Hello!
Could you please check the following sentences? Thank you.
Oil is a compound of liquid hydrocarbons in which dissolved hydrocarbon gases can be found, as well as solid particles and other substances up to 5 per cent of the mass share/portion(compounds which contain sulfur, nitrogen and oxygen). Hydrocarbons are paraffin, armoatic and naften structures.

The way I understand it, you don't need either, Antonia. I'd move the parenthetical part, though: Oil is a compound of liquid hydrocarbons in which dissolved hydrocarbon gases can be found, as well as solid particles and other substances (compounds which contain sulfur, nitrogen and oxygen) up to 5 per cent of the mass . Hydrocarbons are paraffin, aromatic and naften structures.

- PS: I don't know what naften is, but I think it is naphtha in English.

Nothing to add except the last sentence:
Hydrocarbons are paraffins, aromatic and naphthene structures.
Parafin is a fuel and is a physical mixture of several different hydrocarbons and also usually with a colourant and an odour added.
Paraffins are a class of compunds containing only carbon and hydrogen. Paraffins is the colloquial name and alkanes is the chemical spec

Oil is a hydrocarbon in liquid form which contains dissolved hydrocarbon gases.
In addition it also contains solid particles and other substances (compounds which contain sulphur, nitrogen and oxygen) which can make (or,which can total) up to 5 percent of its mass. Hydrocarbons are paraffin, aromatic and naptha structures.
