Thekerosene (orkerosene), is a mixture of hydrocarbons mainly used asfuel. There kerosene production, until today, it takes place by fractional distillation of petroleum from 150 ° C to 280 ° C, thus obtaining carbon chains from 12 to 15 atoms. Inkerosene, the content of aromatic compounds can reach 25 percent. The calorific value ofkeroseneis very similar to that of thediesel fueland is between 43.1 MJ / kg (minimum value) and 46.2 MJ / kg (maximum).

Therekerosene productioncan be accomplished by ahydrocracker, used to transform the parts of crude oil that would otherwise be discarded as heavy oil.

As is clear, thekerosene thus produced it is a derivative of petroleum and for this reason it is a non-renewable energy source. The researchers of the projectSolar-JETthey managed to start thekerosene productionstarting from "zero"and solar energy.

The projectSolar-JET, funded by the Seventh European Framework Program for Research and Technological Development, gave birth to thekerosene productionstarting from carbon dioxide, water and a reactor powered by sunlight. The reactor prototype was able to produce small quantities ofkerosenebut by applying the concept on a large scale, one can be achievedkerosene productionequal to 20,000 liters of fuel per day.

Such an application may be capable ofto recyclecarbon dioxide and convert it back into keroseneor even other fuels such as petrol and diesel. A fundamental step that would bring greater energy security, in addition, to produce a fuel would be to reuse one of the main greenhouse gases responsible for global warming.

Forproduce kerosenethe researchers reacted H2O (water) and CO2 (carbon dioxide, carbon dioxide) in a solar reactor heated to 1292 Fahrenheit, 700 C.

Oil companies such as Shell employ similar technology to produce here defined fuelsSyngas, in this case the temperatures reached go beyond 2,200 C, 3,992 F. When the solar reactor is perfected, even the big oil companies will be able to count on greener technology. Another strong point of the solar reactor is that the resulting fuels are perfect for powering modern internal combustion engines of cars and aircraft, so no modifications to the engine will be required.
