Effect of Operating Conditions of High-Temperature Three-Phase Fischer-Tropsh Synthesis Pilot Plant on Key Process Parameters
The possibility, in principle, of high-temperature three-phase Fischer-Tropsch synthesis, which is implemented in the presence of iron-containing catalytic dispersions in a bubble column reactor, is demonstrated. The catalytic system is activated in situ in a CO stream. It is proved that the particle size of the iron-containing dispersion used as the catalyst for this process depends on the precursor solution injection technique and in no case does it exceed 50 nm. It is shown that the described three-phase high-temperature Fischer-Tropsch synthesis method makes it possible to achieve high process parameters, such as target products yield up to 138 g/m(3) with 90% selectivity of products formation. The properties of the developed catalyst enable it to perform for a prolonged period with high conversions without impairment of process selectivity.
