Abstract in another language
The effect of axial distribution of the intrinsic catalytic activity on the performance of a multi-tubular fixed bed Fischer–Tropsch reactor was investigated. The reactor was modelled based on kinetic data for a cobalt catalyst. The influence of pore diffusion on the effective rate of CO conversion was considered. The maximum temperature was limited to 240 °C to avoid excessive methane formation. In each case, the cooling temperature was set to a value 5 K below the ignition temperature to ensure a sufficient safety distance to thermal runaway. At first, the optimal activity for the standard case of a uniform axial activity was determined. The activity should then be limited for the given conditions to a value corresponding to a Co content in the catalyst of 13 wt to reach the highest CO conversion, here XCO = 41. For a reactor with two zones of equal length, but different catalytic activity, a mean value of the Co content of 31 wt is optimal, 23 wt in the front zone and 40 wt in the rear part of the tubes. XCO is then 51 compared to only 38 for uniform distribution and a Co content of 31 wt.
