“…The worldwide demand for transport energy is large and is growing every year despite of development in electric vehicles (Liu et al 2022;Lebrouhi et al 2021;Chia et al 2022). Diesel engines offer numerous advantages over other power plants and are prevalent in the industrial, agricultural, heavy-duty transport sectors and commercial establishments (Sharma et al 2022;Reddy et al 2018;Hoang 2021).…”

Combustion of fossil fuel produces emissions and is one of the major environmental problems leading to climate change. Diesel engines are highly efficient but produce particulate emissions. These particulate emissions are considered dangerous to human health because inhaling particulates may cause respiratory and heart disease. Substituting fossil diesel fuel with renewable diesel fuel and using diesel particulate filters is one possibility to meet stringent legislative requirements. With this motivation, the present experimental investigation aimed to evaluate the particle size distribution (PSD), optical properties of particulate matter (PM) emitted, and the outcome of using an after-treatment system comprising of a diesel particle filter (DPF). This investigation aimed to make a comparative analysis of particulate emission upstream and downstream of the DPF with and without ultraviolet (UV) light (405 nm and 781 nm wavelength) turned on/off. Experiments were performed at (a) engine idle with a torque of 6 Nm at 750 rpm, IMEP of 1.35 bar and power of 0.5 kW, (b) engine at part load with a torque of 32 Nm at 1200 rpm, IMEP of 8.5 bar and power of 4.5 kW. Diesel engine was operated on two fuels (a) Diesel and (b) EHR7. Results showed that as and when UV light was turned on, a distinct nucleation mode that dominated the number concentration for both test fuels were observed. Downstream of the filter had relatively higher AAE values which show the contribution to climate change. Present experimental research is important for renewable fuel industries, industrial innovation's future, and the exhaust gas after-treatment system (EATS) community. The results contribute to knowledge for occupational exposure, human health, and the environment.

“…Extensive consumption of fossil fuel has aggravated the issue of environmental pollution, and it is urgent to explore clean and renewable energy sources to satisfy the increasing requirement of society and for economic development. 1 Hydrogen is a promising energy source because of its attractive features such as no CO 2 emission and high energy density. 2 At present, ∼95% of hydrogen is obtained by reforming fossil fuels; however, it is not a sustainable and eco-friendly method due to the emission of CO 2 and hazardous gases.…”

“…The utilization of renewable biomass as raw materials for production of transport fuels and value-added chemicals can reduce the overdependence on fossil resources and promote the realization of carbon neutrality as well as an ecological circular economy. − Lignocellulose, constructed by cellulose, hemicellulose, and lignin, represents one of the most promising sustainable sources of raw carbon material, which is readily available in the form of nonedible agricultural and forestry waste. − The development of an efficient strategy to transform lignocellulose into fuels and valuable chemicals has attracted considerable attention over the past decade, resulting in various versatile biobased molecules (i.e., 5-hydroxymethylfurfural, furfural, levulinic acid, lactic acid, γ-valerolactone, and cyclopentanone) easily accessible from lignocellulose, − which serve as an important bridge to produce end products such as fuels and fine chemicals. − …”

Acetalization is a promising method for upgrading biomass-derived molecules into valuable chemicals, and acetal products are considered excellent oxygenated fuel additives. Herein, a catalyst-free, facile, and effective protocol for the acetalization of furfural and ethylene glycol is established, affording a 78.6% yield of 2-(furan-2-yl)-1,3-dioxolane with a furfural/ ethylene glycol molar ratio of 1:15 in cyclohexane at 160 °C after 2 h. Moreover, the lower activation energy (15.8 kJ/mol) corroborates that the established system is efficient, and the thermodynamic studies demonstrate that catalyst-free acetalization is an endothermic, nonspontaneous, and endergonic reaction. A plausible mechanism including two pathways for catalyst-free acetalization of furfural and ethylene glycol is proposed, wherein the formed water from the acetalization process can render the ethylene glycol to be hydrolyzed, which plays a positive role in facilitating the acetalization of furfural and ethylene glycol. In addition, the excess ethylene glycol in the reaction mixture can be easily recovered and almost shows the same activity as fresh ethylene glycol in catalyst-free acetalization. Furthermore, the established catalyst-free protocol is viable for various biobased furanic compounds and alcohols, enabling broad access to various acetals. Finally, catalyst-free acetalization of furfural and ethylene glycol can be magnified to 10 times, showing the promising potential of large-scale production.
