  1. 25 de sept. de 2004 · An artificial neural network (ANN) model has been developed to predict research octane number (RON) of motor gasoline and compared with a multiple linear regression (MLR) model available in the literature. Further a global optimization technique has been applied to predict probable composition of blends with desired RON and specified properties.

  2. However, these weathering mechanisms generally affect the composition of gasoline in the same manner, and thus, weathering can be observed to follow a fairly standard series of chemical changes. Ratios of certain chemicals, such as BTEX and other ratio compounds, can even be cautiously used to estimate the timeframe of a release if it occurred within the subsurface rather than on the surface ...

  3. Moreover, they mostly produce favorable composition of fatty acids. C18:1 (oleic acid), C16:0 (palmitic acid), and C18:0 (stearic acid) are the principle fatty acids produced by most of the oleaginous yeasts ( Meesters et al., 1996 ) which are also predominant in plant oils used for biodiesel production, such as canola and sunflower oil ( Ageitos, Vallejo, Veiga-Crespo, & Villa, 2011 ; Sitepu ...

  4. 6 de jul. de 2021 · In the framework of reducing GHG emissions and accelerating the decarbonization of the road transport sector, vehicle efficiency is a key factor for competitiveness. In this sense, the refining industry can make its contribution by reformulating high-octane petrol fuel. The impact of this type of gasoline from CO2 emission balance, technical feasibility, and economics standpoints has recently ...

  5. 1 de ene. de 2021 · The B5 oil was also having an analogous density as gasoline. The composition analysis visualized that B5 comprised of alkenes (1.25%), cycloalkanes (3.88%), cycloalkenes (2.43%), aromatics ...

  6. Because straight-run gasoline burns so poorly in engines, petroleum chemists have devised numerous methods for producing higher-quality fuels. One of these methods, ... The final product that goes in your tank has an approximate composition of 15% C 4 –C 8 straight-chain alkanes, 25% to 40% C 4 –C 10 branched-chain alkanes, 10% cyclic ...

  7. When you burn gasoline under ideal conditions, with plenty of oxygen, you get carbon dioxide (from the carbon atoms in gasoline), water (from the hydrogen atoms) and lots of heat. A gallon of gasoline contains about 132x10 6 joules of energy, which is equivalent to 125,000 BTU or 36,650 watt-hours: If you took a 1,500-watt space heater and left ...
