Claim Text:
1. A method for converting synthesis gas into liquid hydrocarbons, the method comprising: introducing a synthesis gas feed into a Fischer-Tropsch reactor of a Fischer-Tropsch system at a superficial gas velocity greater than the average sedimentation velocity and/or greater than the minimum fluidization velocity of catalyst in the catalytic reactor, wherein the Fischer-Tropsch system comprises: a catalytic reactor fluidly connected with at least two slurry loops, wherein the reactor comprises at least as many reactor product outlets and at least as many slurry return inlets as slurry loops; wherein each slurry loop comprises a separation system comprising at least one separator for separating concentrated catalyst slurry from liquid product; an inlet of the at least one separator fluidly connected to one of the reactor product outlets via a slurry offtake, an outlet of the at least one separator fluidly connected to one of the slurry return inlets via a slurry return, and a product outlet of the at least one separator for removal of liquid product therefrom; separating concentrated catalyst slurry from the reaction product via the at least two slurry loops; removing liquid hydrocarbon product from the at least one separator of each of the at least two slurry loops; and returning concentrated catalyst slurry to the catalytic reactor via the at least as many slurry returns and the at least as many slurry return inlets, wherein at least one separator of at least one of the separation systems comprises a magnetic dynamic separation vessel comprising a vertical feed conduit fluidly connected with an inlet of the magnetic dynamic separation vessel, and the vertical feed conduit is located at a side of the magnetic dynamic settling vessel and extends at least 70% of the length of the magnetic dynamic separation vessel.
