Abstract:
In this study, a Pd catalyst was prepared with promoters such as CeO2, BaO and SrO in a washcoated form on a metallic monolith for autothermal reforming of methane to syngas for the Fischer-Tropsch synthesis. A reactor was installed with an electric heater in the form of the metallic monolith as a start-up device instead of a burner with which stable and fast start-ups (within 4 min) were achieved. Gas hourly space velocity and O2/CH4 governed methane conversion, while H2O/CH4 controlled H2/CO ratio. A methane conversion of approx. 96%, H2 + CO selectivity of approx. 85%, and H2/CO of approx. 2.6 were obtained under the conditions of gas hourly space velocity (GHSV) at 103 000 h−1, O2/CH4 = 0.7 and H2O/CH4 = 0.35.Keywords: AUTOTHERMAL REFORMING; PALLADIUM; SYNGAS; FISCHER-TROPSCH SYNTHESIS; H2/CO RATIO
