Olefin polymerization reactor, polyolefin production system, and polyolefin production process

摘要

An olefin polymerization reactor is provided with a first cylinder extending vertically; a first tapered cylindrical member placed in the first cylinder, having the inner diameter decreasing progressively downward, and having a gas inlet orifice at a bottom end thereof; a first liquid supplying part supplying a liquid so that the liquid may come into contact with an outer surface of the first tapered cylindrical member; and a gas supplying part supplying an olefin-containing gas through the gas inlet orifice into a first reaction region surrounded by an inner surface of the first tapered cylindrical member and an inner surface of the first cylinder above the first tapered cylindrical member, to form a spouted bed in the first reaction region.
