ABSTRACT: Intercalated iron-graphite catalysts for the Fischer-Tropsch synthesis are stabilized more quickly and result in more reproducible product distributions when conditioned prior to initial use with a 4:1 mixture of H sub 2 + CO (total pressure = 1 atm) at 300 exp 0 C, rather than with hydrogen or carbon monoxide separately under the same conditions. Moreover, the initial activity for CO conversion of H sub 2 + CO-pretreated samples are approximately three times as large as those exhibited by H sub 2 - or CO-pretreated samples. Product distributions vary slightly with extent of reaction. For 10% CO conversion of a 150:600 torr mixture of CO:H sub 2 reacting at 300 exp 0 C, the percentages of CO sub 2 , CH sub 4 , and C sub 2 , C sub 3 , and C sub 4+ hydrocarbons in the reaction product were 9, 58, 18, 11, and 4%, respectively.
