Method for vapor phase polymerization of olefins |
摘要 |
Provided is a method for vapor phase polymerization of olefins. An olefin gas is fed into a horizontal cylindrical vessel having a lower curved surface corresponding to 30 to 180 degrees of the circumference of the vessel and extending substantially the length of the vessel formed by a perforated plate having a multiplicity of holes spaced at intervals in the range of from 0.5 to 50 mm, through said plate from an olefin feed chamber mounted below and covering the plate. A polymer catalyst is fed into the horizontal cylindrical vessel through a polymerization catalyst inlet port located in a portion of the vessel other than the lower curved surface formed by the perforated plate. The olefin is reacted in the presence of a catalyst with agitation to form polymer. Unreacted olefin is removed through a discharge port located in a portion of the vessel other than the lower curved surface formed by the perforated plate. Polymer is removed through an outlet port located in a portion of the vessel other than the lower curved surface formed by the perforated plate.
