ABSTRACT A continuous reaction process and apparatus wherein a liquid or slurry is contacted with gas in an ebullated cata- lyst bed reaction zone,with the liquid and gases flowing upwardly through the reaction zone into a phase separation zone substantially free of catalyst particles. The liquid and gases are separated by a phase separation-collection device, and the liquid portion is collected and recycled through a central conduit by a recycle pump having its impeller located in the upper portion of the conduit. The pump impeller bearing is pressurized and purged by a clean com- patible fluid, such as hydrogen or oil, to exclude reactor liquid containing fine solids from the bearing and seal surfaces. A second liquid recycle pump can be provided at the lower end of the reactor and operated in series flow relationship with the upper pump. The second pump can be located either within the reactor vessel or external to it and connected thereto by conduits.
