Studies on the steam and CO 2 reforming of methane for GTL-FPSO applications

Abstract

Steam CO 2 reforming (SCR) of methane for the production of syngas was simulated using PRO-II and investigated over Ni-based catalysts for GTL-FPSO applications. The Ni-based catalysts were prepared by an impregnation method. The catalysts before and after the reaction were characterized by N 2 physisorption, XRD and TEM techniques. The conversion of CH 4 was increased by increasing the concentration of H 2O and CO 2 in the feed. For the application in Co-based Fischer–Tropsch synthesis, the synthesis gas ratio of H 2/CO = 1.85–2.0 in the SCR was designed by the modeling of PRO-II simulator, and identified in a fixed bed reactor system by controlling the feed molar ratios of CH 4:H 2O:CO 2. It was found that Ni/MgO catalyst is more desirable catalyst for the production of synthesis gas than Ni/γ-Al 2O 3 and Ru/TiO 2 catalysts on the point of the low carbon formation and suitable H 2/CO ratio for the GTL-FPSO applications with Co-based FT process.
