Research on high cetane and high octane number fuels and the mechanism for their common oxidation and auto-ignition

A hybrid statistical approach for modeling and optimization of RON: A comparative study and combined application of response surface methodology (RSM) and artificial neural network (ANN) based on design of experiment (DOE)

“…This can be attributed to the fact that raising the reaction temperature at low operating pressure, thermodynamically favored the aromatization activity as well as the formation of Olefin hydrocarbons. However, these hydrocarbons have high octane numbers that tend to enhance the RON of reformat [39][40][41]. This confirms the results obtained from Pareto chart shown in Table 4 which implies that the reaction temperature parameter is the most influential variable on RON in the catalytic naphtha reforming process.…”

Current trends on combustion control methods using fuel reactivities

“…Low reactive fuel is being port injected which generally has high octane number to bear the engine compression ratio in order to reduce knock [53]. It was reported that gasoline has high octane number-100 [57] and it can be used as low reactive fuel. However, it can also be utilised as high reactive fuel with the use of cetane enhancer (Di Tertiary Butyl Peroxide or Ethyl Hexyl Nitrate) [58][59][60].…”

“…It was reported that fuels with CN < 30 are said to be below reactive and fuels with CN > 60 are said to be high reactive [76]. Fuels with high cetane number has straight chain alkanes, straight chain ethers and long straight chain esters, making it highly reactive [57]. Hence, it has been suggested to use high cetane number fuel as HRF and low cetane number fuel as LRF.…”

Platinum‐promoted fibrous silica Y zeolite with enhanced mass transfer as a highly selective catalyst for n ‐dodecane hydroisomerization

“…This is basically due to increasingly stringent environmental protection regulations with regards to the use of aromatics and olefins in gasoline for octane number enhancement. Additionally, production of high cetane diesel fuel and improved cold flow properties, such as freezing point, pour point, and viscosity, requires an efficient catalyst to facilitate hydroisomerization of C 7 –C 15 n‐ paraffins …”

“…[6][7][8] This is basically due to increasingly stringent environmental protection regulations with regards to the use of aromatics and olefins in gasoline for octane number enhancement. Additionally, production of high cetane diesel fuel 9 and improved cold flow properties, such as freezing point, pour point, and viscosity, requires an efficient catalyst to facilitate hydroisomerization of C 7 -C 15 n-paraffins. 10 Generally, hydroisomerization of n-alkanes is usually accompanied by a competing hydrocracking reaction especially when higher molecular weight n-paraffins are involved as reactants.…”
