THE COMPOSITION OF THE MEDIA FOR THE HYDROGEN PRODUCTION

摘要

PURPOSE: A medium composition for manufacturing hydrogen is provided to be applied to Three-Reactor Chemical-Looping Process (TRLC) including methane reduction reaction, water oxidation reaction, and air oxidation reaction, thereby separating carbon dioxide from methane while hydrogen is being produced. CONSTITUTION: A medium composition for manufacturing hydrogen comprises complex iron oxide represented by the chemical formula 1. [Chemical formula 1] MeaOb-FecOd. In the formula 1, Me is any one or more than two selected from nickel (Ni), copper (Cu), and molybdenum, and a to d are the value based on the mole ratio The a and c satisfy 0.1a / c0.25. The complex iron oxide is dipped in a supporter, and the content of the supporter inside the composition is 60-95 weight%. The supporter is selected from zirconia, alumina, silica, ceria, titania, and a mixture oxide thereof. The composition is applied to Three-Reactor Chemical-Looping Process (TRLC).
