“…Due to the intricate, complex and rigid structure of lignocellulose, 145,146 generally, dissolution and separation of natural lignocellulose are performed by thermochemical and/or physical methods. 147 However, the conventional methods have limitations such as insufficient selectivity and partial degradation of the products. Recently, a lot of effort has been focused on understanding the pathways to improve the selective separation of lignocellulose to accomplish feasible and sustainable processes based on ILs.…”

To mitigate the growing pressure on resource depletion and environment degradation, the development of green processes for the production of renewable energy is highly required. As a class of novel and promising media, ionic liquids (ILs) have shown infusive potential applications in energy production. Aiming to offer a critical overview regarding the new challenges and opportunities of ILs for developing green processes of renewable energy, this article emphasises the role of ILs as catalysts, solvents, or electrolytes in three broadly interesting energy production processes from renewable resources, such as CO2 conversion to fuels and fuel additives, biomass pretreatment and conversion to biofuels, as well as solar energy and energy storage. It is expected that this article will stimulate a generation of new ideas and new technologies in IL-based renewable energy production.

“…New and efficient solvents are required to help unlock the promise of keratin dissolution, and in this regard, the eld of ILs might actually live up to its tremendous potential. 7,17 As a new class of designer solvents, ILs can dissolve a large number of biopolymers, such as, feathers, 10,18,19 cellulose, [20][21][22][23] wool, 2,24,25 chitosan, 26,27 lignin, 28 and silk, 29,30 with high efficiency, due to their unique properties such as high thermal stability, tunable properties, and good dissolving ability. 8 Promising results for the dissolution of keratin in ILs have also been obtained.…”

“…However, concepts such as hydrogen bonding may not be sufficient to understand and predict interactions between ILs and lignocellulose, for which there are many other factors that require consideration. 55 The COSMO-RS model has been shown to be very useful for screening ILs for lignocellulose treatment 1,56 as only structural information is typically required for the prediction of solubility and other thermodynamic properties. Being able to screen ILs through the use of predictive methods requiring a minimal amount of input properties would allow for much-needed savings in time, cost and effort in laboratory studies.…”

HOW TO CITE:Reddy P. A critical review of ionic liquids for the pretreatment of lignocellulosic biomass. S Afr J Sci. 2015;111(11/12), Art. #2015-0083, 9 pages. http://dx.doi.org/10. 17159/ sajs.2015/20150083 Ionic liquids have been the subject of active research over the course of the last decade and have in the past been touted as one of the most promising technologies for revolutionising the chemical and petrochemical industries. The sheer abundance of potential ionic liquid structures coupled with their tuneable physico-chemical properties has endeared ionic liquids to the scientific community across a broad range of disciplines with potential applications that include pharmaceuticals, electrolytes, thermal energy storage media and liquid mirror telescopes. Within the context of a biorefinery for the production of biofuels and other bio-based products from renewable resources, the unique abilities of some ionic liquids to selectively dissolve biomass components or whole native biomass have been demonstrated. This ability has sparked extensive investigations of ionic liquids for the pretreatment of different biomass types, particularly for the production of cellulosic biofuels. However, the esoteric nature of ionic liquids persists and constructing a fundamental framework for correlating ionic liquid structures with useful applications remains a significant challenge. In addition to the above, the more practical challenges of toxicity, high costs, high viscosities, low solids loading and complex recycling are key factors hindering the wide-scale uptake of ionic liquids as pretreatment solvents in a commercial biorefinery. This critical review provides insights from academic studies and the implications thereof for elevating ionic liquids from the status of 'promising' to 'commercialisable' in the pretreatment of biomass. It is vital that key hurdles for the commercialisation of ionic liquids in the form of high costs, high viscosities, poor water tolerance, toxicity, low solids loading and recovery/recycling be addressed.
