In this contribution we provide details of the BP-Johnson Matthey proprietary Fischer–Tropsch technology and the advanced CANS reactor and catalyst system. The advanced CANS catalyst carrier reactor provides superior heat transfer, reduced pressure drop and higher productivity that lead to major economic savings. Fundamental understanding of catalyst behaviour is also key to obtaining a catalyst that is stable over the lifetime of its use. Synthesis, calcination and reduction steps introduce changes in the catalyst properties prior to syngas introduction. In particular, the presence of water can affect the final catalyst performance. The activity of a good catalyst can be significantly reduced by a sub-optimal activation or start-up. Similarly, stable operation and minimising deactivation are vital for long and stable catalyst life, with years of operation without requiring regeneration. In this report we also share a fundamental study on the catalyst activation across different catalyst supports. This combines advanced in situ techniques with reactor testing to explore the role of the support on catalyst performance. The results illustrate the critical need for a logical and systematic catalyst development programme to explore these effects to optimise the whole FT process. The combination of a joint approach in development plays a key role in a long term success in a process. The fundamental catalyst understanding, optimisation and improvements in combination with the novel CANS reactor design maximise their potential and offer the potential for a world leading technology.
