Gas phase polymerization method of alpha-olefin |
| abstract |
Disclosed is a method for inducing internal circulation of polyolefin particles by increasing the internal circulation fluidized bed polymerization reactor, increasing the contact time with the circulating gas, and polymerizing alpha-olefin with high productivity. The gas phase polymerization method of the alpha-olefin may include supplying a circulating gas including at least one alpha-olefin and an inert gas to the reactor; Polymerizing the alpha-olefin into a polyolefin in two separate polymerization zones inside the reactor; And evacuating the resulting polyolefin polymer from the reactor. Here, the reactor is divided into two polymerization zones by a draft tube, and the inside of the draft tube forms a riser region in which the growing polyolefin polymer moves up at high fluidization conditions. The outer side forms an annulus region in which the polyolefin polymer passing through the riser region is moved downward by gravity, and the polyolefin polymer passing through the annulus region is again introduced into the lower portion of the riser region, so that the polyolefin The polymer polymerizes while circulating through the riser and annular regions. |
