“…With the rapid depletion of fossil fuels, biofuels have been recognized as one of the most potential alternative energy sources. − As a typical class of biofuels, alcohols have aroused increasing interest in recent years. Alcohols have been widely used as alternative fuels or fuel additives, because they can effectively inhibit the formation of polyaromatic hydrocarbons (PAHs) and soot in combustion processes. − As we know, bioethanol has already been blended with gasoline for use in combustion internal engines and biobutanol has even been directly used without blending. , Although large amounts of investigations have been carried out on monohydric alcohols (such as methanol, ethanol, propanol and butanol), − polyols gained less attention.…”

The unimolecular decomposition processes of ethylene glycol have been investigated with the QCISD(T) method with geometries optimized at the B3LYP/6-311++G(d,p) level. Among the decomposition channels identified, the H(2)O-elimination channels have the lowest barriers, and the C-C bond dissociation is the lowest-energy dissociation channel among the barrierless reactions (the direct bond cleavage reactions). The temperature and pressure dependent rate constant calculations show that the H(2)O-elimination reactions are predominant at low temperature, whereas at high temperature, the direct C-C bond dissociation reaction is dominant. At 1 atm, in the temperature range 500-2000 K, the calculated rate constant is expressed to be 7.63 × 10(47)T(-10.38) exp(-42262/T) for the channel CH(2)OHCH(2)OH → CH(2)CHOH + H(2)O, and 2.48 × 10(51)T(-11.58) exp(-43593/T) for the channel CH(2)OHCH(2)OH → CH(3)CHO + H(2)O, whereas for the direct bond dissociation reaction CH(2)OHCH(2)OH → CH(2)OH + CH(2)OH the rate constant expression is 1.04 × 10(71)T(-16.16) exp(-52414/T).

“…Biofuels such as bioethanol and biodiesel were found to be among the most promising and attractive solutions to the replacement of fossil fuels in the transportation sector. 40 First generation biofuels are primarily derived from crop plant products such as sugar and starch for ethanol while vegetable oils and animal fats for biodiesel production. 41,42 The major plants investigated and utilized were sugar cane, corn and wheat for ethanol while palm oil, sunflower seeds, castor seeds, rapeseed and soybean for biodiesel among many others.…”

It is expected that 84% of the global energy demands will be met through fossil fuels in 2030 due to increasing energy needs. However, due to their impact on the environment through the emission of anthropogenic green house gases, biofuels were introduced as alternative sources of energy. Biofuels of plant origin for the transport sector proved to be controversial due to competition for food production, fertile land and expensive production processes. As a secondary alternative, microalgae such as Scenedesmus obliquus, Chlorella vulgaris and Nannochloropsis sp. were found to be suitable candidates for liquid biofuels production. This review describes the production of transportation liquid biofuels from plant biomass and microalgae. Information is provided on how the controversies related to plant biomass lead to the use of algal biomass. The production processes involved in both generations are discussed and highlighted. Furthermore, details on the production of secondary products such as pigments, feed additives and valuable secondary metabolites are also provided.

“…Bioethanol, obtained through fermentation of biomass sources, including sugarcane and corn, exhibits low pollutant emissions and can potentially replace conventional fuels derived from oil and natural gas [ 1 ]. For instance, bioethanol is popular in Brazil due to its cost-effectiveness and reduced environmental impact when used in automotive engines [ 2 , 3 ]. In 2022, more than 590 million tons of sugarcane were processed to produce 58 billion liters of bioethanol [ 4 , 5 ].…”

A miniaturized and low-cost electrochemical 3D-printed system for rapid and accurate quantification of ethanol content in ethanol fuel using electrochemical impedance spectroscopy (EIS) was developed. The monolithic design of the system incorporates insulating thermoplastic electrode separators, with only the cover being mobile, allowing for easy assembly and handling. The portable device, measuring approximately 26 × 24 mm, has a maximum capacity of 1 mL, making it suitable for lab-on-a-chip and portable analysis. By utilizing the dielectric constant of ethanol and ethanol fuel mixtures with water, the miniaturized EIS cell quantifies ethanol content effectively. To validate its performance, we compared measurements from four gas stations with a digital densimeter, and the values obtained from the proposed system matched perfectly. Our miniaturized and low-cost electrochemical 3D-printed device can be printed and assembled in two hours, offering a cost-effective solution for fast and precise ethanol quantification. Its versatility, affordability, and compatibility with lab-on-a-chip platforms make it easily applicable, including for fuel quality control and on-site analysis in remote locations.
