An improved gas phase reactor system has been designed and tested in order to study heat transfer in gas phase olefin polymerisation on supported catalysts. It is shown that temperature rise in a fixed bed configuration is highly dependent on the flow rate of gas, with higher outlet gas temperatures being observed at higher flow rates. In addition it is shown that the shape of the rate curve is dependent on the initial conditions of the reaction, suggesting that the mechanism of particle fragmentation depends to a certain extent on the start‐up of the reaction.
