Higher is the octane number higher is the activation energies. Activation energy is the amount of energy required to initiate combustion. 

• The fuels with higher octane ratings will require high activation energies and are less prone to auto-ignition.
• They can withstand the greater rise in temperature during the compression stroke of an internal combustion engine without auto igniting and thus allow more power to be extracted.
• They have lower cetane number. Cetane number and octane rating are opposite to each other.
• A fuel with higher octane rating leads to less engine knocking.
  

Octane number can be determined by RON, MON and AKI. The most common method used for the measurement is RON. RON is determined by running the fuel in a test engine and comparing the results with those for mixtures of iso-octane and $n$- heptane. The RON/MON values of iso-octane is 100.

In catalytic reforming process, the noble metals platinum and rhenium are the catalysts used on a silica or silica-alumina support base. Fresh catalyst is chlorinated prior to use. On the other hand, an excessive chlorination could depress excessively the activity of the catalyst. Also in the case of the semi-regenerative catalytic reformer, the catalyst is reduced over time by carbonaceous coke deposition and chlorine loss.

In catalytic reforming process, high octane number reformate is formed which is the main component of the motor, fuel, aviation gasoline or aromatic rich feedstock. The noble metals platinum and rhenium are the catalysts used on a silica or silica-alumina support base. Fresh catalyst is chlorinated prior to use.

Hydrogenolysis is a reaction where hydrogen is added to a compound and breaks that compound’s bonds, forming two molecules. This results in the formation of lighter hydrocarbons.

In catalytic reforming process, high octane number reformate is formed which is the main component of a motor, fuel, aviation gasoline or aromatic rich feedstock. The noble metals platinum and rhenium are the catalysts used for it.

Catalytic reforming is a chemical process that is used to convert petroleum refinery naphthas, typically those which are having lower octane ratings into high octane liquid products which are termed as reformates. They are the components of high octane gasoline.
