The NRL process begins
by extracting carbon dioxide and hydrogen from seawater.As seawater passes
through a sepcially built cell, it is subjected to a small electric current.This causes the
seawater to exchange hydrogen ions produced at the anode with sodium ions.As a result, the
seawater is acidified.
Meanwhile, at the
cathode, the water is reduced to hydrogen gas and sodium hydroxide is formed.The end product is
hydrogen and carbon dioxide gas, and the sodium hydroxide is added to the
leftover seawater to neutralize its acidity.
In the next step, the
hydrogen and carbon dioxide are passed into a heated reaction chamber with an
iron catalyst.The gases combine and
form long-chained unsaturated hydrocarbons with methane as a by-product.
The unsaturated
hydrocarbons are then made to form longer hydrocarbon molecules containing six
to nine carbon atoms.Using a
nickel-supported catalyst, these are then converted into jet fuel.
