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 acentral 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.

1-11. (canceled)
A method of charging a reactor having inlet and outlet ports with a bed of a particulate catalyst comprising providing a first, perforate, catalyst restraining means to define central region within the desired catalyst bed and connected to one of said ports, disposing a second particle restraining means between said first catalyst restraining means and the interior wall of said reactor, filling the space between said first and second restraining means with particulate catalyst and filling the space between the second restraining means and the interior wall of the reactor with a particulate material that presents less resistance to flow than said catalyst particles.
