Abstract
The present invention comprises a fixed bed reactor, a method of loading catalyst into the reactor to minimize plugging and to improve the uniformity of fluid flow across the reactor, and a hydrotreating process employing the novel reactor. The system utilizes removable partition forms and/or permanent interbed baskets to create gradual transition zones between catalyst layers and to significantly increase the open area available for flow at the interface of such zones.
