In comparison with the freshly reduced catalyst, the pre-carburized catalyst showed similar activity for the formation of hydrocarbons at the steady state and shorter period of activation which decreased with the degree of carburization. The pre-carburization was observed to reduce the strength and to raise the amount of the CO adsorption. Since no significant differences were observed between the carburizations with CO/He and CO/H_2, it was confirmed that the role of the carburization during synthesis was not the formation of reaction intermediates but the development of the active surface available for catalysis., 長崎大学教養部紀要. 自然科学篇. 1984, 25(1), p.25-36}, pages = {25--36}, title = {FORMATION OF ACTIVE SITES ON IRON CATALYST}, volume = {25}, year = {1984} }
