Crystallite growth was studied with an alumina supported catalyst in real time as a function of process conditions using the in-situ magnetometer. Sintering occurred via a combination of high CO and water partial pressures. It is proposed that particle growth proceeds via cobalt sub-carbonyl migration over the hydroxylated support surface.
