Title: Slurry phase Fischer-Tropsch synthesis: Cobalt plus a water-gas shift catalyst

Abstract

Experiments to study the cobalt-catalyzed and iron-catalyzed reactions of light 1-alkenes added to synthesis gas have been performed and analyzed. On cobalt, data have been obtained at 220{degrees}C, 0.45 to 1.48 MPA and a synthesis gas flow rate between 0.015 and 0.030 Nl/gcat/min with H{sub 2}/CO feeds of 1.45 to 2.25. On fused iron, data were collected at 248{degrees}C, 0.79 to 1.48 MPa and a synthesis gas flow rate between 0.005 and 0.030 Nl/gcat/min of H{sub 2}/CO feeds of 0.5 to 1.5 C{sub 2}H{sub 4}, C{sub 3}H{sub 6}, and 1-C{sub 4}H{sub 8} were added to the synthesis gas feed in concentrations ranging from 0.5 to 1.2 mol. % of total feed. 1-Alkenes incorporate into growing chains on the catalyst surface of both catalysts, probably by initiating and/or terminating the chain growth process. Only ethene is believed to propagate chain growth significantly. The propensity of the 1-alkenes to incorporate decreases with increasing carbon number of the 1-alkene. The double-{alpha} behavior which is exhibited by most Fischer-Tropsch catalysts can be explained as the sum of two growth processes, one stepwise single-carbon growth and the other 1-alkene incorporation. Both alkene addition study data and the effects of process variables on the selectivity ofmore » Fischer-Tropsch catalysts can be explained within the framework of this theory. 19 refs., 12 figs., 2 tabs.« less
