GAS PHASE POLYMERISATION IN A BELL-SHAPED REACTOR

摘要

A fluidised bed reactor (13), in particular for producing rubber in the gaseous phase, has a wall shaped in its lower part as a cylinder (2) which then flares continuously outwards, forming a cone (3), the cone (3) angle with respect to the centre line being equal to 2 to 10 DEG and the fluidised bed being higher than the cylindrical part.
