A method for the production of hydrogen by a steam reforming reaction of hydrothermal liquefaction liquid from macro algae using a catalyst of perovskite composite structure

摘要

The present invention relates to a catalyst for the stream reforming reaction of marine algae-derived hydrothermal liquefied raw materials and a method of producing hydrogen using the same. The present invention produces hydrogen from raw materials generated through a hydrothermal liquefaction reaction from marine algae by the steam reforming reaction of marine algae-derived hydrothermal liquefied raw materials using M1M2_xO_y catalyst of a Ni-supported perovskite complex structure. The present invention has effects of: being used as a non-food energy source which is not a food source without a necessity of cultivated land by using seaweed biomass unlike conventional grain and starch biomass as a raw material for hydrogen production; having a high productivity of one-year cycle and an excellent carbon dioxide reducing effect compared to other biomass; having higher reaction activity compared to Ni/Al_2O having a commercially available catalyst structure as hydrogen is produced by the steam reforming reaction of marine algae-derived hydrothermal liquefaction raw materials using M1M2_xO_y catalyst of a Ni-supported perovskite complex structure; and continuously maintaining a high hydrogen conversion rate even after long time steam reforming reaction.
