According to the chemical equation, copper oxide reacts with hydrogen to produce water and copper. Calculate according to the reaction equation
You know this equation, the specific calculation method
The catalyst manual contains the content of copper oxide. How many tons are installed? You can calculate the mass of copper oxide.
Containing 61% copper, 50 tons of catalyst are installed
Does the instruction manual say the copper content?

The water output (theoretical value) of copper-based catalysts is easy to calculate. Now that the manufacturer has told you the Cu content of the catalyst, which is 61%, then you can calculate that CuO is 73.27%, and Al2O3 assumes 5%, leaving 100%-73.27%-5% = 21.73% ZnO. This is easy to calculate. The water output can only be calculated by calculating copper oxide and zinc oxide. Your copper oxide has 50x73.27%=36.6346 tons, and zinc oxide has 50x21.73%=10.8654 tons. Calculate it by yourself according to the chemical reaction equation. The copper oxide produces 6.9 tons of water, and the zinc oxide produces 2.4 tons of water. The total is about 9.3 tons, accounting for about 18% of the total mass of the catalyst. Make a small spreadsheet yourself, just use a calculator. . .

Strange, the manufacturer's instructions in the poster's hand didn't tell you the ratio of the theoretical water output to the total mass of the catalyst? This ratio, for copper-based catalysts, is approximately between 16 and 19%. . The 18.62% estimated in the table above is about the same. . Copper-based catalysts are relatively easy to calculate. In the past, the calculation of the water output of iron-based catalysts for ammonia synthesis really confused many people. . . . :lol
