The fuel factor, f o, is the ratio of created CO 2 to depleted oxygen in a combustion reaction, used to check the accuracy of an emission measurement system. [1] It can be calculated using the equation f o = (20.9 - %O 2)/%CO 2,
Then a full-scale commercial TCC unit processing 10,000 barrels per day (1,600 m 3 /d) began operation in 1943 at the Beaumont, Texas refinery of Magnolia Oil Company, an affiliate of Socony-Vacuum. By the end of World War II in 1945, the processing capacity of the TCC units in operation was about 300,000 barrels per day (48,000 m 3 /d).
Due to the higher density, diesel fuel offers a higher volumetric energy density: the density of EN 590 diesel fuel is defined as 0.820 to 0.845 kg/L (6.84 to 7.05 lb/US gal) at 15 °C (59 °F), about 9.0-13.9% more than EN 228 gasoline (petrol)'s 0.720–0.775 kg/L (6.01–6.47 lb/US gal) at 15 °C, which should be put into consideration when ...
A diesel cycle engine can be as much as 40% to 50% efficient at converting fuel into work, [2] where a typical automotive gasoline engine's efficiency is about 25% to 30%. [3] [4] In general, an engine is designed to run on a single fuel source and substituting one fuel for another may affect the thermal efficiency.
The cost of conversion may be justified in areas where aviation gasoline costs significantly more than jet fuel, and by the fact that the diesel fuel flow at cruise is about 10 gallons (38 litres) per hour, compared to about 13.5 gallons (51 litres) per hour with the original engine.
Gas to liquids (GTL) is a refinery process to convert natural gas or other gaseous hydrocarbons into longer-chain hydrocarbons, such as gasoline or diesel fuel. Methane-rich gases are converted into liquid synthetic fuels.
The dual-fuel ferry has more car capacity but requires larger engines which also emit methane, a greenhouse gas with a far greater global warming effect than CO2.
Carbon-neutral fuel is fuel which produces no net-greenhouse gas emissions or carbon footprint. In practice, this usually means fuels that are made using carbon dioxide (CO 2 ) as a feedstock . Proposed carbon-neutral fuels can broadly be grouped into synthetic fuels , which are made by chemically hydrogenating carbon dioxide, and biofuels ...
