Special Issue Information

Dear Colleagues,

Nowadays, decreasing carbon-emission has become the global theme. Therefore, in order to achieve the carbon neutrality in the middle of this century, many efforts should be done for the low- and zero- combustion applied in vehicles, marines, gas turbines and even aircraft engines. As we known, fuel spray and combustion have significant effects on the efficiency and emission. And much more investigations should be done to develop new models and strategies for low-carbon engines. Besides, in the recent decades, e-fuel become popular and could be obtained successfully by the help of solar and wind energies. In such a case, the sustainable fuels could continue to survive in the future. Therefore, the special issue from Sustainability is organized and named as “Sustainable Fuel Spray, Fuel Film Formation and Combustion Applied in Low-carbon Powertrains”. Now, we are encouraging all the scholars to contribute to it and report your good ideas and achievements. We believe it would be a great issue and provide excellent coverage of the current technology.

Potential topics include but are not limited to: Liquid spray and impingement; E-fuel characteristics; Fuel film formation; Low-carbon combustion; Development of zero and low carbon fuels; Model development in spray and combustion.

Low-carbon powertrains and sustainable fuels are closely linked as they both aim to reduce carbon emissions and transition away from reliance on fossil fuels. The methane from biogas, biomass, and organic waste can serve as an alternative energy source to traditional fossil fuels. The process of obtaining sustainable fuel (e.g., hydrogen and syngas) from methane is commonly confronted with the problems of carbon deposition on metal oxide. The study of carbon deposition characteristics during methane thermal conversion processes is particularly crucial for low-carbon powertrains. Herein, the carbon deposition on CoAl2O4 and strongly alkali-etched CoAl2O4 (CoAlvO4) spinel oxides from the CH4 stage was investigated. We demonstrate that reaction time, calcination temperature, and reaction temperature have no effect on the compositions of carbon deposition, and the material itself plays a crucial role in carbon deposition. The graphitization degree for CoAlvO4 is lower than that for CoAl2O4. The strong alkali etching in CoAl2O4 only affects contents in different composition carbon deposition. This is mainly attributed to the introduction of Al3+ vacancies by alkali etching, which efficiently tunes the surface electronic structure in CoAl2O4. These findings guide designing efficient and clean low-carbon powertrains, especially in the development of removal carbon deposition technologies and catalysts. Full article
