Definitions
- the present invention relates to a method for hydrotreating a paraffinic synthetic fuel produced by the reaction of carbon monoxide with hydrogen, so-called Fischer-Tropsch (FT) synthesis.
- FT Fischer-Tropsch
- Kerosene oil distillate derived from crude oil generally contains sulfur compounds, and when these oils are used as diesel vehicle fuel, the sulfur present in sulfur compounds has a low molecular weight. It is converted into sulfur compounds and discharged into the atmosphere. In addition, in exhaust gas aftertreatment devices that have been introduced in recent years, if sulfur compounds are present in the fuel, the catalyst used may be poisoned. In addition, there are many reports that crude oil-derived kerosene distillate contains aromatics, has a high aromatic content, and increases particulate matter (PM) and nitrogen oxides (NOx). Therefore, it is desirable for diesel vehicle fuels to have low sulfur and aromatic content.
- PM particulate matter
- NOx nitrogen oxides
- synthetic hydrocarbon oil produced by Fischer-Tropsch synthesis (hereinafter also referred to as FT method) using carbon monoxide and synthesis gas that is hydrogen power removes impurities in the synthesis gas. Therefore, sulfur compounds are not included. Moreover, since norafine is the main component, it contains almost no aromatics. Therefore, it can be said that the synthetic hydrocarbon oil obtained by the FT method is a suitable fuel for diesel vehicles.
- the synthetic fuel produced by the FT method contains some force olefins and oxygen-containing compounds whose main components are normal paraffins. These substances are generally not included in kerosene distillates derived from crude oil. If olefins are contained in a large amount in automobile fuel, peroxides may form and clogging may occur in fuel filters. In addition, if a small amount of oxygen-containing compound is contained, it will cause corrosion of the fuel tank and the fuel supply system. Therefore, in order to use the synthetic hydrocarbon oil produced by the FT method as an automobile fuel, it is necessary to remove olefins and oxygen-containing compounds.
