Octane barrel yield

Octane Barrel Yield, as used in the FCC, is defined as (RON -i- MON)/2 times the gasoline yield. 

Yields Ethylene yields from a naphtha cracker can be increased by over 30% using MaxEne extract as feedstock and the MaxEne raffinate can provide a 6% increase in octane-barrels from a refiner s catalytic naphtha reforming unit. 

The Houdry process was eminently successful and soon demonstrated its ability to produce good yields of high-octane gasoline from a wide variety of charging stocks. Twenty-nine of these units were built in the United States and foreign countries, the combined capacity being about 375,000 barrels/day (51). 

Note Gasoline of 94 octane can be produced from residual oil in a high-temperature catalytic process, thus increasing the yield of gasoline from a barrel of crude by 33% when full-scale production is achieved. 

The Houdry units greatly increased both the quality and the yield of gasoline per barrel of crude, and during World War II high octane Houdry gasoline propelled the Royal Air Force to victory in the battle of Britain.
