Patent

CA 2306173

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~ and the fluidised bed being higher than the cylindrical part.

L'invention concerne un réacteur à lit fluidisé (13) servant à produire notamment du caoutchouc dans la phase gazeuse. La paroi de ce réacteur se présente, dans sa partie inférieure, sous la forme d'un cylindre (2) se prolongeant ensuite sous la forme d'un cône (3) s'ouvrant de façon continue. L'angle formé par le cône (3) par rapport à l'axe central est compris entre 2 et 10· et la hauteur du lit fluidisé est supérieure à celle de la partie cylindrique.
