摘要: Process for polymerizing one or more olefinic monomers in a fluid-bed reactor which is bounded at the bottom by a gas-distributing plate containing apertures, comprising the supply of a gas to the reactor through the gas-distributing plate and optionally the supply of a liquid to the reactor, in which the average rate at which the gas is supplied to the reactor is higher in a first part of the gas-distributing plate whose area equals half that of the gas-distributing plate than the average rate at which the gas is supplied in a second part covering the area of the gas-distributing plate that lies outside the first part and reactor suitable for this process.
