The effect of activation on the deactivation of a precipitated iron based catalyst

There has been renewed interest in the Fischer-Tropsch process since diesel fuel derived from natural gas Fischer-Tropsch processes can meet the proposed future legislation standards for sulphur emissions without further processing. Oil refineries producing diesel fuel on the other hand would have to invest $4-13 billion to meet the proposed sulphur content requirements. Also, Fischer-Tropsch processes using coal as a feedstock could become and attractive alternative to oil refining due to the large differential between crude oil and coal prices...A study was undertaken in order to investigate the effect of low hydrogen content synthesis gas (as would be derived from coal) on the performance and lifetime of an iron-based catalyst during the low temperature Fischer-Tropsch process. In particular, the effect of the activation procedure on the lifetime of the iron-based catalyst (deactivation behaviour) was investigated...
