Precursors diesel fuel

Table 41.3 shows a performance comparison of Pt/Pd TUD-1 with a commercial Pt/Pd catalyst (26). The feedstock is a typical straight run gasoil ( SRGO ), a distillate precursor to diesel fuel. Under identical test conditions, the TUD-1 catalyst achieved 75% aromatics saturation versus 50% for the same volume of commercial catalyst. This superior result is particularly interesting because the TUD-1 catalyst had a much lower density than the commercial material, so that less catalyst by weight was required in the reactor. 

Kerosene (kerosine) a fraction of petroleum that was initially sought as an illuminant in lamps a precursor to diesel fuel with a distillation range that generally falls within the limits of 150 and 300°C main uses are as a jet engine fuel, an illuminant, for heating purposes, and as a fuel for certain types of internal combustion engines. 

Many new sugar based products present the advantage of being non-toxic and biodegradable. The products resulting from the telomerization of 1 with appropriate nucleophiles such as alcohols, amines, water, or carbon dioxide serve generally as useful intermediates in the synthesis of various natural products and fine chemicals [60-63], as precursors for plasticizer alcohols [56, 64], components of diesel fuels [65], surfactants [11, 66], corrosions inhibitors, and non-volatile herbicides [67].

This will result in an increase in asphaltene agglomerations, polymerization and a dramatic loss of combustion efficiency. The chemistry of diesel fuel instability involves the chemical conversion of precursors to species of higher molecular weight with limited solubility. The conversion process often involves oxidation of the precursors. Fuel solvency plays a role, since the development of insolubles is always a function of both the presence of higher molecular weight species and the fuel s capacity to dissolve them. 

The next important parameter of diesel fuel is stability or storage stability. As fuel ages, it can become unstable and form insoluble particulates that accumulate and eventually end up on the fuel filter. For the most part, instability involves the chemical conversion of precursors to compounds of higher molecular weight with limited fuel solubility. The precursors are certain nitrogen and/or sulfur containing compounds, organic acids, and reactive olefins. The conversion process often involves oxidation of the precursors. Certain dissolved metals, especially...

Per mole of the starting fuel, the yield of molecular hydrogen (H2) is significantly preferred from a diesel precursor. 

Major sources of acidic precursors (SO2 and NO ) in Singapore include power stations, petroleum refineries, other industries and motor vehicles. Control of these pollutants isregulatedby the Clean Air Act of December 1971. Emissions ofS02 are controlled by restricting the sulfur content of automotive diesel and industrial fuel...
