Comparison of Several Ammonia Catalysts Worked Under Industrial Conditions

Development of Ru catalysts for ammonia synthesis was investigated, assumed that hydrogen was supplied from the water electrolysis by using variable electricity from photovoltaic and wind turbine. Cerium oxide and carbon-based materials were used as the support material of ruthenium. Catalytic activity was measured under various reaction conditions, in which pressure, temperature, space velocity, and H2/N2 ratio were changed, supposing plant operation conditions. Optimization of catalyst composition and preparation procedure was carried out to obtain the catalysts for the demonstration test described in Chap. 16 .
