Industrial production process
Traditionally, the most representative of the three manufacturing processes to produce polypropylene. An inert hydrocarbon hydrocarbon diluent slurry or suspension using the liquid in the reactor, in order to transfer to the catalyst for propylene, removal of heat from the system, the inactivation / removal of catalyst, and dissolved atactic polymers. The range of grades can be very limited.
Bulk (or bulk): inert hydrocarbon diluent using liquid propylene, not liquid. The polymer is insoluble in the diluent, but riding on the liquid propylene. The polymer was withdrawn, and any unreacted monomer is flash off.
