“…Since the process is highly exothermic, temperature control is key to ensure good selectivity, so the reactors are typically designed with circulation of saturated water for generation of high-pressure steam, usually with the reaction occurring within tubes filled by the catalyst [89]. The catalyst choice is crucial because other reactions in parallel and in sequence can occur, reducing selectivity to formaldehyde formation.…”

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.

Although the absorption of formaldehyde is a crucial stage within its production process, the number of models available in the literature is limited. The complexity of the absorption of formaldehyde in water, in which chemical reactions in the liquid phase are combined with multicomponent mass transfer, makes the development of an adequate process model a challenging task. In this work, a rate-based model of an industrial absorption system for tray and packed columns was developed. The multicomponent mass transfer was described based on the two-film theory, and the model was implemented in the simulation tool gPROMS ModelBuilder 5.1.1 and validated against data from the design flowsheet provided by the industrial unit licensor and typical operation values measured in an industrial formaldehyde production unit. The simulation results were in good agreement with the expected data. With the validated model, the influence of some operating parameters on the column behavior was studied.
