Cobalt manganese oxides were prepared using co-precipitation procedure and studied for the hydrogenation of Carbon
monoxide to light olefins. The kinetic experiments of Fischer-Tropsch synthesis on a well-characterized Co/Mn/30%wt
TiO2 catalyst were carried out in a fixed-bed micro reactor. Experimental conditions were as follows: temperature, 190-
280; total pressure, 1-15bar; H2/CO feed ratio (mol/mol), 1-3; space velocity, 3000-5000 h-1. 7 models for Fischer-
Tropsch synthesis reaction rate were derived using the Langmuir-Hinshelwood-Houngen-Watson (LHHW) approach. In
these models, different sites are assumed for FTS reactions. The kinetic parameters were estimated with non-linear
regression method. The activation energy was obtained 93.773 kj/mol for optimal rate.
