spouted bed / fluidized bed - olefin polymerization reactor

摘要

By means of the present invention, an olefin polymerization reactor is provided, comprising: a vertically extending cylinder; a portion provided on the cylinder, with decreasing diameter with an inside diameter, the downwardly steadily decreases, and with a gas inlet opening formed at a lower end; and a plurality of through holes which are derived from an outer surface to an inner surface of the section with a decreasing diameter, extend toward. In the interior of a enlarging which, by an inner surface of the section with a decreasing diameter and an inner surface above the cylinder section is surrounded with a decreasing diameter, a spouted bed / fluidized bed or to a formed spouted bed.
