Making Levulinic Acid and Ethyl Levulinate Economically Viable: A Worldwide Technoeconomic and Environmental Assessment of Possible Routes

et al. 2017

View full text Add to dashboard Cite

Ethyl levulinate is a diesel additive that has received special attention recently due to its potential for production in large quantities from inexpensive feedstocks. Several processes have been developed for the conversion of biomass into levulinic acid and ethyl levulinate, and an economic analysis of these routes would indicate the main hindering factors of their commercialization. This Review focuses on filling this gap in current knowledge by gathering data from scientific papers and patents to create a simulation to analyze processes by focusing on the production of ethyl levulinate in nine countries or regions across the globe. The key indicator to analyze the economic feasibility of ethyl levulinate production is a comparison of its minimum selling price to the local wholesale price of diesel on an energy basis. Processes simulated in Brazil, China, and India presented promising results with feedstocks such as sugarcane bagasse and rice residues. Also, the integration of ethyl levulinate production into existing ethanol plants is a factor that may improve process economics. Overall, this Review specifies key factors in economic and environmental performances of the processes to indicate research topics that could achieve high impact on industrial‐scale processes once matured.

“…shows the TG and DTG curves of the three samples at the heating rate of 20°C/min. Both TG curves showed three steps of weight loss at elevated temperature formed by the evaporation of water and light volatiles, the decomposition of carbohydrates, and the decomposition of lignin, respectively[50]. The steep weight loss between 260 and 400°C shown in the TG curves indicated the degradation of main components in the samples.…”

In this study, the influence of ultrasound-assisted extraction on eucalyptus samples with special focus on pyrolysis characteristics and kinetic parameters was explored. Ultrasound and Soxhlet extraction were used to pretreat samples respectively, then samples were assayed by component analysis, TG-FTIR, and kinetic analysis. Ultrasound-assisted extraction did change the physiochemical characteristics of eucalyptus samples, particularly in regards to the quantity of extractives obtained. In TG and DTG curves, ultrasound-extracted samples reflected lower residual weight ratio (17.77%) and higher maximum weight loss rate (-22.92%/min), and were accompanied by a slight shift in the weight loss rate peak to lower temperature (366°C). The volatiles produced during pyrolysis and the discrepancies of product distribution between experimental and controlled groups were explored based on TG-FTIR spectra. According to kinetic analysis results, ultrasound-treated samples showed higher activation energy at the primary portion of thermal degradation with an average of 206.09kJ/mol.

“… found a similar nature of the curves with poplar sawdust. This is because the time required to reach the same reaction temperature will be shortened and there is no sufficient residence time for the volatiles evolving at that reaction temperature, hence higher temperature is required for the decomposition process . The maximum devolatilization peak in the DTG curve shifted from 612.9 K at 5 K/min to 637.9 K at 20 K/min without any change in its nature.…”

Thermochemical conversion of biomass for bio‐energy production is a potential option where condensable fractions can be utilized as fuel or for valuable chemicals and residual fractions for syngas (CO + H2) production. Present study aims at investigating the physicochemical properties and pyrolysis kinetics of Indian sagwan sawdust degradation using thermogravimetric analyzer at three heating rates (5, 10, and 20 K/min). Physical and chemical properties of ISS were determined by proximate, ultimate, compositional analysis, FTIR, XRD, and higher heating value. TGA results showed maximum devolatilization took place in the temperature range of 480–750 K. Three different iso‐conversional models Flynn–Wall–Ozawa, Kissinger–Akahira–Sunose, and Friedman methods were applied on TGA results to calculate the activation energy and pre‐exponential factors. Average activation energies from FWO, KAS, and Friedman methods were 145.78, 143.35, and 142.87 kJ/mol and pre‐exponential factors ranged from 105 to 1011 indicating empirical first order reaction. Gibbs free energy change and entropy change varied from 184.43 to 187.21 kJ/mol and from −147.21 to −35.59 J/mol, representing disorderness of products were lower than that of the initial compound. The above kinetics, thermodynamics and HHV results, confirmed that ISS has enough potential to be a source bio‐energy. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13131, 2019
