【発明の名称】有機金属化合物を導入して流動床反応器中でオレフィン類をガス相重合化する装置及び方法

Document Type and Number:

Japanese Patent JP2755699

Kind Code:

B2

Abstract:

A process for polymerising olefins in the presence of a Ziegler-Natta type catalyst or a catalyst based on chromium oxide using a gas-phase fluidised-bed reactor (1) having a recycle line (5) for removing the olefin-containing gas from the top of the reactor and returning it to the bottom of the reactor, the recycle line having at least one heat exchanger (7,10) for cooling the olefin-containing gas, which process comprises introducing an organometallic compound, as a mixture or as a solution in at least one C3 to C12 liquid olefin, into the recycle line at a point upstream of a heat exchanger (10).
