  Abstract

Hydrogen production via steam reforming of liquefaction liquid from marine algae over hydrothermal liquefaction was carried out at 873 ~ 1073 K with a commercial catalyst and Ni based K2TixOy added catalysts. Liquefaction liquid obtained by hydrothermal liquefaction (503 K, 2 h) was used as a reactant and comparison studies for catalytic activity over different catalysts (FCR-4-02, Ni/K2TixOy-Al2O3, Ni/K2TixOy-SiO2, Ni/K2TixOy-ZrO2/CeO2 and Ni/K2TixOy-MgO), reaction temperature were performed. Experimental results showed Ni/K2TixOy based catalysts (Ni/K2TixOy-Al2O3, Ni/K2TixOy-SiO2, Ni/K2TixOy-ZrO2/CeO2 and Ni/K2TixOy-MgO) have a higher activity than commercial catalyst (FCR-4-02) and In particular, a product composition was different depending on support materials. An acidic support (Al2O3) and a basic support (MgO) led to a higher selectivity for CO while a neutral support (SiO2) and a reducing support (ZrO2/CeO2) resulted in a higher CO2 selectivity due to water gas shift reaction.
