Industrial process
Traditionally, three manufacturing processes are most representative of the way polypropylene is produced. Hydrocarbon slurry or suspension used in the reactor as an inert hydrocarbon diluent of the liquid in order to transfer the propylene to the catalyst, remove the heat from the system, deactivate/remove the catalyst, and dissolve the atonic polymer. The range of brands that can be produced is very limited. (This technology is no longer used).
Bulk (or bulk pulp) : Use liquid propylene instead of liquid inert hydrocarbon thinner. The polymer is insoluble in thinner, but rides on liquid propylene. The resulting polymer is withdrawn and any unreacted monomers are flash away.
Gas phase: Use gaseous propylene in contact with a solid catalyst resulting in a fluidized bed medium.
