“…These RD processes produce 100 kmol h −1 EL (equivalent to about 120 kt year −1 ) with a purity of 99.5 mol% (same as for water by‐product). This is consistent with the purity values reported in previous studies about the design of EL processes, and in the context of using EL as a fuel bio‐additive …”

BACKGROUND: Ethyl levulinate (EL) is an important chemical that can be used as a bio-based replacement of fuel additives such as methyl tert-butyl ether (MTBE) and tert-amyl methyl ether (TAME). EL production from lactic acid and ethanol is a viable option, as both precursors can be obtained from biomass. However, the problem of EL production by esterification is that this reaction is hindered by the chemical equilibrium limitations and the boiling points ranking, which is not the most favorable. RESULTS:This study provides novel optimally designed reactive distillation (RD) processes for the production of EL, taking into account costs, environmental impact and safety. The thermally coupled RD process is the most appealing, with the lowest energy use (1.667 MJ kg −1 EL), minimal investment cost, major energy savings (up to 54.3% lower than other RD processes), reduced environmental impact (up to 51% lower ECO99 index value) and similar safety as other RD processes considered (less than 2% differences in the individual risk (IR) indicator). CONCLUSION:The multi-objective optimization approach used here showed its robustness, practicality and flexibility to provide multiple optimal designs of intensified processes that are economically attractive, environmentally friendly and inherently safe. The first separation column (RC-1) performs the separation of water by-product as distillate from the main product (EL) and the unreacted LA. The second separation column (RC-2) wileyonlinelibrary.com/jctb Process optimizationThis study uses a multi-objective meta-heuristic optimization algorithm based on differential evolution and tabu list (MODE-TL), further details of which can be found elsewhere. 34 This algorithm allows the comparison of multiple solutions of optimized designs in the terms of multiple objective functions, described hereafter.

[34][35][36][37] Lei et al 38 have reported successful engine tests of various blends of ethyl levulinate and ethyl levulinate/n-butanol with a diesel fuel. Their measurement indicated that blends of fuel with higher concentrations of ethyl levulinate had lower heating value, lower close cup flash point, and lower cetane number as compared with those with lower concentrations.…”

Process design and techno‐economic analysis of ethyl levulinate production from carbon dioxide and 1,4‐butanediol as an alternative biofuel and fuel additive

Summary Carbon dioxide capture, utilization, and storage (CCUS) is one of the promising negative emission technologies (NET). Within various CCUS routes available, CO2 conversion into fuels is one of the attractive options. Currently, most of CO2 conversion into fuels requires hydrogen, which is expensive and consume large energy to produce. Hence, a different route of producing fuel from CO2 by utilizing 1,4‐butanediol as the raw material is proposed and evaluated in this study. This alternative route comprises production of levulinic acid from the reaction between CO2 and 1,4‐butanediol and production of ethyl levulinate, an alternative biofuel and biofuel additive, via an esterification reaction of levulinic acid with ethanol. The process is designed and simulated according to the available data and evaluated in terms of its technical features. Because of the unavailability of reaction data for synthesis of levulinic acid from 1,4‐butanediol and CO2, several assumptions were taken, which may implicate the accuracy of the studied design. This technical evaluation is followed by cost estimations and sensitivity analysis. Because of the free CO2, the profitability of the plant depends strongly on the prices of the other chemicals and the price difference between 1,4‐butanediol (raw material) and ethyl levulinate (product). Monte Carlo simulation indicates that the proposed plant will always be profitable if the ethyl levulinate is slightly more expensive than the 1,4‐butanediol, highlighting that the process of producing ethyl levulinate from CO2 is economically profitable. Future research should be directed towards a catalytic system that can effectively convert CO2 into levulinic acid, by‐products produced from the two reaction steps, and reduce the excess ethanol used in the second reaction.
