light benzine

Question

Is 'light benzine' Ok? Have I used 'octanic number' properly?Isomerization: chief purpose of this process is an increase of octanic number of light benzine (C5-78°C).

Alan.es · Accepted Answer

I think it's 'octane number'.

Thw whole paragraph will make certain if you can copy and paste it.

Hi Alan,

I'm afraid this is the whole paragrah:

Conversion processes:alkylation, isomerization and catalytic reforming

These are secondary, catalytic processes for obtaining purified, high quality benzines for blending. Various catalysts are used: sulphuric or hydrofluoric Acid (H2SO4 or HF), platinum sulphur compound, halides of aluminium or antimony, molybdenum, cobalt and others.

Alkylation is a secondary process of oil processing which enables the production of the best quality benzines which are used for blending.

Isomerization: chief purpose of this process is an increase of octanic number of light benzine (C5-78°C).

Catalytic reforming: benzine fraction (78-180°C) obtained by the process of atmospheric distillation can not be useed as a component for petrol blending because it contains sulfurous compounds and has low octanic number (due to the high content of n-parafine and naften and very low content of aromats). It can be used only as a raw material for petrochemical industry (base petrol). To increase the octanic number in this fraction, as well as to use it for blending petrol, it is sent for catalytic reforming plant. Prior to that it is necessary to refine it on the hydrodesulphurisation plant to remove sulfurous compounds and metals from it (Pb, S, Hs).

Don't worry - with cut and paste, it's much easier to see the whole context and correct it 'in situ'

OK :-

Alkylation is a secondary process of oil processing which enables the production of the best quality benzines which are used for blending.

Isomerization: chief purpose of this process is an increase in the octane number of light benzine (C5-78°C).

Catalytic reforming: benzine fraction (78-180°C) obtained by the process of atmospheric distillation can not be used as a component for petrol blending because it contains sulfur compounds and has a low octane number (due to the high content of n-parafins and napthenes but very low content of aromatics). It can only be used as a raw material for the petrochemical industry (base petrol). To increase the octane number in this fraction, so it can be used for blending petrol, it is sent to the catalytic reforming plant. Prior to that it is necessary to refine it in the hydrodesulphurisation plant so removing sulphur compounds and metals from it (Pb, S, Hs).

Note - I don't recognise 'Hs' as a chemical symbol. Can you check it?

BTW, We, English, use sulphur. The US use 'sulfur'. :-) It doesn't really matter but you need to be consistent.

Hi Alan,

Thank you very much for your help.

Hs - Hassium.

Thank you once again for your notes and comments.I have corrected AE sulfur into sulphur.

Alan.es · Answer

Hassium is a synthetic element that is not present in the environment at all.

It can't be Hassium, even though you sprang a surprise on me. One that's been made synthetically since my time as an active chemist.

It could be As, arsenic, or H2S, hydrogen sulphide, or something else but not Hassium.

Antonija · Answer

I don't know, either. I have checked Hs on the google, and that's how I came with Hassium. To be honest, I had never heard of it before. I guess, this is another thing I'll have to ask the author.
