Abstract
An axial/radial—or radial/flow catalytic reactor has inlet and outlet ports and a bed of particulate catalyst disposed as e.g. a cylinder or cone round a central region communicating with one of the ports. For at least part of the height of the catalyst bed, the exterior surface of the catalyst bed has a diameter less than that of the reactor thus leaving space between the exterior surface of the catalyst bed and the interior walls of the reactor. This space is filled with a particulate material presenting less resistance to flow than the catalyst particles.
Claims11
A catalytic reactor having inlet and outlet ports and a bed of particulate catalyst disposed round a central region communicating with one of the ports and presenting less resistance to flow than the catalyst particles, said central region within the bed having a height equal to at least a major part of the height of the catalyst bed, and, for at least a major part of the height of the catalyst bed, the minimum diameter of the exterior surface of the catalyst bed is less than the interior diameter of the reactor, thus leaving a space between the exterior surface of the catalyst bed and the interior walls of the reactor, wherein said space is filled with a particulate material presenting less resistance to flow than the catalyst particles.
