In the light of the stringent environmental laws, isomerization is a good process as it enhances the octane number of hydrocarbons especially lighter hydrocarbon in the range of C5-C6 by converting their straight-chain structure into branched chain structure without producing aromatics in the products [3].
The fuel matrix was designed to hold the research octane number (RON) constant at 98 while investigating two different levels of heat of vaporization (HoV) and two different levels of octane sensitivity (S), where S is the difference between RON and the Motor Octane Number (MON) as shown in Equation 1.
Octane number is a measure of how well a fuel resists knock - an abnormal combustion process where the combustion of fuel/air mixture occurs spontaneously in the end gas rather than within a flame front initiated by spark ignition.
