The solutions of hydrogen

Hydrogen solutions - Feedstock for chemical production

Sulphur compounds present in crude oil form sulphur dioxide when they are burned. Since this gas contributes to acid rain, the sulphur compounds are removed during oil refining. Oil fractions are passed over a catalyst, and reacted with hydrogen under high temperature and pressure to produce hydrogen sulphide. This gas is separated and converted to sulphur for removal.

Hydrogen is used in the manufacture of ammonia.
Ammonia, used for fertilisers, explosives and dyes, is produced using the Haber process. In this process, hydrogen and nitrogen react together in the presence of an iron catalyst at around 450 °C and 20 MPa pressure.

Hydrogen was used to power NASA's Saturn V rockets which took people to the moon.

So why use liquid hydrogen for rocket engines instead of petrol? Hydrogen is highly flammable. It can be stored as a gas under pressure or as a liquid at -253 °C. Compared to the same mass of petrol, liquid hydrogen stores three times more energy but it occupies ten times the volume. A larger fuel tank may be needed if liquid hydrogen is used, but the mass of the fuel is a third of the ma
ss needed if petrol were to be used. This allows a much heavier payload to be carried into space.
