Traditionally, the most representative of the three manufacturing processes has been used to produce polypropylene. Hydrocarbon slurry or suspension A liquid inert inert diluent used in the reactor to transfer propylene to the catalyst, heat removed from the system, deactivated/removed catalyst, and dissolved atactic polymer. The range in which the grades can be produced is very limited. (This technology is no longer used).
Bulk (or large amount of pulp): An inert hydrocarbon diluent that uses liquid propylene instead of liquid. The polymer is insoluble in the diluent but rides in liquid propylene. The formed polymer was withdrawn and any unreacted monomer was flashed off.
Gas phase: The use of gaseous propylene in contact with a solid catalyst results in a fluidized bed medium.
