Summary: | •In this work, the mechanism and kinetic of the Fischer–Tropsch synthesis over Fe-Co-Ni catalyst was investigated in a fixed bed micro reactor.
The kinetic of the Fischer–Tropsch synthesis over a Fe-Co-Ni catalyst was investigated in a fixed bed micro reactor. Experimental conditions were varied as follow: reaction pressure 1–12bar, H2/CO feed ratio of 1, 1.5, 2 and space velocity of 4800h−1 at the temperature range of 250–280°C. Eighteen models according to the Langmuir–Hinshelwood–Hougen–Watson (LHHW) type rate equation were derived on the basis of detailed set of possible reaction mechanisms, and the reaction rate of this study is fitted fairly well by one kinetic expression based on LHHW mechanism. The kinetic parameters were estimated with non-linear regression method and the activation energy was 82.220kJ/mol for optimal kinetic model. |
