“…Hence, to reduce the S-content into much lower limit (<50 ppm) is substantial task to produce clean sulfur free fuels (Babich and Moulijn 2003). Responsible editor: Santiago V. Luis In industry, traditional hydrodesulfurization (HDS) process is broadly used for EDS of liquid fuels where S-compounds react with H 2 and converted into H 2 S and hydrocarbons (Isao and Choi 2004;Tropsoe and Gate 1997;Ma et al 1994;Ferrari et al 2001;Dumeignil et al 2006;Dharaskar et al 2013a, b, c, d, a, b, c, d). HDS process is able to remove aliphatic thiols, sulfides, and disulfides effectively, whereas it is not as much competent for some thiophenic Scompounds like dibenzothiophene (DBT) and its derivatives (Pawelec et al 2001;Dharaskar et al 2014a, b, c).…”

1-Butyl-3-methylimidazolium thiocyanate [BMIM]SCN has been presented on extractive desulfurization of liquid fuel. The FTIR, (1)H-NMR, and C-NMR have been discussed for the molecular confirmation of synthesized [BMIM]SCN. Further, thermal, conductivity, moisture content, viscosity, and solubility analyses of [BMIM]SCN were carried out. The effects of time, temperature, sulfur compounds, ultrasonication, and recycling of [BMIM]SCN on removal of dibenzothiophene from liquid fuel were also investigated. In extractive desulfurization, removal of dibenzothiophene in n-dodecane was 86.5 % for mass ratio of 1:1 in 30 min at 30 °C under the mild process conditions. [BMIM]SCN could be reused five times without a significant decrease in activity. Also, in the desulfurization of real fuels, multistage extraction was examined. The data and results provided in the present paper explore the significant insights of imidazolium-based ionic liquids as novel extractant for extractive desulfurization of liquid fuels.

“…Imidazolium-based ILs were more soluble in water in comparison with phosphonium-based ILs [137]. Density was subjected to several factors, such as the size of the ring in the cation, the length of the alkyl chain in the cation, the symmetry of ions and the interaction forces between the cation and the anion [138].

“…In fact, solubility values up to 20 g/L have been observed for some imidazolium-based ILs [127]. Density was subjected to several factors, such as the size of the ring in the cation, the length of the alkyl chain in the cation, the symmetry of ions and the interaction forces between the cation and the anion [138]. Viscosity augmented as the alkyl group was increased for ILs with identical anion [139].…”

Summary Biobutanol has conventionally been generated by fermentation of carbohydrates derived from biomass (starch or sugar‐based feedstock, such as corn) using Clostridia strains (mainly C. beijerinckii and C. acetobutylicum) under anaerobic conditions in batch mode. Under these premises, it has been tough for the acetone–butanol–ethanol fermentation to compete with petro‐butanol production from an energy efficiency and material consumption standpoint. Challenges for butanol production from biomass comprised high cost of feedstock, scarcity of hyper‐butanol producing bacteria and low butanol yield, volumetric productivity and titre, leading to high water usage and separation‐purification costs. This article is an up‐to‐date review on several under explored sections, such as optimization of fermenter feed, microbial culture responsible for solvent production (co‐culture techniques and electro‐biochemical process), latest recovery techniques and the studies integrating in situ continuous fermentation processes. Biobutanol refinery way forward should build upon the use of low‐cost lignocellulosic matter and zero cost organic wastes and by‐products from food, agriculture, forestry, fermentation and paper industries as feedstock; optimized fermentation of such diversified feed with appropriate hyper‐butanol producing strains in biofilm reactors and integration of fermentation step with hybrid high butanol‐selective recovery techniques.

“…1-ethyl-3-methylimidazolium thiocyanate and dicyanamide exhibit the lowest electrochemical stabilities. When conductivity and thermal stability are both required in a separation or extraction process, imidazolium based ILs with stable anions e.g., tetrafluoroborate or hexafluorophosphate are applied [20].…”

A new class of energy efficient solvent, known as ionic liquids, has recently been the subject of demanding research on the extractive desulfurization of liquid fuels. The aim of this study is to investigate the possible application of ionic liquids as green energy efficient solvent because of their unique physical and chemical properties. In this work, Imidazolium based 1-butyl-3methyllimidazolium hexfluorophosphate [BMIM]PF6 and 1-butyl-3methyllimidazolium tetrafluoroborate [BMIM]BF4 were synthesized and employed as extractive agent for the removal of sulfur compounds. The effects of reaction time, reaction temperature, sulfur compounds, and recycling of ionic liquids without regeneration on dibenzothiphene removal of liquid fuel were presented. Also, the desulfurization of real fuels was investigated. The data and results of presented work might be provide significant insights of imidazoled ILs as green solvent for extractive desulfurization of liquid fuels as it can be reused to four cycle without regeneration with considerable extraction efficiency.
