Deactivation of commercially relevant cobalt catalysts for Low Temperature Fischer-Tropsch (LTFT) synthesis is discussed with a focus on the two main long-term deactivation mechanisms proposed: Carbon deposits covering the catalytic surface and re-oxidation of the cobalt metal. There is a great variety in commercial, demonstration or pilot LTFT operations in terms of reactor systems employed, catalyst formulations and process conditions. Lack of sufficient data makes it difficult to correlate the deactivation mechanism with the actual process and catalyst design. It is well known that long term catalyst deactivation is sensitive to the conditions the actual catalyst experiences in the reactor. Therefore, great care should be taken during start-up, shutdown and upsets to monitor and control process variables such as reactant concentrations, pressure and temperature which greatly affect deactivation mechanism and rate. Nevertheless, evidence so far shows that carbon deposition is the main long-term deactivation mechanism for most LTFT operations. It is intriguing that some reports indicate a low deactivation rate for multi-channel micro-reactors. In situ rejuvenation and regeneration of Co catalysts are economically necessary for extending their life to several years. The review covers information from open sources, but with a particular focus on patent literature.

“…For CVD, anodic oxidation and electrophoretic deposition the highest limitations exist. Larger catalyst bed heights are not necessarily a problem regarding the pressure drop due to low particle sizes (50 -150 µm) in the micro packed bed approach, as reported by Myrstad et al (2009).…”

“…However, no issue was observed in the work of Bakhtiary et al (2011) andHayer et al (2011). The aspect of residues from reaction can be much more challenging in the case of Fischer-Tropsch synthesis like in the work from Myrstad et al (2009). Here a wax fraction from the catalysis remains on the catalyst and a purge flow of solvent to remove the catalyst is necessary.…”

“…Some limitations of FT fixed bed reactors like high pressure drop and low mass and heat transfer in pellets may be overcome by the application of reactors with microstructures. The structures used mostly in microstructure reactors are honeycomb monoliths 11), 12) , foams 13) , knitted wires 14) and micro-channel reactors 15), 16) . The catalyst in microstructure reactors is usually either deposited as a thin layer over a structured support or is used itself as the support.…”

The purpose of this work is to study the performance of fixed and monolith bed reactors in Fischer-Tropsch (FT) synthesis by modeling these reactors. A pseudo-homogeneous 2D model was proposed for FT fixed and monolith bed reactors. The model results shows good agreement with experimental data reported in literatures. The performance of the FT reactors was investigated in industrial scale under low temperature FT conditions (pressure 2 MPa and temperature 230 ). The modeling results were organized in three sections, (1) effect of operating condition parameters, which have similar effects on both reactors, (2) effect of structure parameters, which have different effects such as pellet diameter on FT fixed bed reactors, and thermal support property, the number of channels per cross sectioon area (CPSI) and wash coated catalyst thickness on FT monolith bed reactors, and (3) comparison of FT fixed and monolith bed reactors.
