1. Why we are using hydrogen for desulphurisation and cracking operations? And what other gases which can be used instead of hydrogen ? Kindly clear this doubt.
2. Why nitrogen is called as inert gas? Does it mean that it wont react with anything?

This query is in a professional Forum. It is so basic and elementary that it belongs in a student Forum. However, it may be a layperson asking for help or guidance so I’ll add my responses:

• Why we are using hydrogen for desulphurisation and cracking operations? And what other gases which can be used instead of hydrogen? Kindly clear this doubt.

To remove sulfur from a hydrocarbon mixture – as in a heavy crude oil, hydrogen is used to combine with the sulfur to produce hydrogen sulfide (a gas) that is subsequently easily removed. No other gas can be used.

• Why nitrogen is called as inert gas? Does it mean that it won’t react with anything?

Nitrogen is called an inert gas because it is an inert substance. It doesn’t react on its own. It will not react under normal conditions and requires large amounts of energy and catalytic action to participate in a reaction.
