1. A process comprising:
preparing a first catalyst slurry comprising a solid particulate catalyst and a carrier liquid in a catalyst slurry preparation system,
wherein the catalyst slurry preparation system comprises:
a first mixing vessel,
a first rotatable impeller system connected to the first mixing vessel, and
a first motor connected to the first rotatable impeller system,
wherein the first rotatable impeller system comprises an agitator shaft and at least two hubs connected to the agitator shaft, wherein the at least two hubs and at least a portion of the agitator shaft are positioned within the first mixing vessel along a longitudinal axis of the first mixing vessel, and wherein each of the at least two hubs comprise at least two blades;
preparing a second catalyst slurry comprising the solid particulate catalyst and the carrier liquid in the catalyst slurry preparation system,
wherein the catalyst slurry preparation system further comprises:
a second mixing vessel,
a second rotatable impeller system connected to the second mixing vessel, and
a second motor connected to the second rotatable impeller system,
wherein the second rotatable impeller system comprises an agitator shaft and at least two hubs connected to the agitator shaft, wherein the at least two hubs and at least a portion of the agitator shaft are positioned within the second mixing vessel along a longitudinal axis of the second mixing vessel, wherein each of the at least two hubs comprise at least two blades,
wherein an outlet of the second mixing vessel is connected to an inlet of the first mixing vessel, and
wherein a first concentration of the solid particulate catalyst in the first catalyst slurry is about equal to or greater than a second concentration of the solid particulate catalyst in the second catalyst slurry.
