The Role Of Accumulated Carbon In Deactivating Cobalt Catalysts During Ft Synthesis In A Slurry-Bubble-Column Reactor

摘要

The H_2 reactivity of carbon-related phases in slurry-bubble column used FT catalysts was studied using TGA-MS techniques.While the hydrogen treatment is quite effective at removing paraffinic wax components at relatively low temperature,about 250deg C,a fraction of the carbon was resistant to hydrogen even at 350deg C.This fraction of the carbon in used FT catalysts increases as on-stream-time increases.
