaCl were simulated with the models, and the instantaneous concentrations of GA and NaCl in the column were further studied. The results indicated that the two-dimensional TD model simulated the elution curve of GA, whereas that of NaCl could be simulated with the one- or two-dimensional TD models. The parameters of the models were obtained by combining the empirical and inverse methods, which enhanced the simulation accuracy. The external transfer diffusion was the rate-controlling step during adsorption of GA due to a Biot constant less than 10. Moreover, the concentration of NaCl was slightly higher than that of GA at the same axial position in the column, and the diffusion fronts of GA and NaCl were in a parabolic form. On increasing the column temperature, the retention time of GA and the resolution gradually decreased, whereas the diffusion of NaCl did not change appreciably. The breakthrough volumes of both NaCl and GA remained unchanged, and the total transfer coefficient of GA showed a downward trend overall within the experimental range.

“…To achieve the goals of the Paris Agreement, global anthropogenic CO 2 emissions should be zero by 2050, and although major CO 2 sources come from power, steel, and cement industries [1,2], efforts from all areas of society will be needed. However, the challenge involves unequal abatement costs across sectors.…”

Exploring the potential of utilizing CO2 for commercial purposes is a promising opportunity, especially in light of the growing research efforts towards CO2 capture, storage, and utilization as well as green H2 production. This review article delves into catalyst features and other technological aspects of a plausible process for the indirect conversion of CO2 into glycolic acid, which involves the following steps: CO2 capture, water electrolysis, CO2 hydrogenation to methanol, catalytic oxidation to formaldehyde, and formaldehyde carbonylation to glycolic acid. We adopt an industrial perspective to address this challenge effectively, thoroughly evaluating different processing alternatives with emphasis on the catalytic systems to optimize glycolic acid production performance.
