Discovery of a High-Octane Environmental Gasoline Based on the Gasoline Fischer-Tropsch Process

摘要

Gasoline produced from Fischer-Tropsch technology has low detonation characteristics and does not have any aromatic hydrocarbons; thus, it should be maximized by blending with oxygenated compounds, which give good prospects for enhancing the physicochemical characteristics of them. This research investigates the production of an environmental gasoline with high quality depending upon gasoline produced from Fischer-Tropsch technology. An improvement in the octane rating of gasoline produced from Fischer-Tropsch technology was conducted by blending it with methanol and a blend of aromatic hydrocarbons of composition C-7-C-10, which includes toluene, o- and m-xylenes, and isopropyl benzene. Furthermore, physicochemical properties of gasoline produced were studied according to the standard regulations of Russian GOST 32513-2013, European EN 228:2012, Chinese GB 17930-2013, and Chinese for M30 fuel DB14/T614. The results showed that an environmentally produced gasoline, sample 3, has an octane rating by the research method (98.8) and the motor method (89) and corresponds to the "Super" gasoline brand. In addition, compositions meet the basic requirements for motor gasoline according to the previous standards. An induction period value of the produced gasoline is more than 480 min and also satisfies previous standard regulations. It is a good indicator that the produced gasoline does not form gum during the storage. Finally, the use of alternative motor gasoline allows for the decrease of the use of non-renewable mineral resources and a reduction of the negative impact on the environment when using it in internal combustion engines. Furthermore, the use of gasoline Fischer-Tropsch as a hydrocarbon base for alternative fuels can be considered as a potential promising option for producing an automobile gasoline.
