摘要： 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.

摘要： A method for selecting maximum and minimum catalyst particle sizes for use in a multiphase reactor that reflects optimum operating conditions of the reactor is based on a maximum Archimedes number for estimating the maximum particle size and a property of a separation system linked to the reactor to determine the minimum particle size. The maximum Archimedes number could be selected based on a maximum catalyst non-uniformity in the reactor. Additionally, a method for producing hydrocarbons from syngas in a slurry bubble column reactor comprises the use of a plurality of fresh catalyst particles with an optimum size distribution based on a range of Archimedes numbers between about 0.02 and 250 or alternatively based on an average Reynolds number less than about 0.1.

摘要： The present invention relates to a method and apparatus for reducing the maximum water concentration in multi-phase reactors operating at Fischer-Tropsch conditions. In a preferred embodiment of the present invention, a method of reducing the maximum concentration of water in a multi-phase reactor containing an expanded slurry bed and a water-rich slurry region for Fisher-Tropsch synthesis includes changing the flow structure of a predetermined region in the reactor. The flow structure may be changed by introducing a mixing enhancing fluid into the predetermined region, installing baffles into the predetermined region, or by other methods known in the art. Preferably the predetermined region is located between ½ H and H and between ½ R and R, where H is the height of the expanded slurry bed and R is the radius of the reactor.
