  1. This calculator helps you determine the octane rating of a blended fuel mixture from two different fuel sources. Fill in the volumes and octane ratings of both fuels and hit the “Calculate” button to get the resulting octane rating of the mixture.

  2. Travelmath provides an online driving cost calculator to help you determine how much you'll spend on gas for your next road trip. You can enter airports, cities, states, countries, or zip codes to compute the cost of driving between locations.

  3. 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).

  4. Octane Calculator. This calculator determines the minimum octane rating, also know as the knock index, by the formula (R+M)/2. Octane rating number is defined as a value used to indicate the resistance of a motor fuel to knock. Octane numbers are based on a scale on which isooctane is 100 (minimal knock) and heptane is 0 (bad knock).

  5. In refining, marginal costs typically drive market prices • Catalytic Reforming units are the primary controllable octane source in the refinery • Refiners can optimize unit throughput and severity (octane of product) • Higher octane results in higher costs • Reformers convert naphtha feedstock into highoctane, high- -aromatics
