aThe demand for lighter products, such as Gasoline, Kerosene and Diesel is much higher than the demand for heavier products 对更轻的产品的需求,例如汽油、煤油和柴油对更重的产品的需求高于[translate]
Gasoline has a specific gravity between 0.71 and 0.77, depending on its precise composition. Aromatic compounds are less dense than aliphatic compounds, so the specific gravity of gasoline can indicate the relative proportion of these compounds in the gasoline. Gasoline Chemical Properties What's the ...
What component of gasoline gives it such a high enthalpy of combustion? a. hydrocarbons b. hydrogen c. carbon d. magnesium e. none of the above What mass of carbon dioxide is formed by the complete combustion of 760 g of ethanol?
Fuel with an octane rating of 87 is less resistant to detonation than fuel with a rating of 89 or 91.A gasoline's octane rating can be improved by additional refining to increase the proportion of heavier hydrocarbons in the fuel, by using a higher grade crude stock or by adding ethanol ...
gasoline with cleaner-burning fuel such as compressed natural gas, liquefied petroleum gas, ethanol, or methanol. All of these alternatives are carbon-based fuels whose molecules are smaller and simpler than those of gasoline. These molecules burn more cleanly than gasoline, in part because they ...
PETROLEUM ETHER, also known as petroleum ether, is a colorless and transparent liquid with a gasoline-like odor. It is mainly a mixture of pentane and hexane. It is insoluble in water but soluble in anhydrous ethanol, benzene, chloroform, and other organic solvents. It is highly flammable and...
Gasoline Engines: With the invention of the internal combustion engine, and the advent of gasoline automobiles in 1885 by Karl Benz, petroleum soon became a sought after energy source. Electricity: With the perfection of the electric light in 1879, Thomas Edison had enlightened the world. However...

heavier oligomers (typically the C10 or C11+ molecules, except for the tetramer (mainly C12) that is made from propylene), and the molecules that are not directly made by oligomerisation of fresh feed olefins, but made via a mechanism involving cracking to other than those fresh feed olefins...
As energy carriers, fuel (liquid hydrogen, ethanol, gasoline, other type of fuel (explosive)) and oxidizing agent (liquid oxygen, air, etc.) can be used. The combustion process renders energy to the cutting process in different manners: mechanical movement of turbine, cutting water pressure, ...
