Polymer reaction
 

Dear everyone

Now, I'm learning Fluidized bed reactor with polypropylene polymerization.
Catalyst and monomer are fed into the reactor. DEM is used in this case.
In the system,Monomer will react with each other on catalyst surface and fluid domain.
EX A1+A1->A2
A1+A2->A3
A1+A3->A4
A3+A4->A5.........random reaction

Due to polymerization which generate new product along time.

-I need to know Which model can solve my problem.
-I need to know how to define material which change along time.
-How many species should i define?

Please help me!!
