“…The variations in NOx emission versus engine load regarding different nanoparticle-diesel fuel blends are shown in Figure 19. As seen in this figure, the concentration of NOx in the exhaust gas of the engine increased at higher engine loads, which is related to the increase in combustion temperature at higher engine loads (Hojati 2019, Salehian 2020. Based on the findings, a significant reduction (20% on average) was observed in NOx emission following the addition of nanoparticles (especially Al2O3 nanoparticles) to neat fuel diesel.…”

This research investigates the effects of the addition of Fe2O3 and Al2O3 nanoparticles (30, 60, and 90 ppm) and Fe2O3-Al2O3 hybrid nanoparticles to pure diesel fuel on the combustion, performance and emission characteristics of a diesel engine. The results indicated that fuel blends improved the combustion (in-cylinder pressure and heat release rate), performance (power, fuel consumption, and thermal and exergy efficiency), and emission characteristics of the engine. The results showed that the peak combustion pressure increased by 4% and the heat release rate was improved by 15% in comparison with pure diesel with the addition of the nanoparticles. Moreover, the rate of pressure rise increased by 18% compared to pure diesel with nanoparticle additives. Based on the results, the effects of Fe2O3 fuel blends on brake power, BTE, and CO emission were more than Al2O3 fuel blends, such that it increased power and thermal efficiency by 7.40 and 14%, respectively, and reduced CO emissions by 21.2%; moreover, the blends with Al2O3 nanoparticle additives in comparison with Fe2O3 nanoparticle blends showed a better performance in reducing BSFC (9%), NOx (23.9%), and SO2 (23.4%) emissions. Overall, the Fe2O3-Al2O3 hybrid fuel blend is the best alternative if the performance and emission characteristics of the engine are both considered.

“…Several experts have done catalytic pyrolysis using alkaline catalysts, metal/zeolite catalysts, metal oxides, and microporous and mesoporous zeolites [27,28]. Catalytic pyrolysis using cordierite-platinum SCR has also been successfully employed by Salehian and Sirneshan [29] on diesel-ethanol fuel blends. During pyrolysis, a catalyst can signifcantly alter the reaction pathway [30].…”

“…Catalysts are used to improve the products of pyrolysis [9,32]. Te type of catalyst (acidic, alkaline, or metallic) and catalyst properties (acid site density, acid strength, and porosity) have a signifcant impact on product distribution and characteristics [1,5,29]. Te primary use of catalysts in tire pyrolysis is to reduce product distribution compared to noncatalytic thermal pyrolysis [5,31].…”

The large volume of tire waste generated globally poses a major waste disposal problem. In the natural environment, disposed of tires do not degrade easily, but they can be processed through pyrolysis, to get char, gas, and oil. In this study, tire pyrolysis was done using 0.00%, 1.50%, 2.50%, 5.00%, 7.50%, and 10.00% sodium carbonate catalyst in the feed material to produce oil. An evaluation of the effects of the catalyst on the cetane index, calorific value, pH level, and flash point of tire pyrolytic oil (TPO) was carried out since these are the essential properties in relation to safety in its handling and efficiency in engine performance and operation. There was a decrease in the calorific value by 3.09%, the flash point by 37.25%, and the cetane index by 71.2% with increasing catalyst percentage, while the pH was found to increase by 19.78% (between 0.00 and 5.00% sodium carbonate catalysts) and then decreased when more than 5.00% of the catalyst was employed. These results will provide theoretical information that will guide its handling and usage as fuel.

“…At various engine speeds, the exhaust gas from the engine that enters the catalyst was measured for various fuel blends. 17 The CI engine's performance, emissions, and combustion properties were examined using diesel and soybean as fuels. The findings demonstrated that biodiesel demonstrated an earlier start of combustion than soybean oil, which displayed similar combustion phases to those of diesel.…”
