Abstract
Methods for reducing the average molecular weight of liquid hydrocarbons in a Fischer-Tropsch reactor are disclosed. The preferred embodiments of the present invention are characterized by feeding a hydrocarbon stream, which lowers the average molecular weight of the hydrocarbon liquids inside the reactor, and more preferably by recycling a portion of low-molecular weight hydrocarbon products back into the reactor. Lowering the molecular weight of the hydrocarbon liquids inside the reactor increases the mass transfer and solubility, and diffusivity of the reactants in the hydrocarbons present in the slurry.
