“…[35][36][37] The process with a lower conditional number (or a higher minimum singular values) [Eqn (3)] generally signifies better dynamic characteristics under disturbance. 13,38 In this work, ⊞ max and ⊞ min are calculated with the MATLAB program using the temperature difference obtained from the sensitivity analysis (see Section 3.3).…”

Background Here we analysed the possibility of improving the sustainability performance for the recovery of dichloromethane and methanol from a binary azeotropic mixture using different energy‐intensified extractive distillation‐based processes: side‐stream extractive distillation (SSED), thermally coupled extractive distillation (TCED), and extractive dividing wall column (EDWC). The sustainability performance of the different processes was analysed based on three main factors: total annual cost (TAC), CO2 emissions, and condition number. Results The EDWC was found to give the best improvement in terms of TAC and CO2 emissions by about 18% and 21%, relative to conventional extractive distillation (CED). These however were traded‐off by the increase in conditional number (CN) by 186 times, signifying a complex dynamic characteristic for the EDWC. Thus, the SSED was suggested as an alternative sustainable option as it also provides significant improvement in TAC and CO2 emissions by about 11%, and 18% with respect to the CED, whilst providing the least reduction in operational controllability, as evidenced by the marginal increase in the CN of about 1.5 times. We also investigated the dynamic performance of the SSED and found that the SSED provides identical dynamic performance in handling both ±10% throughput and ±5% feed composition disturbances as those of the CED. Conclusion Among the different processes, SSED is the best sustainable alternative that provides compromised steady‐state (i.e. TAC and CO2 emissions) and dynamic (i.e. control) performance for the recovery of dichloromethane and methanol. © 2022 Society of Chemical Industry (SCI).

“…19,23 Different approaches for an efficient purification of 2,3-BD from a fermentation medium, such as distillation, pervaporation, solvent extraction, and reverse osmosis, have been analyzed. 24,25 Lately, even more complex processes, such as anionic extraction based on the formation of reversible complexes, 26 extraction and subsequent purification with ionic-liquids, 27 or liquid−liquid extraction coupled with a thermal approach, 28 were analyzed and further optimized to increase the efficiency. 29 In the process models, the environmental impact of the separation could be decreased 14%.…”

2-Butanone, commonly known as methyl ethyl ketone (MEK), is a widely used solvent in the chemical industry, which is usually produced by reducing petrochemically derived 2butanol. This work develops a sustainable production process for 2butanone from renewable resources. The process includes the biotechnological conversion of biomass to acetoin and the subsequent electrochemical reduction to 2-butanone. Direct electrocatalytic reduction of acetoin in a fermentation supernatant without prior purification mitigates process complexity and increases the process efficiency of the electrochemical production route. We show that production of 2-butanone from a fermentation broth is feasible with a slightly decreased yield compared to model solution experiments. Further, constant current experiments reveal a yield and selectivity dependence of the fermentation broth pH, which is not apparent in the model solution. Starting from 50 g L −1 acetoin fermentation broth, we reach approximately 50% yield of 2-butanone with a product selectivity of 80%. The conversion of acetoin is limited due to side product formation and the hydrogen evolution reaction. This work contributes to the development of solvents based on sustainable resources and processes.

“…26 Due to the worldwide interest in diversifying clean energy sources other than oil derivatives, such as methyl ethyl ketone (MEK), which has recently been characterized by a high-octane number and as a next-generation biofuel candidate for use in spark-ignition engines. [27][28][29] It can be biotechnologically synthesized from biomass or 2,3butanediol, 30,31 by hydrogenation of 2,3-butanediol 32 and through dehydrogenation of 2-butanol (2B). 33,34 For all of these reasons, we have strongly encouraged the development of highly basic modified solid-catalyst, such as ZnO modified with 1%-10% K 2 O, and to examine these potent catalysts during the production of MEK at a relatively low temperature with higher selectivity.…”

Herein we demonstrate the preparation and characterization of nanocrystalline ZnO, either pure or promoted with 1–10 wt.% K2O. All catalysts calcined at 400°C were in the nano‐crystallite scale as confirmed by X‐ray powder diffraction analysis in the 22.9–28.0 nm range. According to the CO2‐temperature‐programmed desorption study using thermogravimetric analysis and differential scanning calorimetry techniques, they have a broad spectrum of surface basic sites. Because of the significance of methyl ethyl ketone (MEK) as a next‐generation biofuel candidate with high‐octane, low boiling point, and relatively high vapor pressure. The prepared catalysts were examined during the direct production of MEK via 2‐butanol (2B) dehydrogenation. Among catalysts tested, ZnO promoted with 1% K2O showed a superior catalytic activity towards the conversion of 2B to MEK, that is, 71.7% at a reaction temperature of 275°C. The selectivity for the production of MEK over all catalysts was ≥95% across all catalysts when using N2‐gas as a carrier. The use of airflow in this reaction resulted in a clear loss of selectivity toward MEK production as well as the appearance of undesirable products such as acetone and methanol. All catalytic properties of catalysts, particularly those of moderate strength, were highly correlated with the distribution of surface basic sites. Finally, a reaction mechanism was proposed for the dehydrogenation of 2B, followed by the partial oxidation of MEK.
