“…However, even if the antiknock index of ML is high, its full miscibility with water and separation from gasoline at cold temperatures makes practically disadvantageous its use for this purpose [47]. Additionally, in the field of diesel fuels, the use of EL as bio-based cold-flow improvers in bio-diesel fuels has been demonstrated [47,175], but hindered by miscibility issues [176]. In order to further increase the AL miscibility in diesel fuels, the attention isnow moving rather towards higher molecular-weight alcohols.…”

Alkyl levulinates (ALs) represent outstanding bio-fuels and strategic bio-products within the context of the marketing of levulinic acid derivatives. However, their synthesis by acid-catalyzed esterification of pure levulinic acid, or by acid-catalyzed alcoholysis of furfuryl alcohol, although relatively simple, is still economically disadvantageous, due to the high costs of the pure precursors. The direct one-pot alcoholysis of model C6 carbohydrates and raw biomass represents an alternative approach for the one-step synthesis of ALs. In order to promote the market for these bio-products and, concurrently, the immediate development of new applications, it is necessary to speed up the intensification of their production processes, and this important achievement is onlypossible by using low-cost or, even better, waste biomasses, as starting feedstocks. This review provides an overview of the most recent and promising advances on the one-pot production of ALs from model C6 carbohydrates and real biomasses, in the presence of homogeneous or heterogeneous acid catalysts. The use of model C6 carbohydrates allows for the identification of the best obtainable ALs yields, resulting in being strategic for the development of new smart catalysts, whose chemical properties must be properly tuned, taking into account the involved reaction mechanism. On the other hand, the transition to the real biomass now represents a necessary choice for allowing the next ALs production on a larger scale. The improvement of the available synthetic strategies, the use of raw materials and the development of new applications for ALs will contribute to develop more intensified, greener, and sustainable processes.

Many engine specialists have utilized various oxygenated blends such as methyl and ethyl esters, alcoholic fuels, and ether to boost the efficiency of dual fuel engine (DFE). However, there hasn’t been much study done to examine the effects of di-ethyl ether (DEE) in a gaseous fueled engine. Hence, in the present study, the author has examined the impact of the DEE/diesel mixture on the combustion, performance, and exhaust emissions in the acetylene-fueled customized engine. The acetylene is injected at 4 l/min (LPM) through the intake manifold while neat diesel, BD05, BD10, BD15, and BD20 blends are used as ignition sources at various engine loads. It is found that when the engine is operated with an ABD10 fuel combination the brake thermal efficiency (BTE) inclines by 1.7% as compared to standard diesel. The BTE is escalated due to an increased DEE proportion of up to 10% using BD10 pilot fuel at 80% load. However, further increasing the proportion of DEE results is a bit inferior in comparison to conventional diesel mode. Moreover, HC, CO, NOx, and smoke reduce considerably by 27%, 45%, 22%, and 43% respectively in comparison to neat diesel at 80% load while utilizing ABD10 fuel. This may be attributed to the superior physico-chemical properties of the pilot fuel blends permitting legitimate burning of the acetylene-air mixture. Additionally, it is also observed that consumption of neat diesel is decreased by 40% under high load using BD10 mixture as pilot fuel. Consequently, it is recommended to use DEE up to 10% with standard diesel in an acetylene-fueled engine for increasing BTE as well as to mitigate exhaust pollutants.
