Industrial Metal Catalysts

Industrial metal catalysts for hydrodesulfurization use a cobalt-molybdenum/nickel-molybdenum system with a sulfur load capacity of 35 grams per 100 grams. Industrial metal catalysts for ammonia synthesis have a fused iron-based activity of at least 68% and last over 10 years. Industrial metal catalysts for denitrification use a vanadium-tungsten-titanium honeycomb structure with a conversion rate greater than 92%. Industrial metal catalysts for platinum-carbon fuel cells have a platinum loading of 0.3 milligrams per square centimeter. When recycling spent industrial metal catalysts, the recovery rate for cobalt-molybdenum is over 97%, the vanadium extraction rate from vanadium-tungsten-titanium is 89%, and the regeneration rate for platinum-carbon through incineration is 99.5%; the recycled materials go directly into making new industrial metal catalysts.
