LPG Vs. Methanol

Is there a question you want to ask about this or a point you want to raise? It's not very clear.

SIR,

THIS IS A QUESTION .

REGARDS,

RAKESH

Let's hope you are asking to know ---what reactions take place inside a carburizing chamber? where you are Carburizing low cabon surfaces with more carbon to make sharp edges, strengthen etc.

You want to know in particular -- when you inject LPG i.e. C3H8Propane+C4H10 Butane mixture and Methanol=CH3OH

Please confirm -- that is your Question.

If you confirm then the answer is that at 1000C ,all these will break down to make some free carbon =C available for Carburizing.

Dissociation of these yield various combinational equilibria between H2,CO,CO2.H2O & carbonC in a very eplosion-prone environment.

I strongly advise you not to try these when simple pack Carburizing powders are available to do the job..

PRECISELY; THIS IS MY QUESTION. BUT IN OUR CASE, THIS IS UNAVOIDABLE.THE CASE CARBURISING IS CARRIED OUT IN A SEALED QUENCH FURNACE AT 920CENTIGRADE. IF YOU COULD ELABORATE MORE ON THESE REACTIONS.

YES. MORE PARTICULARLY IF THESE CHEMICALS ARE UNAVOIDABLE. THEN IN WHAT RATIO AND AT WHAT DIFFERENT TEMPERATURES THEY SHOULD BE INJECTED SO THAT THERE IS LEAST SOOT FORMATION OR MORE PRECISELY WHAT LEADS TO SOOT FORMATION IN A SEALED QUENCH FURNACE AND HOW IT COULD BE AVOIDED.WHAT CHEMICAL REACTIONS ARE INVOLVED THEREIN.
