Gas phases - fluidized bed reactor, more vessel - polymerization reactor and process for the olefin polymer production

摘要

Gas phases - fluidized-bed reactor, which is a reaction by supplying a gas by means of a gas distribution plate lying on the lower part of a reaction vessel into a fluidized bed formed on the gas distribution plate performs,the reaction vessel is constructed so that the gas flow passage through the gas distribution plate a constriction at a fixed position and hasthe fluidized bed in the field of below to above the constriction is formed.
