Disclosed is a highly productive polymerization method of alpha-olefins, using an internal-circulation-type fluidized bed polymerization reactor. The gas-phase polymerization method of alpha-olefins includes: supplying a circulating gas including alpha-olefins and/or an inert gas to a reactor; polymerizing the alpha-olefins into a polyolefin in two separate polymerization regions within the reactor; and removing the produced polyolefin polymer from the reactor. The reactor is divided into the two polymerization regions by a draft tube; an internal portion of the draft tube forms a riser region in which the growing polyolefin polymer rises and moves in high-speed fluidizing conditions, an external portion of the draft tube forms an annulus region in which the polyolefin polymer passing through the riser region drops and moves by means of gravitational force, the polyolefin polymer passing through the annulus region is reintroduced into a lower portion of the riser region, and the polyolefin polymer is polymerized while being circulated in the riser region and in the annulus region.

Abrégé

The present invention relates to a process of preparing of a phosphorus-containing phosphorus-alumina support by a sol-gel method and a cobalt/phosphorus-alumina catalyst where cobalt is supported onto the phosphorus-alumina support as an active ingredient. The phosphorus-alumina support is prepared by a sol-gel method and has wide specific surface area with bimodal pore size distribution and high cobalt dispersion, thereby enabling to increase heat and mass transfer, stabilize the structure by modifying the surface property of alumina and decrease the deactivation rate due to the reduced oxidation of cobalt component during the F-T reaction. When Fischer-Tropsch reaction (F-T) is conducted on the catalyst, the catalyst maintains a superior thermal stability, inhibits the deactivation due to water generation during the F-T reaction and also causes relatively high conversion of carbon monoxide and stable selectivity of liquid hydrocarbons.
