“…It depends upon the boiling point range of gasoline octane enhancers, and they expect the action of the motor fuel from the injection manner to combustion. The composition of the fractions affects how easy it will be to start the engine, the time it takes to warm up, and throttle response . The introduction of MEIH to motor gasoline is considerably influenced by the boiling point of the blend.…”

High concentrations of isoolefinic hydrocarbons can adversely affect the physical, chemical, mechanical, and ecological characteristics of gasoline fuels. One of the solutions to reduce olefin contents is the utilization of the methoxylation process. The current paper declares a perspective toward a gasoline-component-first technique, revealing an innovative highoctane additive on the basis of isoolefinic components, like isohexene. The olefin content of isohexene was 94% volumetrically. This affected the chemical oxidation under atmospheric conditions. Several gasoline fuels and experimental facilities that match European and Russian requirements were used to execute the recent work. The objective of the methoxylation process is to enhance the chemical oxidation fuels to raise the portion of aliphatic hydrocarbon isomers, to decrease unwanted olefin content, as well as to generate high-octane motor ethers as gasoline octane boosters. The product can be defined as methyl ester of isohexene (MEIH). Various MEIH blends have been measured with other gasoline octane boosters and refinery products. The results proved that antidetonation properties of MEIH were higher than those of base gasolines, tertiary amyl methyl ether (TAME), and isohexene and approximately equal to that of methyl tertiary butyl ether (MTBE). Additionally, the results of the calculated MEIH mixing octane rating were from 104.3 to 131.5 for the research method and from 87.5 to 120.0 for the motor method. Likewise, the olefin content of MEIH was 74.2% when the methoxylation process was applied for isohexene. The oxygen content of MEIH was 3.3 wt %, with no oxygen content in the sample of isohexene. Those have been done thanks to the utilization of the methoxylation process of isohexene. Finally, MEIH provided an individual perspective as a liquid transportation fuel with merits over isohexene, in terms of antidetonation properties, olefin contents, as well as a distillation characteristic range.

“…As a clean energy carrier, ethanol is the most widely utilized non‐fossil fuel for transportation globally. [ 29,30 ] These results may also be valuable for researchers working to improve the microbial production of ethanol. Additionally, the formate and acetate titers of WT‐Δ ldh /ryhB were both higher than that of WT at all oxygen supply levels tested in this study.…”

Background Biogenic 2,3‐butanediol (2,3‐BDO) is a high‐value‐added compound that can be used as a liquid fuel and a platform chemical. Bioproduction of 2,3‐BDO is an environmentally friendly choice. Method and Results Three recombinant derivatives of the novel Klebsiella sp. isolate FSoil 024 (WT) were constructed via different strategies including deletion of lactate dehydrogenase by λ‐Red homologous recombination technology, overexpression of the small‐noncoding RNA RyhB and a combination of both. The 2,3‐BDO productivity of the mutants increased by 61.3%–79%, and WT‐Δldh/ryhB displayed the highest 2,3‐BDO yield of 42.36 mM after 24 h of shake‐flask fermentation. Glucose was shown as the best carbon source for 2,3‐BDO production by WT‐Δldh/ryhB. In addition, higher oxygenation was favorable for ideal product synthesis. The maximal 2,3‐BDO yield of WT and WT‐Δldh/ryhB were increased by 23.3% and 52.5% respectively compared to the control group in the presence of 70% oxygen (V:V’ = O2:(O2 + N2)). Conclusion and Implications According to the present study, deletion of lactate dehydrogenase, RyhB overexpression, and manipulation of oxygen supply showed great impacts on cell growth, 2,3‐BDO productivity and cellular metabolism of the novel isolated strain Klebsiella sp. FSoil 024. This work would also provide insights for promoting 2,3‐BDO biosynthesis for industrial applications.

“…The higher concentrations of bioethanol are used in flexible fuel vehicles (FFV) that can function with the mixtures up to 85% bioethanol [ 92 ]. Bioethanol is converted into ethyl tertiary butyl ether that can be used as a 15% blend with gasoline [ 93 ]. The potential bioethanol production is an important bioprocess in the industrial sector.…”

Graphic abstract The rapid industrial and economic development runs on fossil fuel and other energy sources. Limited oil reserves, environmental issues, and high transportation costs lead towards carbon unbiased renewable and sustainable fuel. Compared to other carbon-based fuels, biodiesel is attracted worldwide as a biofuel for the reduction of global dependence on fossil fuels and the greenhouse effect. During biodiesel production, approximately 10% of glycerol is formed in the transesterification process in a biodiesel plant. The ditching of crude glycerol is important as it contains salt, free fatty acids, and methanol that cause contamination of soil and creates environmental challenges for researchers. However, the excessive cost of crude glycerol refining and market capacity encourage the biodiesel industries for developing a new idea for utilising and produced extra sources of income and treat biodiesel waste. This review focuses on the significance of crude glycerol in the value-added utilisation and conversion to bioethanol by a fermentation process and describes the opportunities of glycerol in various applications.
