A gas-agitated multiphase reactor system that is effective for enabling maximum reactor productivity or minimizing reactor volume comprising at least two stages with or without recycle, wherein inlet gas superficial velocity is at least 20 cm/sec at Fischer-Tropsch synthesis, yielding a total syngas

A gas-agitated multiphase reactor system that is effective for enabling maximum reactor productivity or minimizing reactor volume comprising at least two stages with or without recycle, wherein inlet gas superficial velocity is at least 20 cm/sec at Fischer-Tropsch synthesis, yielding a total syngas conversion of greater than about 90%, while syngas conversion in each reactor is less than 60%. More specifically, the total reactor volume is held to a minimum such that minimum reactor volume is less than 0.02 cubic meters total reactor volume/(kg C5+ /hr production).

What is claimed is: 1. A method for maximizing the production rate of a gas-agitated multiphase reactor system comprising: providing a gas-agitated multiphase reactor system comprising at least two reactor stages, each stage comprising at least one reactor receiving an syngas-containing inlet stream at an inlet gas superficial velocity and generating a product stream, wherein the inlet gas superficial velocity in each reactor is at least 20 cm/sec; and operating each reactor stage to convert syngas to hydrocarbons such that overall syngas conversion for the reactor system is at least about 84%, while syngas per pass conversion in each reactor is less than 60%; and wherein the gas-agitated multiphase reactor system has an overall C5+ volumetric production rate greater than about 50 kilograms C5+ hydrocarbon/hr/m3 expanded catalyst bed. 2. A method for operating a gas-agitated multiphase reactor system for hydrocarbon production from syngas, comprising: providing a gas-agitated multiphase reactor system comprising at least two reactor stages and a condensing stage between said first and second reactor stages, wherein each reactor stage comprises at least one reactor receiving a syngas-containing feed stream and generating a product stream; passing at least a portion of the product stream from the at least one reactor of the first stage through the condensing stage to produce a condensed stream and a gaseous remainder stream comprising uncondensed light components of said portion of the product stream, wherein the syngas-containing feed stream of the at least one reactor of the second reactor stage comprises at least a portion of the gaseous remainder stream; and operating each reactor stage to convert syngas to hydrocarbons such that each reactor has a syngas per pass conversion of less than 60%, while the reactor system has an overall syngas conversion of at least about 84% and an overall C5+ hydrocarbons volumetric production rate greater than about 50 kilograms C5+ hydrocarbon/hr/m3 total reactor volume. 3. The method of claim 2 wherein each reactor has a water partial pressure of less than 150 psig. 4. The method of claim 2 wherein a portion of said gaseous remainder stream is recycled back to mix with the syngas-containing feed stream of at least one reactor in the first reactor stage. 5. The method of claim 2, wherein no portion of said gaseous remainder stream is recycled back to the first reactor stage. 6. The method of claim 4, wherein the syngas-containing feed stream of each reactor has an inlet gas superficial velocity of at least 20 cm/sec.
