Rate equations for the fischer‐tropsch reaction on a promoted iron catalyst

Abstract

Intrinsic rates for the Fischer‐Tropsch synthesis reaction over a promoted iron catalyst fabricated at the Research Institute of the Petroleum Industry (RIPI) have been obtained in the temperature range of 290°C to 310°C, pressure range of 1500 to 2300 kPa, molar hydrogen to carbon monoxide ratio of 0.76 to 1.82, and a space velocity of 3300 h−1 under conditions of constant catalyst activity. To this end, the initial reaction rates have been measured at constant temperature (±1°C) in the absence of diffusion limitations, and power‐law equations have been fitted in terms of the hydrogen and carbon monoxide partial pressures for the reaction rates.

“…They also developed the kinetic mode along with the estimation of kinetic parameters to predict the effect of the operating conditions on HC distribution and CO conversion [23]. Rahmati et al [24] obtained an intrinsic rate for the FT synthesis with a tubular fixed bed reactor over a promoted Fe catalyst. Ma et al [25] investigated the influence of support type and Co cluster size in a fixed bed reactor by kinetic tests employing two Co=c À Al 2 O 3 catalysts with different average pore sizes and two Co=SiO 2 catalysts prepared on the same support but having different loadings.…”

“…Montazer-Rahmati et al [41] studied the FTS on Fe-HZSM5 and considered these key components: CO, H 2 , CO 2 , H 2 O, CH 4 , C 2 H 4 , C 2 H 6 , C 3 H 8 , n-C 4 , i-C 4 and C 5 + . Hence, the reaction network was considered as: …”
