Features of the Fischer–Tropsch Synthesis of Hydrocarbons in the Presence of Dispersed Iron-Containing Systems with Varying Slurry Phase Particle Diameter

Abstract

The laws governing the formation of nanoscale iron-containing disperse systems with a dispersed-phase particle size of 2–256 nm have been studied. The main features of the Fischer–Tropsch (FT) synthesis of synthetic hydrocarbons (HCs) in the presence of these systems have been revealed; the effect of the active phase concentration in the slurry on the selectivity for products with the C₁₁₊ chain length has been determined. It has been shown that a decrease in the particle size of the disperse system leads to an increase in the resistance of the iron carbide phase to oxidation by oxygen-containing products formed in the HC synthesis reaction.
