Fundamental studies of key aspects of gasification and cleaning/upgrading for syngas generation
Upgrading of Syngas From Gasification of Residual Biomass and Biogenic Fractions: Development and Testing of Steam Reforming Catalysts
Short Introductive summary
The main goal of our work is the development and testing of improved steam reforming catalysts to increase the H2 content in the syngas from gasification of biomass and biogenic fractions . Nickel-based catalysts are broadly used in steam reforming but are prone to deactivation by coking. Therefore, Ni/MgAl-LDO catalysts were developed, which have high surface area and basic sites that decrease carbon deposition. Cobalt was added, as it enhances performance by forming a Ni-Co alloy that increases nickel dispersion. Moreover, iron was incorporated because iron-based catalysts are active for the water-gas shift reaction. Catalytic steam methane reforming reaction was performed isothermally at the desired temperature, a constant H2O/CH4 molar ratio of 3.3:1, and pressure of 1 bar. Decreasing the temperature from 715 to 615 °C reduced CH4 conversion and H2 production. The highest CH4 conversion was for N24Co10Mg46Al20 catalyst, attributed to the synergistic effect of the Ni-Co alloy. The highest hydrogen yield was for Ni10Mg70Al20 catalyst, an outcome of high MgO content. Catalysts Ni24Mg56Al20, Ni10Mg70Al20, and N24Co10Mg46Al20 exhibited excellent stability over two reaction cycles.
