A device and a method are disclosed for densely and homogeneously loading catalyst into the annular space of bayonet tubes utilized in a steam reforming reactor. The device is of pneumatic type and uses a detachable feed tube for introducing gas into the annular space.

Pneumatic system for densely loading catalyst into bayonet tubes for a steam reforming reactor-exchanger with a detachable feed tube for gas

The present invention describes a vertical cylindrical exchanger-reactor for carrying out endothermic reactions, comprising a shell enclosing a plurality of tubes inside which the reactive fluid moves, said tubes being of the bayonet type, and the heat transfer fluid, in this case hot gases, being channeled inside chimneys surrounding said bayonet tubes. The bayonet tubes and the chimneys are suspended from the upper dome of the reactor. This reactor may operate with a pressure difference between the tube side and the shell of up to 100 bars. The hot gases are admitted into the reactor at temperatures of up to 1300&#xb0; C.
