Hello. I need to produce a volatilization of three species of particles of carbon, hydrogen, carbon monoxide and methane and see the evolution of the three during the combustion of coal. how can be done? apparently I can only see the evolution of one of these substances. tank you

Hi, How do you know composition of each species that volatilizes from coal. Thanks Venky

Yes, I believe that there is only one variable to accomodate the exchange term. Do you have rate data for the evolution of each of the species as a function of temperature or other parameter? Perhaps you could do something treating it as a surface reaction or use a psuedo species for the volatile intermediate and have that species form the appropriate amounts of your gas species of interest. Good luck.
