   We can model the heating values by using standard heats of combustion 1 for iso-octane and cetane. Engineers distinguish between higher heating value (HHV) 1 and lower heating value (LHV) 1 of a fuel. HHV corresponds to the standard heat of combustion where the product water is condensed to its liquid state.

   To assess octane costs, this study examines trends at the national, the Petroleum Administration for Defense District (PADD), and the regional wholesale market levels. The market for motor gasoline is global, and the U.S. gasoline market is interconnected with the global gasoline market through imports and exports.

   octane. This compares to regular grade gasoline which is 87 octane. Higher octane fuel aims to provide greater fuel-burning stability to protect engines from the damage caused by engine knock –also known as abnormal combustion. Before the use of computerized ignition systems, engine knock was more common, particularly in high-compression ...

   Octane costs and values are often described in terms of dollars per octane-barrel ($/AKI-b).21 To measure the cost of producing incremental octane, we calculate the cost of producing an incremental barrel of premium gasoline (CTP) by raising reformer severity (Figure 29, red and black lines).

   How much does octane cost?

   • Octane values have increased from about 1 $/RON-b to 2.75 $/ RON-b as of 2017 (Figure 57, blue line represents octane cost while the red dashed line represents the crude cost). Unlike the U.S (Section 6.5, Figure 29), octane costs have not dropped back down to 2011 levels.

   What is a gasoline octane rating?

   • The gasoline octane rating measures its ability to withstand pre-ignition during compression in an engine cylinder. Gasoline octane is a critical factor in engine design. Engine performance and efficiency increase with increasing compression ratio. Engines with higher compression ratios require gasolines with higher octane ratings.

   Do isomerization units increase octane ratings?

   • Isomerization units increase octane ratings of LSR but also increase its RVP, limiting the use of isomerization units in increasing the octane ratings of finished gasoline. In FCC and hydrocracking units, most of the products have lower densities than the feed. Therefore the total volume of products exceeds the volume of the feed.
