“…However, catalyst attrition, causing plugging of downstream filters, product contamination and increased slurry viscosity, which leads to mass transfer limitations and eventually reactor shutdown is one of the major problems encountered with the industrial application of the Fe F-T catalysts in the slurry bubble column reactors (SBCRs) [6,7]. A SBCR has been considered as the preferred industrial reactor for the F-T synthesis due to its low capital cost, low pressure drop across the reactor, excellent heat transfer efficiency and capability of online catalyst addition and removal [8,9].…”
