<h3>What is Gasoline?</h3>
Gasoline is one of the most refined products that leave the refinery.
Automotive Gasoline is derived from relatively light fractions (C4-C12) by combining the products of various refinery activities, including isomerization, reforming, cracking, and alkylation reactions.
If Gasoline were solely the result of straight run fractional distillation, its composition would differ greatly and it would be an inadequate fuel for internal combustion engines.
Because lead-based chemicals can no longer be added to most Gasoline, the octane number is primarily improved by increasing the relative proportion of aromatic compounds and isoparaffins. .
Gasoline contains nearly all types of hydrocarbons in the C4 to C12 range, but is dominated by aromatic compounds, with alkylbenzenes being the most numerous and naphthalene- and indane-based compounds being less abundant.
