The conversion of synthesis gas to a broad spectrum of products via Fischer-Tropsch reaction is one of the most important processes to solve the problem of decreasing fossil fuel resources. The effects of some operating conditions on the performance of a new kind of perovskite nanocatalyst (LaFe0.5Mn0.5O3 ± δ ) in a fixed-bed catalyst microreactor were investigated.
Abstract
Operating conditions and selectivity of a new perovskite nanocatalyst were studied in Fischer-Tropsch synthesis using a fixed-bed microreactor. Selectivity equations were obtained using the experimental data collected from a hydrogenation process in a fixed-bed microreactor. The operating conditions were obtained by defining the design-of-experiment scope based on response surface methodology, on 3 levels and in 15 tests. The optimum selectivity for alkenes relative to alkanes was obtained at 349.7 °C, 3.2 bar, and a H2/CO volumetric ratio of 1. Also, the optimum selectivity for alkenes relative to the overall selectivity for other products was attained at 250 °C, 2.3 bar, and a feed volumetric ratio of 2.
